Route Tool Calls Through an LLM

Let a model decide which tool to invoke.

Let the Model Decide

So far you chose which tool to call. The real power comes when you hand the decision to an LLM, letting the model pick the right tool for a request.

The Bridge Pattern

Your client becomes a bridge: it discovers MCP tools, describes them to the model, and runs whatever tool the model asks for.
