About Go Documentation

It helps LLMs understand Go projects by providing direct access to package documentation without needing to read entire source files. godoc-mcp can vastly improve the performance of using LLMs to develop in Go by substantially reducing the number of tokens needed to understand and make use of Go packages.

Features

For directories with Go files: Return package documentation
For directories without Go files: List available Go packages in subdirectories
For import paths: Return standard library or third-party package documentation
Efficient Documentation Access: Retrieves official Go documentation with minimal token usage
Smart Package Discovery: When pointed at a directory without Go files, lists available Go packages in subdirectories
Flexible Path Support:
Automatic Module Context:
Module-Aware: Supports documentation for third-party packages through working directory context (i.e. it will run go doc from the working directory)
Performance Optimized:

Tools (2)

get_doc
