Expose Codex itself as an MCP server
mcp & extensions
// what it does
codex mcp-server runs Codex itself as a stdio MCP server, so another MCP client — an IDE or another agent — can call Codex as a tool. This is the inverse of codex mcp add, and it is currently experimental.
// shell
$ codex mcp-server// gotcha
mcp-server (Codex as a server) is not the same as mcp add (Codex as a client). Don't point Codex at its own mcp-server expecting the add flow.
