About

godoc-mcp

Overview

godoc-mcp is a server that provides information about Go project packages, types, functions, constants, and variables via the Multi-Command Protocol (MCP). It allows you to flexibly retrieve and utilize Go code documentation and structure from external tools.

Main Features

  • Retrieve a list of Go packages
  • List exported structs, functions, and methods in a package
  • Get detailed information about structs (fields, methods, comments)
  • Get detailed information about functions and methods (signature, comments, examples)
  • Get detailed information about constants and variables in a package

Installation

Go 1.24.2 or later is required.

make build

Usage

Start the Server

./godoc-mcp -root
  • Use the -root option to specify the root directory of the Go project to analyze.
  • If omitted, the current directory or the environment variable GODOC_MCP_ROOT_DIR will be used.

Using as an MCP Tool

You can use the following tools from an MCP client:

  • golang_list_packages: Get a list of packages and their comments
  • golang_inspect_package: List structs, functions, and methods in a package
  • golang_get_struct_doc: Get detailed information about a struct
  • golang_get_func_doc: Get detailed information about a function
  • golang_get_method_doc: Get detailed information about a struct method
  • golang_get_const_and_var_doc: Get detailed information about constants and variables
Example: mcp settings for Roo Code

        "GOCACHE": "${env:HOME}/Library/Caches/go-build"
      },
    }
  }
