## Summary Adds a `/mcp` command to list active tools. We can extend this command to allow configuration of MCP tools, but for now a simple list command will help debug if your config.toml and your tools are working as expected.
codex-protocol
This crate defines the "types" for the protocol used by Codex CLI, which includes both "internal types" for communication between codex-core and codex-tui, as well as "external types" used with codex mcp.
This crate should have minimal dependencies.
Ideally, we should avoid "material business logic" in this crate, as we can always introduce Ext-style traits to add functionality to types in other crates.
