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

MCP Servers First: Always check for existing MCP servers
Official MCP Registry: https://github.com/modelcontextprotocol/servers
NPM Packages: Search @modelcontextprotocol/*
Community MCP: Search GitHub for mcp-server-* repos
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

Understand agency's functionality needs from concept
For each capability needed:
- Search for MCP server first
- Check official registry
- Search npm for @modelcontextprotocol
- Search GitHub for community servers
If MCP found:
- Document server package name
- Note installation command
- List available tools
- Document any configuration needed
- Research API key requirements
If no MCP (rare):
- Research traditional API
- Document endpoints and auth
- Find official documentation for API keys
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
Save findings to agency_name/api_docs.md

Output Format
