FMX MCP by usefulapi

FMX MCP by usefulapi

Use your FMX account from Claude, Cursor, or any MCP client. Read-only access to buildings, equipment, inventory, resources, attachments and users in your tenant. Hosted, no local install: connect with your own credentials.

Live endpoint: https://fmx.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://fmx.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http fmx https://fmx.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:

{
  "mcpServers": {
    "fmx": {
      "url": "https://fmx.usefulapi.io/mcp"
    }
  }
}

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 FMX credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/fmx/

On first connect you provide your FMX tenant (the acme part of acme.gofmx.com), the API user email and the API user password of a dedicated API user. Create an API user type under Admin Settings → User Types, then create the user under Users. The server validates them and stores them per user. No keys go in config files.
