Common questions

Is resOS 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 (1.1.3) reached the registry yesterday.

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?

In the same category: Spec Driven Development, Remote Desktop Commander, AI Deprecations

resOS MCP by usefulapi

Use your resOS account from Claude, Cursor, or any MCP client. It reads bookings, guests, feedback and availability, and it can create, change or cancel bookings and post guest comments. Hosted, no local install: connect with your own credentials.

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

Connect

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

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

On first connect you provide your resOS API key (Settings → API integration; the API is a paid add-on). The server validates it and stores it per user. No keys go in config files.
