What it does

Chooses which discovered MCP tool Codex should call, then applies deterministic policy before execution.

How you can use it

If your assistant connects to dozens of tools, giving it every tool at once can cause confusion. You can have a developer add this router between the assistant and your tools. The router keeps the full list hidden until the assistant actually asks for a specific job.

When the assistant asks for help, the router checks the request against the names and descriptions of available tools. If it is very sure of a match, it hands over just that one tool. If it is uncertain, it provides a shortlist to choose from.
