Gopls Go Language Server

What is Gopls Go Language Server?

Gopls Go Language Server is an MCP (Model Context Protocol) server that wraps the official Go language server, gopls, to expose its features through MCP. It is intended for developers who want to interact with Go code using MCP clients such as Claude Code or Claude Desktop.

How to use Gopls Go Language Server?

Install it with go install github.com/yantrio/mcp-gopls/cmd/mcp-gopls@latest, then add it to an MCP client. For Claude Code, run claude mcp add mcp-gopls "$(which mcp-gopls)". For Claude Desktop, add the executable to claude_desktop_config.json under mcpServers. Launch the server with mcp-gopls; you can optionally specify a gopls binary path and workspace directory via flags or environment variables.

FAQ from Gopls Go Language Server

What are the runtime requirements?

Go 1.24.3 or later and the official gopls language server are required. Install gopls with go install golang.org/x/tools/gopls@latest.

How do I specify a custom workspace or gopls path?

Use the -workspace and -gopls flags, or set the environment variables MCP_GOPLS_WORKSPACE and GOPLS_PATH respectively.

What transport protocol does this server use?

The README only describes command-line invocation; this is consistent with an MCP server using stdio transport. No other transports are mentioned.

Is the code safe for production use?

The README includes a strong warning that the entire project was generated by AI without human code review. It advises extreme caution in production environments and notes that security, performance, and edge cases have not been audited.
