Use Orca from Codex

Codex CLI talks to Orca through the same MCP server the CLI ships.

Setup

Install the CLI and sign in once:

curl -fsSL https://orcapods.ai/install.sh | sh
orca login

Then register the server in ~/.codex/config.toml:

[mcp_servers.orca]
command = "orca"
args = ["mcp", "serve"]

The tool surface is identical across clients: golden-path tools plus the api_request escape hatch. See The Orca MCP server for the full table.
In fully headless environments, skip the login flow and export ORCA_API_KEY before launching Codex; the server picks it up per call. See Headless authentication.
The orca CLI itself is also agent-friendly if you prefer shelling out: every command takes --json, streaming commands emit NDJSON, and exit codes are stable (0 ok, 1 failure, 2 usage, 3 auth, 4 not found).
