MCP Servers
Kaizen supports Model Context Protocol (MCP) servers for extending its capabilities with external tools and data sources.
Context7
Context7 is a built-in MCP integration that provides version-specific documentation for 9,000+ libraries and packages. It helps the Developer agent write better code by giving it access to accurate, up-to-date API docs.
How It Works
Two tools are available:
context7-resolve: Resolves a library name to its Context7 ID
Input: library name (e.g., "react", "next.js")
Output: ranked list of matching libraries with versions and trust scores
context7-docs: Fetches documentation for a specific library
Input: library ID, query, optional topic and token limit
Output: relevant code examples and API documentation
Configuration
Context7 works out of the box with no configuration required. Optionally, set a CONTEXT7_API_KEY environment variable for higher rate limits.
Usage
The Developer agent automatically uses Context7 when it needs library documentation. It prefers Context7 over web-fetch for API docs because the results are structured, version-specific, and more reliable.
Adding MCP Servers
MCP is an open protocol. Any MCP-compatible server can potentially be integrated with Kaizen. The Zapier integration, for example, uses MCP under the hood to discover and call Zapier actions.
