Install Comunio in Claude Desktop

What you need first

• Claude Desktop, installed.
• Docker, which gives the docker command the server starts with.
• Your own values for YOUR_COMUNIO_USERNAME,YOUR_COMUNIO_PASSWORD.

Steps

1. In Claude Desktop, open Settings › Developer and choose Edit Config. It opens claude_desktop_config.json.
2. Add this block. If the file already has mcpServers, add only the entry inside it.

{
  "mcpServers": {
    "comunio": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "COMUNIO_USERNAME", "-e", "COMUNIO_PASSWORD", "ghcr.io/josetorronteras/comunio-mcp:1.0.2"],
      "env": { "COMUNIO_USERNAME": "YOUR_COMUNIO_USERNAME", "COMUNIO_PASSWORD": "YOUR_COMUNIO_PASSWORD" }
    }
  }
}

3. Replace YOUR_COMUNIO_USERNAME,YOUR_COMUNIO_PASSWORD with your own values.
4. Save the file, quit Claude Desktop completely and open it again.

Check it worked

Ask Claude Desktop: List the tools of comunio.

If it does not start

Cannot connect to the Docker daemon

Docker is not running. Start it, then restart Claude Desktop.

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.
