Persistent memory. Millisecond code search.
\n\n## Your agent knows code. Give it the decisions behind yours.\n\nConnect your code, docs, and conversations so your agents can find the right\nfiles, recall saved decisions, and build on past work across sessions and tools.\n\n\n\n## Start free with MCP\n\n**10,000 monthly credits. No credit card required.**\n\nWorks with Claude Code, Cursor, Codex, GitHub Copilot, Gemini CLI, Qwen Code,\nKimi Code, Muse Code, ZCode, Zed, and [more MCP clients](docs/clients.md), on\nClaude, GPT, Gemini, Kimi, GLM, Qwen, and other models.\nCreate your account or sign in during MCP onboarding. No separate website signup needed.\n\n**macOS and Linux**\n\n```sh\ncurl -fsSL https://contextstream.io/scripts/mcp.sh | bash\n```\n\n**Windows PowerShell**\n\n```powershell\nirm https://contextstream.io/scripts/mcp.ps1 | iex\n```\n\nPaste the command into your terminal and follow onboarding to connect your\nproject and supported editor. Restart your editor after setup.\n\n[What gets installed and indexed?](docs/data-handling.md) ·\n[Supported clients](docs/clients.md) ·\n[Setup guide](https://contextstream.io/docs/editors/setup) ·\n[Prefer to start on the web?](https://contextstream.io/lp/mcp-marketplace?utm_source=github&utm_medium=directory&utm_campaign=mcp_organic_2026q3&utm_content=card_cta)\n\n## Make the next session useful\n\nAsk your connected agent:\n\n> Use ContextStream to find the files relevant to my next change. Cite the\n> sources and retrieve any saved project decisions that should guide the work.\n\nThen ask it to save a real decision and its reason. Start a new session and\nretrieve that decision without explaining it again. Indexing supplies code\ncontext; it cannot recover every undocumented decision.\n\n## Proof and data controls\n\n**95 ms median code search in our published benchmark.** This is the measured\nsuccessful-response median for the disclosed configuration, not a latency guarantee.\n[See results, methodology, and limitations](https://contextstream.io/benchmarks).\n\n**Scoped access. Traceable sources. Configurable capture.**\nIndexing sends eligible source contents to ContextStream for hosted search.\nTranscript saving and local Git metadata capture are on by default and can be\nturned off. Review [data handling and controls](docs/data-handling.md) before\nconnecting sensitive projects.\n\n
