Use Codex and the ChatGPT Desktop App with Your Email

Set it up

1. Open Postage, then Settings > Agents, and turn on Let agents connect to Postage.
2. Under Codex, press Add Postage to Codex and pick your ~/.codex/config.toml when asked. Postage adds one [mcp_servers.postage] entry, keeps everything else in the file, and saves a backup first.
3. Restart Codex, then ask it to list your Postage accounts. The Codex row in Postage turns green when it connects.

If you'd rather add it by hand, this is the entry (Postage fills in your real token):

[mcp_servers.postage]
url = "http://127.0.0.1:47913/mcp"
http_headers = { "Authorization" = "Bearer YOUR_POSTAGE_TOKEN" }
tool_timeout_sec = 600

tool_timeout_sec = 600 gives you time to review a message Codex prepared: compose tools wait for you to press Send or close the window.

What about ChatGPT's connectors?

Postage's server runs only on your Mac, at 127.0.0.1. Add it through Codex's config file as above, not through ChatGPT's connector settings.

Things to ask

• "What did Stripe email me about this month?"
• "Archive every newsletter older than two weeks, across both accounts."
• "Draft replies to everyone waiting on me."
• "Find the PDF contract Dana sent in August."

Codex can read, search and organize at the access level you set. Anything it writes opens in a Postage compose window for you to send.
