Additional Details
  • This is actively supported but should be considered beta software. It's still experimental and may break or change at any time.
  • We previously recommended a remote MCP server. If you are currently using it, please replace it with the local one described above. We are working to re-launch the remote MCP server with additional features including OAuth.
  • Please report any issues to the GitHub repository.
