Add Rainfrog MCP to Cursor and Claude Code with one URL
Rainfrog is a remote MCP server for image and video campaigns in your studio. How to add it in Cursor and Claude Code, what the official tools cover, and what I checked on the public endpoint.
Rainfrog MCP is a remote server for image and video work in a Rainfrog studio. You add one public URL to a client that supports Streamable HTTP and OAuth, sign in to the Rainfrog account you want the agent to use, and the agent can work with projects, libraries, campaign presets, and canvas workflows. There is no API key to paste into a config file or into chat.
The official setup page is at https://www.rainfrog.ai/mcp. The endpoint is https://mcp.rainfrog.ai/mcp. Rainfrog says connecting has no separate fee, and generation uses the same plan and credit balance as the web studio.
What I checked
I sent an initialize request to that URL with no token. The server answered 401, with invalid_token and a note that the Authorization header was missing. The OAuth protected resource document at https://mcp.rainfrog.ai/.well-known/oauth-protected-resource names the same endpoint as the resource and lists Rainfrog as the resource name. I did not sign in to a Rainfrog account for this writeup, so I did not call the campaign tools myself.
Add it to Cursor
In Cursor, open Settings, then Cursor Settings, then Tools and MCP, add a new MCP server, and use this in mcp.json:
