A: Hello, thanks for reaching out! Yes, the TidyCal MCP server isn't limited to Claude. Web apps need to be on our approved list (Claude.ai is), but desktop apps that finish the sign-in on your own computer, through a localhost or 127.0.0.1 address, are accepted without being added to any list. OpenCode, which OpenWork is built on, signs in this way.

To connect, add https://tidycal.com/mcp as a remote MCP server in OpenWork, then sign in to TidyCal and approve access when the browser opens. You'll need a paid TidyCal plan (Individual, Agency or Pro), and the connection is read-only: the assistant can look up your bookings, booking types and availability, but it can't change anything.

If the sign-in step is rejected, please email [email protected] with the exact error message. You're also welcome to request OpenWork support at https://tidycal.com/feedback.
