Live endpoint: https://gripp.usefulapi.io/mcp · Homepage: https://usefulapi.io
Connect
- Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste
https://gripp.usefulapi.io/mcp.
- Claude Code:
claude mcp add --transport http gripp https://gripp.usefulapi.io/mcp, then run /mcp to log in.
- VS Code: Add to VS Code.
- Cursor and other clients: add the URL as a remote MCP server:
Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Gripp credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/gripp/
On first connect you provide a Gripp API key (Gripp → Settings → API keys; you must be an application administrator). The server validates it and stores it per user. No keys go in config files.
Tools
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
