Common questions

Is FMX MCP by usefulapi safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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.
