ConnectOnion 1.9.2b9 (beta)

Install this preview

Stable remains 1.9.1. Install this opt-in beta by exact pin:

python -m pip install --upgrade 'connectonion==1.9.2b9'

Use the connectors Codex already has

co mcp (Experimental) calls the MCP servers and account connectors you already enabled in Codex (Gmail, Google Calendar, GitHub, Vercel, your own servers) from the terminal. It needs no second login and runs no model turn.

co mcp ls                                   # servers, tool counts, auth state
co mcp tools codex_apps                     # one line per tool; read-only ones are marked
co mcp call codex_apps gmail.search_emails '{"query": "newer_than:7d"}'

• co starts codex app-server, opens an ephemeral session (no turn, nothing added to your Codex history), and uses mcpServerStatus/list and mcpServer/tool/call. Codex keeps every credential.
• A read-only tool runs at once and prints its own data as JSON. Any other tool (send, delete, create) prints what it would do and runs only with --yes.
• Claude Code's claude.ai connectors are not called. They are reachable only through a Claude turn; see co mcp.

Measured

On one Mac, 2026-10-11, codex-cli 0.162.1:

Servers listed	6 (codex_apps 537 tools)
gmail.get_profile	3.2 s
gmail.search_emails	1.3 s, with message and thread ids
Same Gmail search through claude -p (Haiku 4.5)	12.2 s, $0.044
New files under ~/.codex/sessions after the runs	0

Verification and limits

• Eight tests against a fake app-server, red before the module existed. The CLI gate suites pass (tips, next steps, cold-start import cost).
• Experimental because Codex marks its app-server protocol experimental; a Codex update can change it.
• Neither Codex nor Claude Code exposes Outlook on the measured machine.
• co rem does not use co mcp for mail yet (#2322).
