Go Documentation MCP server
by mrjoshuak
Lets your AI read Go package documentation without opening whole source files, so answers come faster and cheaper.
This is a small helper program that gives your AI a way to look up Go documentation on your own computer. It is made for people who write or read Go code and want their AI to understand a project without pasting in piles of files. If you have never touched Go, this one is probably not for you.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you using what you paste in or what it already knows. An MCP server is a small helper program that gives your AI one extra skill, in this case the ability to read Go documentation. Once it is connected, your AI can ask this helper about a Go package, a type, or a function, and the helper fetches just that piece of documentation. That means your AI gets the right details without you having to copy entire source files into the chat.
What this MCP server does
You ask your AI something about a Go package, like what a type does or which methods it has. Your AI passes that request to this helper program running on your machine. The helper runs the standard Go documentation tool behind the scenes and grabs only the part you asked about. It sends that back to your AI, which then explains it to you in the chat. Because it only pulls the relevant piece, it uses far fewer tokens than reading whole files.
Click to zoomWhat you can do with it
- Look up documentation for any Go package, type, function, or method
- List all the exported names in a package so you can see what is available
- Show the full source of a single function or type when you need the details
- Discover which sub-packages live under a package path
- Read documentation for third-party packages your project already uses
- Explore an unfamiliar Go project and get a summary of what each package does
Try asking your AI
- “What interfaces does the io package provide, especially anything about reading?”
- “Show me the documentation for the Server type in the /path/to/project/server package.”
- “I need to implement the io.Reader interface. Show me its docs and related types.”
- “I'm in /path/to/some/project which uses github.com/gorilla/mux. Show me the Router type.”
What it gives back to you
You get back a short, focused answer in the chat: documentation text, a list of names, or the source of one item. It is not a file you download, just readable text your AI can explain or summarize. Sometimes it comes in pages if the result is long, and your AI can ask for the next page.
Before you start
What you need
- Go installed on your computer (the go command must work)
- The godoc-mcp program installed, usually with one go install command
- An MCP client that can run local servers, like the Claude desktop app or Claude Code
Good to know
It only reads documentation and source on your machine, so it does not change or delete anything, but it can see any Go files in the folders you point it at.
Install it with your AI
Add Go Documentation MCP server to your AI, no technical skills needed
You don't install anything by hand. You copy one prompt, paste it into an AI that can work on your computer, and it checks, installs and connects the server for you, asking you when it needs something.
Sign in to get the install prompt
Members get a ready-made prompt that lets the Claude desktop app check Go Documentation MCP server, install it and connect it for them, step by step. You don't need any technical skills: you copy, paste and answer a few questions. Your connected AI can also find and install any of the 4,066 MCP servers here for you.
Who it's for
Go developers and anyone reading or writing Go code who wants their AI to understand a project without pasting in whole files.
