Read reservations, guests and folios; check in reservations and add notes in Rentlio. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the Rentlio connector, then ask in plain words. The AI picks the tools.
For hotel and vacation rental teams that handle arrivals, check-ins and folios in Rentlio.
List the reservations active today at a property, with arrival and departure dates and the unit.
Read one reservation in full, then list its folios with the balances and every charge line.
List the guests checked in at a property between two check-in dates.
List reservations by property, unit, status or date. Give both dateFrom and dateTo, or neither.
Check in a reservation, then add a note such as a late arrival. Both calls change the reservation in Rentlio.
Changes dataThe login page asks for your Rentlio API key and Rentlio property ID.
Create or copy the API key in Rentlio → Account settings → API keys. Find the property ID in Rentlio → Property settings. Your key is used only to call the Rentlio API on your behalf; it is never shown to anyone.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"rentlio": {
"url": "https://rentlio.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"rentlio": {
"type": "http",
"url": "https://rentlio.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
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: the login page asks for your Rentlio API key and Rentlio property ID. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

No. usefulapi is an independent service. It is not affiliated with or endorsed by Rentlio. The server calls the Rentlio API with your own Rentlio access, so it sees only the data that your account can see.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
The login page asks for your Rentlio API key and Rentlio property ID. See Before you connect for where to find them.
No. 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: the login page asks for your Rentlio API key and Rentlio property ID. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Rentlio API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Rentlio.
Yes, if you approve it. 2 of the 10 Rentlio tools can create or change data. The other 8 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls (fair use limit: 10,000 tool calls a month), for this Rentlio server only. Cancel any time: Pro then runs to the end of the paid period. Run rentlio_usage_status to see how many calls you used.
Ask the AI to run rentlio_upgrade: it returns a Stripe Checkout link. To cancel, run rentlio_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with rentlio_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
