Envlet for Codex

Codex reads its MCP servers from config.toml. One block adds Envlet, one token gives it an identity.

Set up

  1. 01

    Add the MCP server

    Add the block to ~/.codex/config.toml.

  2. 02

    Give it an identity

    Create an agent identity for Codex in the dashboard or let the migrate prompt do it. Its token opens one environment, and production starts fully withheld.

  3. 03

    Run it through Envlet

    Start Codex with envlet run. It sees the values for its identity and nothing else, and every read shows up under its name.

Questions

Can Codex read production secrets?
Not by default. A new agent grant withholds every current and future production variable. You allow specific names when you decide to.
Do agent identities count toward my plan?
No. Agents and CI identities are unlimited on every plan. Only humans are members.
