Summary
This server connects Claude to WhichModel's model recommendation API, which helps autonomous agents pick the right LLM for each task based on live pricing data. You ask it a question about what model to use, and it returns a single confident recommendation optimized for cost. Useful when you're building agents that need to route requests across multiple models and want to minimize API costs without manually tracking pricing changes. The service limits free queries, so you'll likely need an API key for production use. Exposes streamable HTTP transport, meaning it works with Claude Desktop and other MCP clients that support remote connections.
