Implementation Reference

• src/poetry_mcp/server.py:116-189 (handler)

  The core handler function for the 'search_poems' tool. It performs text search, applies filters for states, forms, and tags, sorts by relevance, limits results, and returns a SearchResult. Registered via @mcp.tool() decorator.
