Documentation Generators

Documentation is a critical component of any successful MCP project. This section will help you choose the right tools for your documentation needs.

​
Overview

Documentation generators for MCP applications are specialized tools designed to create high-quality, interactive documentation that seamlessly integrates with AI assistants. MCP documentation generators can be divided into three main categories:

MCP-Compatible Generators

Specialized tools like Mintlify, Speakeasy, and Stainless that provide features specifically designed for documenting AI-related projects.

GitHub-Powered MCP Docs Servers

Tools like Context7 and GitMCP that turn open-source repositories into MCP servers, allowing AI assistants to access documentation on demand.

Custom Documentation Generators

Build your own MCP documentation server by indexing custom or private documentation using tools like Cloudflare AutoRAG.

​
Why MCP-Specific Generators Matter

MCP-compatible documentation generators offer significant advantages over traditional Retrieval-Augmented Generation (RAG) approaches, particularly concerning context length efficiency.

​
Traditional RAG Limitations

Traditional RAG often involves loading large portions of documentation into the AI’s context window, much of which might be irrelevant to the specific task. This consumes valuable context space and can reduce the AI’s focus.

​
MCP Advantages

In contrast, MCP allows AI agents and IDEs to query specific pieces of information from the documentation server as needed. Instead of pre-loading potentially irrelevant data, the agent retrieves only the necessary details (like API usage, examples, or changelogs) precisely when required.

​
Efficiency Benefits

This targeted retrieval keeps the context window lean and focused, leading to faster and more efficient task completion by the AI assistant. This approach mirrors the benefits seen with systems like the Mastra MCP documentation server, which enables agents to access a complete knowledge base without overwhelming their context.
Using non-MCP-compatible documentation generators may result in less efficient context utilization and degraded AI assistant performance when working with complex projects.

​
Recommendation

For the best results, choose a documentation generator specifically designed to work well with MCP systems and AI assistants. The right documentation tool will significantly enhance your AI assistant’s ability to provide accurate, contextual help to users.
