MCP server for [Huly](https://huly.io/) integration.

## Installation

The standard configuration works with most MCP clients:

```json
{
  "mcpServers": {
    "huly": {
      "command": "npx",
      "args": ["-y", "@firfi/huly-mcp@latest"],
      "env": {
        "HULY_URL": "https://huly.app",
        "HULY_EMAIL": "your@email.com",
        "HULY_PASSWORD": "yourpassword",
        "HULY_WORKSPACE": "yourworkspace"
      }
    }
  }
}
```

<details>
<summary>Codex</summary>

Use Codex's MCP manager:

```bash
codex mcp add huly \
  --env HULY_URL=https://huly.app \
  --env HULY_EMAIL=your@email.com \
  --env HULY_PASSWORD=yourpassword \
  --env HULY_WORKSPACE=yourworkspace \
  -- npx -y @firfi/huly-mcp@latest
```

Or add it directly to `~/.codex/config.toml`:

```toml
[mcp_servers.huly]
command = "npx"
args = ["-y", "@firfi/huly-mcp@latest"]

[mcp_servers.huly.env]
HULY_URL = "https://huly.app"
HULY_EMAIL = "your@email.com"
HULY_PASSWORD = "yourpassword"
HULY_WORKSPACE = "yourworkspace"
```

      }
    }
  }
}
```

</details>

## Updating

The `@latest` tag asks the package runner for the newest version. Some MCP clients keep server processes or resolved installs alive, so restart or re-add the server when updating:

| Client | How to update |
|--------|--------------|
| **Codex** | `codex mcp remove huly` then re-add with the install command above. If your password has shell-sensitive characters, edit `~/.codex/config.toml` directly instead |
| **Claude Code** | `claude mcp remove huly` then re-add with the install command above |
| **Claude Desktop** | Restart the app (it runs `npx` on startup) |
| **VS Code / Cursor** | Restart the MCP server from the command palette/configured client or reload the window |
| **OpenCode** | Restart OpenCode or start a new session after config changes |
| **npx (manual)** | `npx -y @firfi/huly-mcp@latest` — the `-y` flag auto-confirms install prompts |

## HTTP Transport

By default, the server uses stdio transport. For HTTP transport (Streamable HTTP):

```bash
HULY_URL=https://huly.app \
HULY_EMAIL=your@email.com \
HULY_PASSWORD=yourpassword \
HULY_WORKSPACE=yourworkspace \
MCP_TRANSPORT=http \
npx -y @firfi/huly-mcp@latest
```

Server listens on `http://127.0.0.1:3000/mcp` by default.

Configure with `MCP_HTTP_PORT` and `MCP_HTTP_HOST`:

```bash
MCP_TRANSPORT=http MCP_HTTP_PORT=8080 MCP_HTTP_HOST=0.0.0.0 npx -y @firfi/huly-mcp@latest
```

### HTTP MCP Protocol Support

The HTTP server supports both the existing SDK initialize-compatible Streamable HTTP flow and the 2026 stateless HTTP flow at the same `/mcp` endpoint. Dispatch is per request:

- Requests with `MCP-Protocol-Version: 2026-07-28`, matching `_meta.io.modelcontextprotocol/protocolVersion`, or `server/discover` use the 2026 stateless dispatcher.
- Requests without 2026 protocol signals continue through the SDK transport for compatibility with existing clients.

The 2026 path requires one JSON-RPC message per POST, `Accept: application/json, text/event-stream`, `Mcp-Method`, method-specific `Mcp-Name`, and per-request `_meta.io.modelcontextprotocol/*` client metadata. Huly credentials are still configured separately through env vars or supported `x-huly-*` headers.

For hosted or tunneled HTTP deployments, you can require an MCP endpoint bearer token:

```bash
MCP_TRANSPORT=http \
MCP_AUTH_TOKEN="$(openssl rand -hex 32)" \
npx -y @firfi/huly-mcp@latest
```

HTTP clients must then send:

```http
Authorization: Bearer <MCP_AUTH_TOKEN>
```

`MCP_AUTH_TOKEN` protects only the MCP HTTP `/mcp` endpoint. It is unrelated to `HULY_TOKEN`, does not authenticate to Huly, and does not replace `HULY_EMAIL` / `HULY_PASSWORD` / `HULY_TOKEN`. Huly credentials are still required through process env vars or, for hosted URL deployments, the supported `x-huly-*` headers. Stdio deployments do not use `MCP_AUTH_TOKEN`.

### Hosted HTTP Header Configuration

For hosted URL deployments, keep the server process configured with `MCP_TRANSPORT=http`. A hosting layer can forward per-session Huly credentials as request headers, so one hosted server can serve different Huly workspaces without process-wide `HULY_*` env vars.

Supported v1 headers:

| Header | Required | Description |
|--------|----------|-------------|
| `x-huly-url` | Yes | Huly instance URL |
| `x-huly-workspace` | Yes | Workspace identifier |
| `x-huly-token` | Yes | Huly API token |
| `x-huly-connection-timeout` | No | Connection timeout in ms |

If any `x-huly-*` header is present, all required headers must be present. Missing values are not filled from environment variables. Email/password auth is not supported in hosted header configuration v1.

For a Smithery publish schema example, see [docs/SMITHERY_URL_PUBLISH.md](docs/SMITHERY_URL_PUBLISH.md).

## Environment Variables

| Variable | Required | Description |
|----------|----------|-------------|
| `HULY_URL` | Yes | Huly instance URL |
| `HULY_EMAIL` | Auth* | Account email |
| `HULY_PASSWORD` | Auth* | Account password |
| `HULY_TOKEN` | Auth* | API token (alternative to email/password) |
| `HULY_WORKSPACE` | Yes | Workspace identifier |
| `HULY_CONNECTION_TIMEOUT` | No | Connection timeout in ms. Omit to use the package default. |
| `MCP_TRANSPORT` | No | Transport type: `stdio` (default) or `http` |
| `MCP_HTTP_PORT` | No | HTTP server port (falls back to `PORT`, then 3000) |
| `MCP_HTTP_HOST` | No | HTTP server host. Omit to bind to the package default loopback host. |
| `MCP_AUTH_TOKEN` | No | Optional bearer token required by HTTP clients for `/mcp`. This protects the MCP endpoint only; it is not a Huly API token. |
| `TOOLSETS` | No | Comma-separated tool categories to expose. If unset, all tools are exposed. Example: `issues,projects,search` |

*Auth: Provide either `HULY_EMAIL` + `HULY_PASSWORD` or `HULY_TOKEN`.

## Built-in Diagnostic Tools

`get_version` returns the current server version and latest npm version.

`get_huly_context` returns sanitized runtime/configuration context for the current MCP session without connecting to Huly. It reports package version, transport, auth mode, sanitized Huly URL origin/host/protocol, workspace, timeout, config sources, and toolset filtering. Tokens, passwords, email values, credential headers, URL paths, URL query strings, and URL credentials are never returned.

## MCP Resources

The server exposes read-only MCP Resources as JSON context for clients that support `resources/read`.

<!-- resources:start -->
<!-- AUTO-GENERATED from src/mcp/resources.ts resourceTemplates. Do not edit manually. Run `pnpm update-readme` to regenerate. -->
| Template | Name | Description | MIME Type |
|----------|------|-------------|-----------|
| `huly://projects/{project}` | `huly-project` | Read full details for a Huly tracker project by project identifier, for example huly://projects/HULY. | `application/json` |
| `huly://issues/{issue}` | `huly-issue` | Read full details for a Huly issue by full issue identifier, for example huly://issues/HULY-123. | `application/json` |
| `huly://projects/{project}/issues/{issue}` | `huly-project-issue` | Read full details for a Huly issue by project identifier and issue number, for example huly://projects/HULY/issues/123. | `application/json` |
<!-- resources:end -->

`resources/list` returns concrete active project resources. Issue resources are template-based: use `resources/templates/list` to discover supported issue URI templates, then read a known issue URI.

## Roadmap

The roadmap is driven by SDK parity and the project principle that this server should expose LLM-first tools: clear names, self-contained parameters, automatic identifier resolution, and single-call correctness. The audited source of truth lives in [plans/huly-sdk-gap-matrix.md](plans/huly-sdk-gap-matrix.md), with machine-checkable classifications in [plans/sdk-parity-ledger.json](plans/sdk-parity-ledger.json).

Highest-value additions for coding agents:

- Generic space follow-ups: role assignment mutations, role/permission definition writes, generic space creation, and module-specific wrappers above the shared space foundation.
- SDK discovery phase 2: space types, roles, permissions, plugin configuration, sequence metadata, and richer tool hints.
- Drive follow-ups: drive create/update/delete, item move/rename/delete, adding new versions to existing files, permissions, and comments/activity.
- Planner/ToDos: personal and project ToDo CRUD, scheduling, complete/reopen, priority, privacy/visibility, and document action items.
- Recruiting: vacancies, candidates, applications, application statuses, recruiter assignment, reviews, opinions, skills, and related comments/attachments/activity.
- Controlled documents and trainings: controlled document spaces/projects, review/approval workflows, templates, categories, snapshots/history, training assignments, attempts, scoring, and results.
- Module-specific tag wrappers for tag-backed concepts such as recruiting skills, board labels, controlled-document labels, and contact tags.

Planned feature surfaces:

- Implemented foundation: generic space discovery and safe existing-space administration are covered by `spaces` tools for listing/getting spaces, listing/getting space types, reading permissions, updating common metadata, adding/removing members, and replacing owners.
- Controlled Documents / TraceX documents: controlled spaces/projects, controlled document CRUD, quality/technical docs, co-authors/reviewers/approvers, e-signature workflows, release/effective-date metadata, change control, training linkage, controlled-document comments, and snapshots/history.
- Products and product versions: product spaces, members, descriptions, attachments, versions, version state transitions, and change-control links.
- Trainings, questions, and assessments: training revisions, releases, requests, due dates, max attempts, question banks, answer options, correct-answer data, submissions, scoring, and reporting.
- Drive: first slice covers listing/getting drives, path traversal/list/get items, idempotent folder creation, uploads with parent creation, version listing, and restoring existing versions. Remaining gaps are drive create/update/delete, item move/rename/delete, adding new versions to existing files, comments/activity, and permissions/members.
- HR: departments, nested departments, staff mixins, managers, subscribers, team leads, request types, PTO/sick/overtime/remote requests, public holidays, and schedule/table reports.
- Recruiting: vacancies, talents/candidates, applications, matches, reviews, verdicts/opinions, vacancy-company lists, skills, and recruiting-specific custom fields/relations.
- Surveys and polls: survey CRUD, poll creation/attachment, survey question data, completion status, and results.
- Generic approval requests: create/list/approve/reject/cancel approval requests, decision comments, required approval counts, request status, and requested/approved/rejected people.
- Boards: board CRUD, board cards, status workflows, members/assignees, location, cover/archive fields, board labels, and menu/archive views.
- Inventory: categories, products, variants/SKUs, product photos, attachments, activity/comments, and hierarchy tools.
- Leads write surface: create/update/delete funnels and leads, status changes, assignment, start dates, customer descriptions, person customer support, and lead comments/attachments/labels/relations.
- Contacts: person channels, social identities, provider discovery, contact statuses, notes/comments, person attachments, person merge, employee invite/create/kick/reinvite, and inactive employee management.
- Calendar: calendar CRUD/config, external calendar sync metadata, primary calendar management, schedule objects, participant mutations, and RSVP/status support when stable.
- Team planner and schedule reporting: team agendas, workload/capacity summaries, and visibility-aware free/busy views across members/projects.
- Virtual office and meetings: offices, floors, rooms, access/language/default recording/transcription settings, meeting schedules, active participants, room info, meeting notes/transcript records (minutes), recordings, and device preferences.
- Chat and communication: direct-message send/update/delete, group DMs, channel member mutations, join/leave/request access, archive/unarchive, star/favorite channels, close/reopen conversations, pinned messages, message attachments, translation, applets, in-message polls, and guest communication settings.
- Notifications and activity: browser/push subscription internals, provider defaults, UI presenter/viewlet metadata, and activity control/extension metadata.
- Attachments and media: previews/preview metadata and friendly wrappers for additional object types beyond issue/document.
- Core schema and workspace administration: attribute/property create/update/delete/hide, enum CRUD/options, sequence management, role assignment mutations, role/permission definition writes, generic space creation, global space admins, integrations registry, invite settings, role capability settings, and workspace setting metadata.
- Integrations: GitHub repository/project mappings and sync metadata (deferred), Google Calendar connect/configure/sync controls, Bitrix entity/field mappings and sync status, Gmail/email channel messages, Telegram messages, Huly Mail/Mail plugin behavior, AI assistant integration state, and AI bot configuration if server-side APIs expose stable behavior.
- Templates, rating, support, billing, analytics, views, workbench, and preferences: message templates/categories/fields, document/person rating data blocked by unpublished `@hcengineering/rating` SDK package (#90), support conversations, billing tier/status discovery, onboarding channels, saved filtered views, user view preferences, tabs/widgets/apps, and module preference discovery/update.
- Document-specific gaps: snapshot restore, backlinks, notes, structured action items/tables, PDF/export, advanced document relationships, and document printing/export once SDK support is safe.

MCP resource roadmap:

- Return resource links from list/search tool results for direct `resources/read` follow-up.
- Add document resources when document reads have a stable URI shape and context-friendly payload.
- Consider scoped/paginated issue listing only when filters prevent very large `resources/list` responses.
- Consider resource `subscribe` and `listChanged` support after stateful sessions and a Huly change source are available.

SDK upgrade revisit:

- Revisit `@hcengineering/*` upgrades when a newer release is available after `0.7.423`.
- Verify published tarballs, not only npm metadata, before accepting SDK upgrades.
- Require valid published declaration files for direct Huly dependencies.
- Upgrade direct Huly package declarations coherently in `package.json`; do not accept lockfile-only transitive rewrites.
- Run `pnpm check-all` and local Huly integration tests before treating an SDK upgrade as viable.

### Projects

| Tool | Description |
|------|-------------|
| `list_project_target_preferences` | List low-level per-project tracker target preference records. These Huly ProjectTargetPreference records are attached to projects and used by tracker UI/workflows to remember target-related preference props. Omit project to list recent preferences across projects, or pass a project identifier to inspect one project's preference. Props are SDK-open key/value payloads. |
| `upsert_project_target_preference` | Create or update the low-level ProjectTargetPreference record for a project. This refreshes usedOn and merges SDK-open target preference props by key. Use for tracker SDK parity or advanced administration; ordinary project and issue workflows usually do not need this tool. |
| `list_projects` | List all Huly projects. Returns projects sorted by name. Supports filtering by archived status. |
| `get_project` | Get full details of a Huly project including its statuses. Returns project name, description, archived flag, default status, and all available statuses. |
| `list_statuses` | List all issue statuses for a Huly project with workflow category and default info. Returns status name, category, and isDefault. Use this to discover valid statuses before creating or updating issues. |
| `create_project` | Create a new Huly tracker project. Idempotent: returns existing project if one with the same identifier already exists (created=false). Identifier must be 1-5 uppercase alphanumeric chars starting with a letter. |
| `update_project` | Update a Huly project. Only provided fields are modified. Set description to null to clear it. |
| `delete_project` | Permanently delete a Huly project. All issues, milestones, and components in this project will be orphaned. This action cannot be undone. |

### Issues

| Tool | Description |
|------|-------------|
| `preview_deletion` | Preview the impact of deleting a Huly entity before actually deleting it. Shows affected sub-entities, relations, and warnings. Supports issues, projects, components, and milestones. Use this to understand cascade effects before calling a delete operation. |
| `list_issues` | Query Huly issues with optional filters. Returns issues sorted by modification date (newest first). Supports filtering by project, exact workflow status name (status), Huly SDK task.statusCategory key (statusCategory: UnStarted, ToDo, Active, Won, Lost), assignee, component, and parentIssue (to list children of a specific issue). Supports searching by title substring (titleSearch) and description content (descriptionSearch). |
| `get_issue` | Retrieve full details for a Huly issue including markdown description. Use this to view issue content, comments, or full metadata. |
| `create_issue` | Create a new issue in a Huly project. Optionally set taskType by ID or display name; it is resolved within the target project's project type, and status is validated against that task type's workflow. Use list_task_types or get_project_type to discover valid task types and statuses. Optionally create as a sub-issue by specifying parentIssue. Description supports markdown formatting. Returns the created issue identifier. |
| `update_issue` | Update fields on an existing Huly issue. Optionally set taskType by ID or display name; it is resolved within the target project's project type, and the status is preserved only when valid for the new task type. Use list_task_types or get_project_type to discover valid task types and statuses. Only provided fields are modified. Description updates support markdown. |
| `add_issue_label` | Add a tag/label to a Huly issue. Creates the tag if it doesn't exist in the project. |
| `remove_issue_label` | Remove a tag/label from a Huly issue. Detaches the label reference; does not delete the label definition. |
| `delete_issue` | Permanently delete a Huly issue. This action cannot be undone. |
| `move_issue` | Move an issue to a new parent (making it a sub-issue) or to top-level (null). Updates parent/child relationships and sub-issue counts. |
| `list_components` | List components in a Huly project. Components organize issues by area/feature. Returns components sorted by modification date (newest first). |
| `get_component` | Retrieve full details for a Huly component. Use this to view component content and metadata. |

| `list_issue_templates` | List issue templates in a Huly project. Templates define reusable issue configurations. Returns templates sorted by modification date (newest first). |
| `get_issue_template` | Retrieve full details for a Huly issue template including children (sub-task templates). Use this to view template content, default values, and child template IDs. |
| `create_issue_template` | Create a new issue template in a Huly project. Templates define default values for new issues. Optionally include children (sub-task templates) that will become sub-issues when creating issues from this template. Returns the created template ID and title. |
| `create_issue_from_template` | Create a new issue from a template. Applies template defaults, allowing overrides for specific fields. If the template has children (sub-task templates), sub-issues are created automatically unless includeChildren is set to false. Returns the created issue identifier and count of children created. |
| `update_issue_template` | Update fields on an existing Huly issue template. Only provided fields are modified. |
| `delete_issue_template` | Permanently delete a Huly issue template. This action cannot be undone. |
| `add_template_child` | Add a child (sub-task) template to an issue template. The child defines default values for sub-issues created when using create_issue_from_template. Returns the child template ID. |
| `remove_template_child` | Remove a child (sub-task) template from an issue template by its child ID. Get child IDs from get_issue_template response. |
| `add_issue_relation` | Add a relation between two issues. Relation types: 'blocks' (source blocks target — pushes into target's blockedBy), 'is-blocked-by' (source is blocked by target — pushes into source's blockedBy), 'relates-to' (bidirectional link — updates both sides). targetIssue accepts cross-project identifiers like 'OTHER-42'. No-op if the relation already exists. |
| `remove_issue_relation` | Remove a relation between two issues. Mirrors add_issue_relation: 'blocks' pulls from target's blockedBy, 'is-blocked-by' pulls from source's blockedBy, 'relates-to' pulls from both sides. No-op if the relation doesn't exist. |
| `list_issue_relations` | List all relations of an issue. Returns blockedBy (issues blocking this one), blocks (issues this one blocks), relations (bidirectional issue links), and documents (linked documents with title/teamspace). |
| `link_document_to_issue` | Link a Huly document to an issue. The link appears in the issue's Relations panel in the UI. Idempotent: no-op if the document is already linked. Use list_issue_relations to see linked documents. |
| `unlink_document_from_issue` | Remove a document link from an issue. Idempotent: no-op if the document is not linked. |
| `list_related_issue_targets` | List rules that choose the default destination project for related issues. A spaceRule says related issues from one space default to targetProject. A classRule says related issues for one object class default to targetProject. targetProject is a project identifier, or null for no default destination project. |
| `set_related_issue_target` | Set the default destination project for related issues from a space or object class. For space, creates or updates a spaceRule. For objectClass, only updates an existing classRule; this tool never creates classRule targets. Pass targetProject as a project identifier, or null to clear the default destination project. |
| `delete_related_issue_space_target` | Delete the spaceRule that chooses the default destination project for related issues from one space. This only deletes spaceRule targets; classRule deletion is intentionally unsupported because class rules may be model-provided. |

### Comments

| Tool | Description |
|------|-------------|
| `list_comments` | List comments on a Huly issue. Returns comments sorted by creation date (oldest first). |
| `add_comment` | Add a comment to a Huly issue. Comment body supports markdown formatting. |
| `update_comment` | Update an existing comment on a Huly issue. Comment body supports markdown formatting. |
| `delete_comment` | Delete a comment from a Huly issue. This action cannot be undone. |

### Milestones

| Tool | Description |
|------|-------------|

| `update_milestone` | Update fields on an existing Huly milestone. Only provided fields are modified. |
| `set_issue_milestone` | Set or clear the milestone on a Huly issue. Pass null for milestone to clear it. |
| `delete_milestone` | Permanently delete a Huly milestone. This action cannot be undone. |

### Documents

| Tool | Description |
|------|-------------|
| `list_document_snapshots` | List version-history snapshots for one Huly document. A snapshot is a saved point-in-time copy from the document's change history. Resolve the document by teamspace plus document title or ID. Returns snapshotId, documentId, teamspaceId, title, parentDocumentId, and timestamps; markdown content is intentionally omitted. Use get_document_snapshot with snapshotId when reading content. |
| `get_document_snapshot` | Get one point-in-time Huly document history snapshot and return markdown content. Resolve the document by teamspace plus document title or ID; resolve the snapshot by snapshotId, exact snapshot title, or exact createdOn timestamp. Prefer snapshotId from list_document_snapshots when titles or dates may collide. Restore is out of scope. |
| `list_teamspaces` | List all Huly document teamspaces. Returns teamspaces sorted by name. Supports filtering by archived status. |
| `get_teamspace` | Get details for a Huly document teamspace including document count. Finds by name or ID, including archived teamspaces. |
| `create_teamspace` | Create a new Huly document teamspace. Idempotent: returns existing teamspace if one with the same name exists. |
| `update_teamspace` | Update fields on an existing Huly document teamspace. Only provided fields are modified. Set description to null to clear it. |
| `delete_teamspace` | Permanently delete a Huly document teamspace. This action cannot be undone. |
| `list_documents` | List documents in a Huly teamspace. Returns documents sorted by modification date (newest first). Each result includes a 'url' field pointing to the document in the Huly web app. Supports searching by title substring (titleSearch) and content (contentSearch). |
| `get_document` | Retrieve full details for a Huly document including markdown content and a 'url' field pointing to the document in the Huly web app. Use this to view document content and metadata. |
| `create_document` | Create a new document in a Huly teamspace. Content is markdown and supports native Mermaid diagrams (```mermaid blocks render interactively in Huly UI). Use markdown links to current-workspace Huly browse URLs for native references; Huly browse links returned in get_document content round-trip as native references. The URL identifies the object; link text is display text; plain issue keys stay text. External URLs stay normal markdown links. Optionally pass parent as a document title or ID to create a nested child document; invalid parents fail instead of silently creating a top-level document. Returns the created document id and a 'url' field pointing to the document in the Huly web app. Use link_document_to_issue only if you also want an issue-document association. |
| `edit_document` | Edit an existing Huly document. You may rename with title and/or edit the body. Body editing has two mutually exclusive modes: (1) content replaces the entire markdown body, (2) old_text + new_text performs exact targeted search-and-replace. Use markdown links to current-workspace Huly browse URLs for native references; Huly browse links returned in get_document content round-trip as native references. The URL identifies the object; link text is display text; plain issue keys stay text. External URLs stay normal markdown links. For targeted replace, multiple matches error unless replace_all is true; empty new_text deletes matched text. Content supports native Mermaid diagrams. Returns a 'url' field pointing to the document in the Huly web app. |
| `list_inline_comments` | List inline comment threads from a Huly document. Extracts comments embedded in document content as ProseMirror marks. Each comment includes the highlighted text and thread ID. Set includeReplies=true to also fetch thread reply messages with sender names. |

| `restore_drive_file_version` | Restore an existing Drive file version by version id or numeric version. Idempotent when the requested version is already current and does not increment the file version counter. |

### Labels

| Tool | Description |
|------|-------------|
| `list_labels` | List label/tag definitions in the workspace. Labels are global (not project-scoped). Returns labels for tracker issues sorted by modification date (newest first). |
| `create_label` | Create a new label/tag definition in the workspace. Labels are global and can be attached to any issue. Returns existing label if one with the same title already exists (created=false). Use add_issue_label to attach a label to a specific issue. |
| `update_label` | Update a label/tag definition. Accepts label ID or title. Only provided fields are modified. |
| `delete_label` | Permanently delete a label/tag definition. Accepts label ID or title. This action cannot be undone. |

### Leads

| Tool | Description |
|------|-------------|
| `list_funnels` | List all Huly sales funnels (lead pipelines). Returns each funnel's stable ID and display name, sorted by name. Supports filtering by archived status. |
| `list_leads` | Query Huly leads in a funnel with optional filters. Pass the funnel ID returned by list_funnels, or a funnel name for convenience lookup. Returns leads sorted by modification date (newest first). Supports filtering by status, assignee, and title search. |
| `get_lead` | Retrieve full details for a Huly lead including markdown description, customer name, funnel ID and funnel name, and status. Lead identifiers follow the upstream Huly format like 'LEAD-1'. |

### Planner

| Tool | Description |
|------|-------------|
| `list_todos` | List Huly Planner ToDos. Empty input returns up to 50 ToDos in planner order with all completion states. Use owner, issue, title, due date, priority, visibility, or completion filters to narrow results. |
| `get_todo` | Get one Planner ToDo by raw todoId or by human locator such as issue + title + owner. Returns stable ToDo fields, owner, attachment context, description, labels count, and work slot count. |
| `create_todo` | Create a Planner ToDo. Omit attachedTo for a personal ToDo, or pass attachedTo.type=issue with project and identifier for an issue action item. Omit owner to use the authenticated user. |
| `update_todo` | Update a Planner ToDo by human locator or raw todoId. Supports title, markdown description, owner, dueDate including null to clear, priority, and visibility. |
| `complete_todo` | Complete a Planner ToDo by setting doneOn. Huly may trim future work slots and run issue automation when the ToDo is attached to an issue. |
| `reopen_todo` | Reopen a completed Planner ToDo by clearing doneOn. Human locators search completed ToDos by default; raw todoId locators target that exact ToDo. |
| `delete_todo` | Delete a Planner ToDo. This is destructive; deleting the last open issue ToDo can cause Huly classic issue status automation. |
| `schedule_todo` | Schedule a Planner ToDo by raw todoId or human locator, creating a work slot with ToDo title, description, and visibility metadata. |
| `unschedule_todo` | Remove ToDo work slots. Pass either workSlotId to remove one slot, locator with scope=all, or locator with scope=future and optional from. |

### Processes

| Tool | Description |
|------|-------------|
| `list_processes` | List read-only Huly Process workflow definitions. Optionally filter by the master tag/card type that workflows attach to. Returns process IDs, names, attached card type, automation flags, and state/transition counts. |
| `get_process` | Get one Huly Process workflow definition by process ID or exact display name. If a name is ambiguous, the tool returns a typed error with candidate IDs instead of guessing. |
| `list_process_executions` | List read-only Huly Process workflow executions. Supports filters by process ID/name, card/document ID/title, and status. Rows are enriched with process name, card title, and current state title when available. |
| `start_process` | Start a new active Huly Process workflow execution on a card/document. Accepts process ID or exact process name, and card/document ID or exact title; ambiguous names or titles fail with candidate IDs. This is not idempotent: each successful call creates a new execution unless the process forbids parallel active executions for the same card, in which case the existing active execution ID is returned in a typed error. |
| `cancel_execution` | Idempotently cancel one Huly Process execution by execution ID. Active executions are marked cancelled; already-cancelled executions succeed with cancelled=false; completed executions fail without changing history. |

| `list_huly_sequences` | List read-only Huly sequence counters from core.class.Sequence and core.class.CustomSequence. Returns sequence id, attached class id, current non-negative integer value, and custom prefix when present. |
| `describe_huly_space_type_capabilities` | Describe one Huly SpaceType by id or exact name in a single read-only call. Returns descriptor metadata, base/target classes, roles, role permissions, default members, autoJoin, and the stored role-assignment shape. |

### Spaces

| Tool | Description |
|------|-------------|

| `list_space_permissions` | List core Huly Permission records for space/workspace access control discovery. Filter by scope, objectClass, or search text. This is read-only and does not assign permissions. |
| `update_space` | Update safe common metadata on an existing Huly space: name, description, private, archived, and autoJoin. Does not create/delete spaces or mutate module-specific required fields. |
| `add_space_members` | Idempotently add members to an existing Huly space. Members accept account UUID, exact email, or exact person display name and resolve to Huly account UUIDs before replacing the full members array. |
| `remove_space_members` | Idempotently remove members from an existing Huly space. Members accept account UUID, exact email, or exact person display name and resolve to Huly account UUIDs before replacing the full members array. |
| `set_space_owners` | Replace owners on an existing Huly space. Owners accept account UUID, exact email, or exact person display name. By default, owners are also ensured in members. |

### Tag-Categories

| `update_tag` | Update a generic Huly tag definition. The tag argument accepts a tag ID or exact title, resolved within targetClass. |
| `delete_tag` | Delete a generic Huly tag definition by ID or exact title, resolved within targetClass. This deletes the tag definition, not only one object's tag reference. |
| `list_attached_tags` | List generic Huly TagReference rows attached to one raw object collection. Requires objectId, objectClass, space, and collection because this is an SDK-level tool. |
| `attach_tag` | Attach a generic Huly tag to one raw object collection. Requires targetClass for the tag definition and objectId/objectClass/space/collection for the TagReference. Idempotent for the same object, collection, and tag. |

## Troubleshooting

### Passwords with special characters

If your Huly password contains characters like `*`, `%`, `!`, or `#`, passing it via CLI environment flags such as `-e` or `--env` may fail because the shell interprets these characters before they reach the process.

**Solution**: Edit your MCP config file directly instead of passing the password through the shell:

- Codex: `~/.codex/config.toml`
- Claude Code: `~/.claude.json` (user scope) or `.mcp.json` (project scope)
- Claude Desktop: `claude_desktop_config.json` in the location listed in the installation section
- VS Code and Cursor: use the client config location from the installation section; avoid committing workspace files that contain real credentials
- Windsurf: edit your Windsurf MCP configuration file directly
- OpenCode: `~/.config/opencode/opencode.json`

For Claude JSON config, the shell-sensitive characters above can be written directly. JSON-reserved characters such as `"` and `\` still need normal JSON escaping:

```json
{
  "mcpServers": {
    "huly": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@firfi/huly-mcp@latest"],
      "env": {
        "HULY_URL": "https://your-huly-instance.com",
        "HULY_EMAIL": "you@example.com",
        "HULY_PASSWORD": "p@ss*w0rd!#%",
        "HULY_WORKSPACE": "your-workspace"
      }
    }
  }
}
```

Alternatively, use `HULY_TOKEN` instead of email/password to bypass password auth entirely (see [Environment Variables](#environment-variables)).

### MCP client shows "Failed to reconnect"

After changing MCP configuration, some clients (including Claude Code) require a full restart — not just a reconnect. Exit the application completely and reopen it.

You can verify the connection works independently with:
```bash
claude mcp list  # Should show "Connected"
```

### Self-hosted Huly: account locked after failed login attempts

Huly locks password login after 5 failed API authentication attempts. This commonly happens during initial setup when the password is misconfigured. The lock persists in the database across service restarts.

**Symptoms**: `PasswordLoginLocked` error from the MCP server, and the Huly web UI shows "Password login is locked due to too many failed attempts. Please use an OTP login method to unlock your account." (OTP won't work without SMTP configured.)

**Fix** — reset the lock counter in CockroachDB:

```bash
# Find your account UUID and check lock status
docker exec -e PGPASSWORD=<your_cockroach_password> <cockroach_container> \
  cockroach sql --host=localhost --user=<db_user> --database=defaultdb --insecure \
  -e "SELECT uuid, failed_login_attempts FROM global_account.account;"

# Reset the counter
docker exec -e PGPASSWORD=<your_cockroach_password> <cockroach_container> \
  cockroach sql --host=localhost --user=<db_user> --database=defaultdb --insecure \
  -e "UPDATE global_account.account SET failed_login_attempts = 0 WHERE uuid = '<your_account_uuid>';"
```

The CockroachDB credentials can be found in your Huly `compose.yml` or via `docker exec <cockroach_container> env | grep COCKROACH`.

### Windows-specific notes

- **Bash wrapper scripts** (sourcing `.env` files) may not work reliably when launched by MCP clients on Windows. Prefer setting env vars directly in the MCP config JSON.
- **Docker pulls over SSH** may fail on Windows due to credential manager issues. Pull images from the server desktop if needed.
