Research MCP servers and APIs for Agency Swarm v1.0.0 tool implementation, strongly prioritizing MCP servers.

## Background
MCP (Model Context Protocol) servers are the preferred integration method in Agency Swarm v1.0.0. They provide:
- Standardized tool interfaces
- No custom code maintenance
- Automatic tool discovery
- Built-in error handling
- Community support and updates

## Research Priority
1. **MCP Servers First**: Always check for existing MCP servers
2. **Official MCP Registry**: https://github.com/modelcontextprotocol/servers
3. **NPM Packages**: Search `@modelcontextprotocol/*`
4. **Community MCP**: Search GitHub for `mcp-server-*` repos
5. **Custom APIs Last**: Only if no MCP server exists

## Known MCP Servers
Common MCP servers to check for:
- `@modelcontextprotocol/server-filesystem` - File operations
- `@modelcontextprotocol/server-github` - GitHub integration
- `@modelcontextprotocol/server-gitlab` - GitLab integration
- `@modelcontextprotocol/server-slack` - Slack integration
- `@modelcontextprotocol/server-postgres` - PostgreSQL
- `@modelcontextprotocol/server-sqlite` - SQLite
- `@modelcontextprotocol/server-memory` - Memory/knowledge base
- `@modelcontextprotocol/server-puppeteer` - Web automation
- `@modelcontextprotocol/server-brave-search` - Web search
- `@modelcontextprotocol/server-fetch` - HTTP requests

## Process
1. Understand agency's functionality needs from concept
2. For each capability needed:
   - Search for MCP server first
   - Check official registry
   - Search npm for @modelcontextprotocol
   - Search GitHub for community servers
3. If MCP found:
   - Document server package name
   - Note installation command
   - List available tools
   - Document any configuration needed
   - Research API key requirements
4. If no MCP (rare):
   - Research traditional API
   - Document endpoints and auth
   - Find official documentation for API keys
5. **Research how to obtain each API key**:
   - Find official signup/documentation pages
   - Note free tier availability
   - Document exact steps to get keys
   - Include any approval wait times
6. Save findings to `agency_name/api_docs.md`

# Output Format
Create `agency_name/api_docs.md`:
```markdown
# API Documentation for [Agency Name]
