What you can do with Avirato in Claude and ChatGPT

For small hotels and guesthouses that run their front desk, rates and bookings in Avirato.

Check tomorrow's arrivals and departures

List the reservations between two dates to see who checks in and who checks out. Open a reservation to read the guest, the room and the outstanding amount.

Find a room and quote the price of a stay

Check availability for the dates. Then get the price of the stay for a room type, a rate and the number of guests, and compare the rates the hotel offers.

Review the price calendar and discounts

Read the price of each day for a period and the discounts that apply to room types and rates. Check the minimum-stay rules before you confirm a quote.

Trace a booking from a sales channel

List the booking channels, then get a reservation by the channel's booking id. Read the other rooms of a group booking in the same view.

Record a cash payment on a booking

Read the booking to check the outstanding amount. The assistant confirms the booking id and the amount with you, then records the cash payment. Card payments are not supported.

How do I connect Avirato?

Before you connect

The login page asks for your API user email, API user password and Establishment code (webCode).

Create a dedicated API user in Avirato: Menú → Configuración → Mi cuenta → Usuarios y seguridad, new user with its own email, tick only API, save, confirm the verification email and set its password. The establishment code is the number at the end of the link from Configuración → Canales de venta → Motor de reservas → Generador de enlaces. Your login is stored encrypted and used only to call the Avirato API on your behalf; it is never shown to anyone. Avirato limits requests per source IP: after a wrong password wait a moment before retrying.

In Plugins, install Avirato, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http avirato https://avirato.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

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

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "avirato": {
      "type": "http",
      "url": "https://avirato.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add avirato --url https://avirato.usefulapi.io/mcp

codex mcp login avirato

Other clients

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.

https://avirato.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: the login page asks for your API user email, API user password and Establishment code (webCode). 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.

Pricing

Plan	Price	Limit
Free	$0	50 tool calls / month
Proper user	$9/mo · $90/yr	10,000 tool calls / month
Pro+per user	$39/mo · $390/yr	100,000 tool calls / month

Each paid plan covers this Avirato server only. Ask your AI to run avirato_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with avirato_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with avirato_upgrade before then undoes the cancel. Or write to [email protected].

Record a cash payment on a bookingavirato_add_booking_cash_payment
WRITE: records a cash payment on an existing booking in the hotel's PMS (it changes the booking's paid and outstanding amounts and cannot be undone through this server). Not idempotent: calling it twice records two payments. Confirm the booking id and the amount with the user first, then pass confirm: true. If the call fails with a network error or timeout the payment may still have been recorded: read the booking (avirato_get_reservation) and check its payments before trying again. Card payments are not supported.

Your usefulapi plan · 4

Usage status (free-tier meter)avirato_usage_status
Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
Request a missing featureavirato_request_feature
Tell usefulapi that the user needs something the Avirato tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
Upgrade to Pro or Pro+avirato_upgrade
Get a paid plan for Avirato (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
Cancel the Pro subscriptionavirato_cancel_subscription
Cancel the caller's Avirato 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 avirato_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Avirato in Claude or ChatGPT?

Check tomorrow's arrivals and departures. Find a room and quote the price of a stay. Review the price calendar and discounts. Trace a booking from a sales channel. Record a cash payment on a booking. See what you can do for the details.

Is this an official Avirato product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Avirato. The server calls the Avirato API with your own Avirato access, so it sees only the data that your account can see.

Can I connect Avirato to Claude or ChatGPT?

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.

What do I need to connect?

The login page asks for your API user email, API user password and Establishment code (webCode). See Before you connect for where to find them.

Do I put my Avirato key or an Authorization header in the client config?

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 API user email, API user password and Establishment code (webCode). 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.

How do you keep my Avirato credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Avirato 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 Avirato.

Can the AI change my Avirato data?

Yes, if you approve it. 1 of the 23 Avirato tools can create or change data. The other 22 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Avirato server only. Cancel any time: your paid plan then runs to the end of the paid period. Run avirato_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run avirato_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run avirato_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Avirato tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with avirato_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.

Which AI clients can I use?

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.
