Cardzen maintains guided setup for ChatGPT and Claude. Other technical clients can connect with the generic MCP details below.
Requirements
Your client must support:
- Remote MCP servers over Streamable HTTP
- MCP authorization discovery and browser-based OAuth
- HTTPS server addresses
Connection Details
- Transport: Streamable HTTP
- Server address:
https://mcp.cardzen.ai/mcp - Authentication: OAuth discovered from the Cardzen MCP resource
Add the remote server, allow the client to perform authorization discovery, and complete Cardzen sign-in and approval in the browser. Do not paste a Firebase token, Cardzen session credential, or manually created bearer token into the client.
Cardzen does not maintain client-specific field names or screenshots beyond ChatGPT and Claude. Consult your client's documentation to map its remote-server fields to the details above.
See MCP Privacy and Security and MCP Limits and Troubleshooting before diagnosing the connection as a Cardzen failure.
