YARD Documentation
Exposes Ruby gem and YARD documentation through 11 specialized tools for exploring classes, methods, and inheritance hierarchies with fuzzy search, source code retrieval, and automatic documentation building for Ruby development workflows.
About
This MCP server exposes Ruby gem and YARD documentation as programmable tools, built by Roman Shterenzon using Ruby with the fast-mcp gem and YARD documentation system. The implementation builds a comprehensive index of all installed gems with YARD documentation at startup, then provides 11 specialized tools for exploring classes/modules/methods, fetching documentation with parameters and return types, performing fuzzy search across docstrings, retrieving source code snippets, and analyzing inheritance hierarchies and relationships. Built with intelligent gem loading that caches the last loaded .yardoc file to avoid unnecessary reloads, Levenshtein distance-based fuzzy search, and automatic documentation building for gems without existing YARD docs, it serves Ruby developers needing AI-assisted code exploration, teams building documentation browsers or code assistants, and applications requiring programmatic access to Ruby gem documentation through conversational interfaces.
