Codabench Mcp

Wraps the Codabench REST API so Claude can participate in ML competitions end to end. You get tools to search competitions, read rules and task specs, download datasets with streaming and SHA-256 verification, submit solutions through Codabench's three-step upload flow, poll submission status with backoff, and check leaderboards. Authentication uses a Codabench API token you grab from their Swagger UI or via curl. The generic codabench_request tool is locked to GET by default but you can flip CODABENCH_ALLOW_WRITE_RAW if you need it. Useful when you want Claude to explore benchmarks, prototype submissions, or iterate on a competition without leaving the chat.
