What you can do with Hello Club in Claude and ChatGPT
For gym, sports club and community club managers who run memberships and bookings in Hello Club.
Find members who owe money
The AI lists members with their amount owing and account credit, and lists transactions by paid state. You can total what is outstanding.
See upcoming events and classes and who signed up
The AI lists events and classes in a date range with capacity and attendance rules, and lists who signed up, with paid state and whether they attended.
Check court, room and lane bookings
The AI lists resource bookings with owner, activity, area, start and end and paid state, filtered by date range, member or area.
Review who checked in and door access logs
The AI lists check-ins with who, when and how, and door access logs in a date range. You can see who came to the club.
Add a member, a charge or a credit
The AI creates a new member, or creates a charge or credit on a member's account. A charge changes the member's amount owing.
Changes dataHow do I connect Hello Club?
Before you connect
The login page asks for your Hello Club API key.
Create it in Hello Club under Integrations → API keys (the card at the bottom of the page; API access needs the Business plan). A key has full access to your club's data, so use a key made just for this connection and switch it off in Hello Club to revoke it. Your key is used only to call the Hello Club API on your behalf; it is never shown to anyone.

Claude Code
Run this command, then run /mcp in Claude Code to log in:
Cursor
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"hello-club": {
"url": "https://hello-club.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"hello-club": {
"type": "http",
"url": "https://hello-club.usefulapi.io/mcp"
}
}
} Codex
Run these commands. The second one opens the login page:
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.
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 Hello Club 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 club | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per club | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this Hello Club server only. Ask your AI to run hello_club_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 hello_club_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 hello_club_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

- Create member
hello_club_create_memberWRITE: create a new member in the club (first and last name required; email, mobile, phone and gender optional). Creates a real member record in the club's database; it does not assign a membership or send an invoice. Not idempotent: calling twice creates two members, so search with hello_club_list_members first. - Create transaction
hello_club_create_transactionWRITE: create a financial transaction for a member (a charge, or a credit when is_credit is true), e.g. an invoice line or a manual adjustment. This changes the member's amount owing / account credit in the club's books and, with notify_by_email, emails the member. Not idempotent: calling twice creates two transactions. Confirm member, amount and type with the user first.
Your usefulapi plan · 4
- Usage status (free-tier meter)
hello_club_usage_statusReport 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 feature
hello_club_request_featureTell usefulapi that the user needs something the Hello Club 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+
hello_club_upgradeGet a paid plan for Hello Club (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 subscription
hello_club_cancel_subscriptionCancel the caller's Hello Club 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 hello_club_upgrade later to undo the cancel before the period ends. Does not count against the meter.
FAQ
What can I do with Hello Club in Claude or ChatGPT?
Find members who owe money. See upcoming events and classes and who signed up. Check court, room and lane bookings. Review who checked in and door access logs. Add a member, a charge or a credit. See what you can do for the details.
Is this an official Hello Club product?
No. usefulapi is an independent service. It is not affiliated with or endorsed by Hello Club. The server calls the Hello Club API with your own Hello Club access, so it sees only the data that your account can see.
Can I connect Hello Club 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 Hello Club API key. See Before you connect for where to find it.
Do I put my Hello Club 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 Hello Club 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 Hello Club credentials?
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Hello Club 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 Hello Club.
Can the AI change my Hello Club data?
Yes, if you approve it. 2 of the 14 Hello Club tools can create or change data. The other 12 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 Hello Club server only. Cancel any time: your paid plan then runs to the end of the paid period. Run hello_club_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run hello_club_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 hello_club_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a Hello Club tool that I need is missing?
Tell the AI what you wanted to do. It can send the request with hello_club_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.
