Fiix MCP by usefulapi
Use your Fiix account from Claude, Cursor, or any MCP client. It reads work orders, assets, purchase orders and accounts, and it changes nothing. Hosted, no local install: connect with your own credentials.
Live endpoint: https://fiix.usefulapi.io/mcp · Homepage: https://usefulapi.io
Connect
- Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste
https://fiix.usefulapi.io/mcp.
- Claude Code:
claude mcp add --transport http fiix https://fiix.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 Fiix credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/fiix/
On first connect you provide your Fiix subdomain (the part before .macmms.com), an Application Key, an Access Key and a Secret Key. A Fiix administrator creates the keys under Settings → Connect Management → Fiix API Application Settings, and the API needs a Fiix Enterprise plan. The server validates them and stores them per user. No keys go in config files.
