Install JMAP Email in ECA

What you need first

• ECA, installed.
• Docker, which gives the docker command the server starts with.
• Your own values for YOUR_JMAP_SESSION_URL,YOUR_JMAP_AUTH_TOKEN.

Steps

1. Open ~/.codex/config.toml, or create it. The Codex CLI, its IDE extension and the ChatGPT desktop app share this file.
2. Add this table at the end of the file.

{
  "mcpServers": {
    "jmap-mcp": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "JMAP_SESSION_URL", "-e", "JMAP_AUTH_TOKEN", "ghcr.io/mikluko/jmap-mcp:0.10.0"],
      "env": { "JMAP_SESSION_URL": "YOUR_JMAP_SESSION_URL", "JMAP_AUTH_TOKEN": "YOUR_JMAP_AUTH_TOKEN" }
    }
  }
}

3. Replace YOUR_JMAP_SESSION_URL,YOUR_JMAP_AUTH_TOKEN with your own values.
4. Save the file and restart ECA.

Check it worked

Ask ECA: List the tools of jmap-mcp.

If it does not start

Cannot connect to the Docker daemon

Docker is not running. Start it, then restart ECA.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
