Pull exact trivia categories into Claude Desktop

The `get_categories` tool pulls up to 100 trivia categories at a time directly into your local Claude Desktop config. You query the database to build structured lists of topics without leaving your workspace. Once you have the category IDs, you can pass them to other tools to build a full trivia game loop. This runs locally on your machine via stdio transport, giving you zero-latency access to the dataset.

Extract specific trivia categories and clues

The `get_category` tool retrieves a single category and its entire set of associated clues directly inside your Claude Desktop chat window. You get the exact clues, answers, and point values for any specific topic ID. This live data lets your agent generate accurate quiz questions instead of hallucinating outdated facts. The desktop client reads the structured payload directly from the local subprocess, keeping your tests fast and reliable.

Query filtered clues inside this MCP Server

The `get_clues` tool lets you filter the Jeopardy! database by value, category, or date to isolate specific trivia cards. You pinpoint high-value questions or target specific historical air dates to test your model's temporal reasoning. Claude Desktop processes these filtered payloads to evaluate how well your custom prompts handle structured QA formats. Running this through the local MCP server config means your API keys and query parameters stay private on your machine.
