Read rooms, rates, inventory, reservations and price quotes in ThinkReservations. For hotels, inns and rental properties that manage bookings in ThinkReservations. 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": {
"thinkreservations": {
"url": "https://thinkreservations.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"thinkreservations": {
"type": "http",
"url": "https://thinkreservations.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.
List the reservations with a stay date in a date range. Add the guest contact details if the API key has the customer scope.
thinkreservations_list_reservations
Read the daily inventory per room type for a date range. List the room types first to get their ids. Use the numbers to plan sales.
thinkreservations_list_room_types thinkreservations_get_inventory
Search what the property can sell for given dates and guests. Read the price per rate type with fees, taxes, deposit and total. The quote books nothing.
thinkreservations_get_availability
Read the day-by-day price, minimum stay and closed-to-arrival rules of a rate type. Compare them with the active promotions of the property.
thinkreservations_list_rate_types thinkreservations_get_daily_rates thinkreservations_list_promotions
List the reservations that changed since a given time. Use the result to update a report or sheet without a full export.
thinkreservations_list_reservations
List the blackouts in a date range. See which rooms are blocked on which dates before you promise a room to a guest.
thinkreservations_list_blackouts thinkreservations_list_rooms
The login page asks for your Hotel ID and Restricted API key.
Create the key in ThinkReservations → Settings → API Keys (you need the “Can manage API keys” permission). The same page shows your hotel ID. Grant only the read scopes you need; add read:hotel so the key can be checked. Your key is used only to call the API for you and to derive a private account id; it is never shown to anyone.
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 Hotel ID and Restricted API key. 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 ThinkReservations connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
thinkreservations_get_hotel | read | Get property details Get the basic details of the property (hotel) the API key is bound to. Needs scope read:hotel. |
thinkreservations_list_rooms | read | List rooms List the rooms of the property: name, description, room type and whether the room is active. Needs scope read:room. |
thinkreservations_list_room_types | read | List room types List the room types (name and id). Use the ids to filter inventory and daily rates. Needs scope read:room. |
thinkreservations_list_rate_types | read | List rate types List the rate types the property offers, with their policies. Needs scope read:rate. |
thinkreservations_get_rate_type | read | Get rate type Get one rate type and its policies by id. Needs scope read:rate. |
thinkreservations_get_daily_rates | read | Get daily rates Get the day-by-day price, minimum-stay rules and closed-to-arrival restrictions of one rate type for a date range. Needs scope read:rate. |
thinkreservations_list_promotions | read | List promotions List the promotions configured for the property. Needs scope read:rate. |
thinkreservations_list_reservations | read | List reservations List reservations (paged). Filter by stay dates, creation time or last-modified time (give at least one filter). Guest contact details appear only if the key has scope read:customer; otherwise customer is null. Needs scope read:reservation. |
thinkreservations_get_inventory | read | Get inventory Get the daily inventory (units left) per room type for a date range. Needs scope read:availability. |
thinkreservations_list_blackouts | read | List blackouts List the blackouts in a date range: room-specific blocked dates (room id and date pairs), not whole-property closures. Needs scope read:availability. |
thinkreservations_get_availability | read | Get availability and prices Search what the property can sell for a stay: per bookable unit, the rate types with price for the whole stay, fees, taxes, deposit and total. Read-only quote, books nothing. Needs scope read:availability. |
thinkreservations_usage_status | Usage status (free-tier meter) 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. | |
thinkreservations_request_feature | Request a missing feature Tell usefulapi that the user needs something the ThinkReservations 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. | |
thinkreservations_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on ThinkReservations (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. 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. | |
thinkreservations_cancel_subscription | Cancel the Pro subscription Cancel the caller's ThinkReservations 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 thinkreservations_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 user | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this ThinkReservations server only. Subscribe with thinkreservations_upgrade (it returns a Stripe Checkout link). Cancel any time with thinkreservations_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running thinkreservations_upgrade before then undoes the cancel. Or write to [email protected].
See which guests arrive next week. Check open units by room type for a month. Quote a stay with fees, taxes and deposit. Review rates, restrictions and promotions. Sync changed reservations to a spreadsheet. Find blocked dates for single rooms. See what you can do for the details.
No. usefulapi is an independent service. It is not affiliated with or endorsed by ThinkReservations. The server calls the ThinkReservations API with your own ThinkReservations 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 Hotel ID and Restricted API key. 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 Hotel ID and Restricted API key. 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 ThinkReservations 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 ThinkReservations.
All 11 ThinkReservations tools are marked read-only.
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 ThinkReservations server only. Cancel any time: Pro then runs to the end of the paid period. Run thinkreservations_usage_status to see how many calls you used.
Ask the AI to run thinkreservations_upgrade: it returns a Stripe Checkout link. To cancel, run thinkreservations_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 thinkreservations_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.
