DocGuard MCP server

DocGuard is a tool that checks whether a project's written documentation still matches what the code actually does. It finds things like an endpoint described in the docs that no longer exists, or a section that has drifted out of date. It is handy if you write or maintain docs for a software project and want to catch mistakes before they confuse people.

What this MCP server does

You ask your AI to check the documentation in a project folder. Your AI passes that request to DocGuard through this helper. DocGuard reads the project's docs and code, compares the claims in the docs against what it finds, and produces a list of findings with clear codes. Your AI then shows you those findings in the chat, along with suggested fixes. It only reads; it does not change your files.

What you can do with it

• Check a project's docs against its code and list any mismatches
• Get a maturity score for how complete and consistent the docs are
• See a detailed diagnosis with suggested fixes for each problem found
• Look up one section of a document at a time without loading the whole thing
• Run the same checks your team uses in CI, right from the chat

Try asking your AI

• “Run a DocGuard check on this project and tell me what documentation problems it finds”
• “What is the documentation maturity score for this repo, and what is dragging it down?”
• “Diagnose the docs in this folder and give me the suggested fixes”
• “Show me the API reference section of this project's docs”

What it gives back to you

You get back a list of findings, each with a short code, a plain description, and a suggested fix. You also get a score that summarizes how mature the documentation is, and a diagnosis that groups the issues. Everything shows up as text in your chat, so you can read it and decide what to do next. Nothing in your project is changed.
