What bookings do I have tomorrow, and for which customers?
How many visits did we have last week, bookings and walk-ins?
What are the first free appointment slots for the haircut service?

What you can do with Waitwhile in Claude and ChatGPT

For business owners and front-desk staff who run waitlists and bookings with Waitwhile.

See who is waiting and the current wait time

The AI reads the live status of locations with open or closed state, people waiting and being served, and the estimated wait. It can also list the visits in line.

Review today's bookings and find a visit

The AI lists visits (waitlist entries and bookings) and can search by customer name, phone, email or customer id, filtered by location, state or tag.

Find the first open appointment slots

The AI lists booking slots for a location and date range, or the first available slots from a date, optionally for a party size, services and resources. You can propose times to a customer.

Report visits, bookings and no-shows for a period

The AI reads visit statistics for a period: visits, waitlisted, bookings, served, no-shows, cancellations and wait durations, with breakdowns by location, resource and service.

Add, update or cancel a visit, or add a customer note

The AI adds a customer to the waitlist or creates a booking, changes a visit's state, tags or time, cancels a visit, or adds a staff note to a customer.

How do I connect Waitwhile?

Before you connect

The login page asks for your Waitwhile API key.

Create it in Waitwhile → Settings → Developers → API & Webhooks → Create API key (the API needs the Business plan or higher). Your key is used only to call the Waitwhile API on your behalf; it is never shown to anyone.

Claude claude.ai · Desktop

Open Customize → Connectors, then click + Add → Add custom connector.
Enter the name Waitwhile and this URL, then click Add:
https://waitwhile.usefulapi.io/mcp
Claude opens the login page: enter your Waitwhile API key.
In a chat, click + → Connectors and turn on Waitwhile.

Team and Enterprise: an Owner adds the connector for the organization first.

ChatGPT chatgpt.com

Open Plugins, click +, then Add custom MCP server.
Enter the name Waitwhile and this URL, choose OAuth as the authentication, confirm the warning and create it:
https://waitwhile.usefulapi.io/mcp
ChatGPT opens the login page: enter your Waitwhile API key.
In Plugins, install Waitwhile, 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 waitwhile https://waitwhile.usefulapi.io/mcp

Cursor

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

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

VS Code

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

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

Codex

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

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

codex mcp login waitwhile

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://waitwhile.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 Waitwhile 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.

Pricing

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

Each paid plan covers this Waitwhile server only. Ask your AI to run waitwhile_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 waitwhile_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 waitwhile_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Add a customer to the waitlist or create a bookingwaitwhile_create_visit
WRITE: create ONE visit at a location. Without a date it adds the customer to the waitlist; with a local date-time (YYYY-MM-DDThh:mm) it creates a booking. Needs a location and at least a name, phone or e-mail. Not idempotent: calling it twice creates two visits. Visit notes are not supported here (the field is deprecated): use waitwhile_add_customer_note. By default the request asks Waitwhile to suppress the customer message; this may only stop the immediate confirmation, and scheduled reminders/follow-ups can still go out per the location's settings. With send_notifications=true Waitwhile may text/e-mail this ONE customer.
Update a visit (state, tags, time, party)waitwhile_update_visit
WRITE: change ONE visit — its state (e.g. WAITING to SERVING to COMPLETE, or BOOKED), add/remove tags (e.g. ARRIVED, CONFIRMED, NO-SHOW), booking date/duration or party size. Only the fields you pass change. By default the request asks Waitwhile to suppress the customer message; this may only stop the immediate status message, and scheduled reminders/follow-ups can still go out per the location's settings. With send_notifications=true Waitwhile may text/e-mail this ONE customer. Use waitwhile_cancel_visit to cancel.
Cancel a visitwaitwhile_cancel_visit
WRITE: cancel ONE visit (a waitlist entry or booking). Waitwhile sets its state to COMPLETE and adds the CANCELLED tag; the visit is kept, not deleted. By default the request asks Waitwhile to suppress the customer message; this may only stop the immediate cancellation notice, and scheduled reminders/follow-ups can still go out per the location's settings. With send_notifications=true Waitwhile may text/e-mail this ONE customer.
Add a customer notewaitwhile_add_customer_note
WRITE: add one staff note to a customer's record (optionally tied to a visit and location). Adds only; nothing is edited or sent to the customer.

Your usefulapi plan · 4

Usage status (free-tier meter)waitwhile_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 featurewaitwhile_request_feature
Tell usefulapi that the user needs something the Waitwhile 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+waitwhile_upgrade
Get a paid plan for Waitwhile (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 subscriptionwaitwhile_cancel_subscription
Cancel the caller's Waitwhile 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 waitwhile_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Waitwhile in Claude or ChatGPT?

See who is waiting and the current wait time. Review today's bookings and find a visit. Find the first open appointment slots. Report visits, bookings and no-shows for a period. Add, update or cancel a visit, or add a customer note. See what you can do for the details.

Is this an official Waitwhile product?

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

Can I connect Waitwhile 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 Waitwhile API key. See Before you connect for where to find it.

Do I put my Waitwhile 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 Waitwhile 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.

How do you keep my Waitwhile credentials?

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

Can the AI change my Waitwhile data?

Yes, if you approve it. 4 of the 29 Waitwhile tools can create or change data. The other 25 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 Waitwhile server only. Cancel any time: your paid plan then runs to the end of the paid period. Run waitwhile_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run waitwhile_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 waitwhile_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Waitwhile tool that I need is missing?

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