GoDevMCP

What is GoDevMCP?

GoDevMCP is a Model Context Protocol (MCP) server that provides development tools with a focus on Go, and additional support for Rust and Python. It offers documentation lookup, code search, project navigation, and more. Intended for developers using MCP-compatible clients like Claude Code or VS Code.

How to use GoDevMCP?

Install via go install github.com/fpt/go-dev-mcp/godevmcp@latest or build from source. Then configure an MCP client to run the godevmcp serve command. For example, add to VS Code settings.json under "mcp"."servers", or run claude mcp add godevmcp -s user godevmcp serve for Claude Code.

Use cases of GoDevMCP

• Look up Go package documentation during development without leaving the editor

• Navigate and inspect local or GitHub repository structures quickly
• Search across file contents in local directories or GitHub codebases

FAQ from GoDevMCP

Does GoDevMCP require authentication for all tools?

No. GitHub authentication is required only for the GitHub tools (code search, content, diffs, issues, pull requests, workflow runs). Go, Rust, and Python doc tools, directory tree, local search, outline, markdown, and validation work without it.

How does GoDevMCP resolve a GitHub token?

It checks the GITHUB_TOKEN or GH_TOKEN environment variable first. If neither is set, it falls back to the locally installed and authenticated gh CLI (gh auth login).

What runtime is required to run GoDevMCP?

The server is a compiled Go binary; no runtime beyond the operating system is needed. To install it from source, Go is required.

Which MCP clients are supported?

GoDevMCP uses the stdio transport and can be used with any MCP‑compatible client. Setup examples are provided for Claude Code and VS Code.

Does GoDevMCP search local files only or also remote?

It supports both: local directory searches via search_local_files and tree_dir, and remote GitHub searches via search_github_code, get_github_content, and tree_github_repo.
