Install Overlap — find a time a group is free (when2meet/Doodle alternative) in Kiro

What you need first

• Kiro, installed.
• Nothing else: the server runs on its publisher's machines and Kiro connects to it.

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": {
    "group-scheduling-when2meet": {
      "url": "https://overlap.notdown-app.workers.dev/mcp"
    }
  }
}

3. Save the file and restart Kiro.

Check it worked

Ask Kiro: List the tools of group-scheduling-when2meet.

If it does not start

401 Unauthorized

The endpoint wants a sign-in or a key. Sign in when Kiro asks.

Nothing changes after a restart

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