Connect Codex

OpenAI's coding agent, with your pod as context.

Directly to your pod

RecommendedExpected to workchecked 1 Sept 2026The client supports what Synap needs; we have not run this path end to end recently.

  1. Install the Synap CLI and sign in.
    npm install -g @synap-core/cli && synap login
  2. Print your pod's MCP URL and an agent key.
    synap mcp url --client codex
  3. Add them to Codex as a remote MCP server (URL + Authorization header) in its config file, ~/.codex/config.toml.

Other ways to connect

With the Synap CLIExpected to workchecked 24 Sept 2026
  1. Install the Synap CLI and sign in.
    npm install -g @synap-core/cli && synap login
  2. Write the client's MCP config and mint a dedicated agent key for your pod.
    synap mcp connect codex
  3. Check the connection any time.
    synap mcp verify

`synap mcp connect codex` wrote ~/.codex/config.yaml, but Codex reads ~/.codex/config.toml. Fixed in the Synap CLI; available in the next release.

If something goes wrong

`synap mcp connect codex` finishes but Codex shows no Synap tools.

Released CLI versions write ~/.codex/config.yaml, which Codex does not read. Until the next release, add the server to ~/.codex/config.toml by hand.

Menus in other apps move; each way to connect shows the day its steps were last checked.
