What it actually does

This Machine-Controlled Program (MCP) provides an interface for AI assistants to access Haskell documentation from Hackage. It allows AI models to retrieve precise, up-to-date documentation for specific Haskell modules, improving the AI's ability to assist with Haskell programming despite limited training data in this domain.

  • Retrieve documentation for specific modules from any package on Hackage
  • Specify exact package versions to ensure accuracy
  • Clean, text-based output that's easily consumable by AI assistants
