MCP server for EZRentOut — rental orders, assets, customers, inventory and work orders. For equipment rental teams with an enabled EZRentOut company API token. Hosted by usefulapi — connect from Claude, ChatGPT, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"ezrentout": {
"url": "https://ezrentout.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"ezrentout": {
"type": "http",
"url": "https://ezrentout.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
Filter rental assets by availability or overdue status and inspect a selected asset and its booked dates.

List work orders and inspect their details before deciding what needs attention.

The login page asks for your EZRentOut subdomain and EZRentOut access token.
The subdomain is the part before .ezrentout.com in the address you sign in at. The token comes from EZRentOut → Settings: the account owner enables API access (for paying accounts) and generates the access token. Your token must permit listing saved custom reports; login checks report metadata only, without exporting a report. Requested rental, asset, customer and report data passes to your chosen AI client and its LLM provider. When requested, tools create customers and orders, book/rent out/return orders, add assets or charges, record payments, add comments, and manage work orders. Recorded payments do not charge cards. Booking, rent-out and return may email customers according to your account settings. Regenerate the token in EZRentOut to stop vendor access. Billing is per company token; rotating it starts a new usage and billing identity.
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 EZRentOut subdomain and EZRentOut access token. 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.
Turn on the EZRentOut connector, then ask in plain words. The AI picks the tools.

Does not count against the meter. | |

For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $39/month or $390/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter. | |
ezrentout_cancel_subscription | Cancel the Pro subscription Cancel the caller's EZRentOut Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run ezrentout_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper company API token | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].

Cancel any time with ezrentout_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running ezrentout_upgrade before then undoes the cancel. Or write to [email protected].

No. usefulapi is an independent service. It is not affiliated with or endorsed by EZRentOut. The server calls the EZRentOut API with your own EZRentOut 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 EZRentOut subdomain and EZRentOut access token. 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 EZRentOut subdomain and EZRentOut access token. 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 EZRentOut 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 EZRentOut.
Yes, if you approve it. 12 of the 59 EZRentOut tools can create or change data. The other 47 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 EZRentOut server only. Cancel any time: Pro then runs to the end of the paid period. Run ezrentout_usage_status to see how many calls you used.
Ask the AI to run ezrentout_upgrade: it returns a Stripe Checkout link. To cancel, run ezrentout_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 ezrentout_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.
