Add Chappe to Codex

OpenAI, terminal

About 2 minutes. No account yet? It is created when your AI asks you to sign in.

Updated November 2, 2026 by Théo Nairi.

In a terminal, add Chappe:
codex mcp add chappe --url https://chappe.org/mcp
Your browser opens: enter your email, the code you get, then allow it. If it does not open, run:
codex mcp login chappe
Start Codex and type /mcp to check that chappe is connected.

Then, in a new chat, say:

"Open my Chappe inbox"

Good to know

Prefer the file? Add a [mcp_servers.chappe] table with url = "https://chappe.org/mcp" to ~/.codex/config.toml, then run codex mcp login chappe.
The Codex app and the IDE extension share this setup: Chappe shows there too.

Another AI? Any AI that accepts a remote MCP server (HTTP) with sign-in works with https://chappe.org/mcp. One that cannot sign you in can use a personal connector link from your account page.
