What it is
A documentation lookup service for coding agents, offered as an MCP server and a command-line tool. It fetches version-specific library docs and code examples into the agent's context on request.
Who it might suit
Developers whose coding agent gives outdated or invented API answers and who want current library documentation pulled into prompts.
What to check first
The project disclaims accuracy, completeness and security of the community-contributed library docs it serves. Its API backend, parsing and crawling engines are private, setup uses OAuth and an API key, and the MCP endpoint is a hosted URL.
