What you can do with Momence in Claude and ChatGPT

For fitness and wellness studio owners and front-desk staff who run classes and memberships in Momence.

See the class schedule and how full each class is

The AI lists scheduled sessions (classes, events, courses) in a date window with time, teacher, location, capacity and booking count. You see which classes are full or empty.

Check who is booked into a class

The AI lists the roster of one session with each booking's member and check-in state. It can also show the waitlist size from the session details.

Look up a member's bookings and memberships

The AI finds a member by name, email or phone, then lists their class bookings and their active memberships with dates, credits left and freeze state.

Review sales leads and membership plans

The AI lists leads by source or pipeline stage, and the membership plans the studio sells with pricing, duration and credits. You can see open leads and what you offer.

Check in, book, waitlist or cancel a class spot

The AI checks a booking in or out, books a member into a session as a comp booking, adds them to a waitlist, or cancels one booking. A cancel can refund and notify the member.

How do I connect Momence?

Before you connect

The login page asks for your API client id, API client secret, Staff email and Staff password.

Your client id, client secret, email and password are stored encrypted in this connection's authorization grant and used only to sign in to Momence and call the Momence API on your behalf. They are never shown to anyone; the client id and email are also hashed into a private account id for usage metering.

Claude claude.ai · Desktop

Open Customize → Connectors, then click + Add → Add custom connector.
Enter the name Momence and this URL, then click Add:
https://momence.usefulapi.io/mcp
Claude opens the login page: enter your API client id, API client secret, Staff email and Staff password.
In a chat, click + → Connectors and turn on Momence.

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 Momence and this URL, choose OAuth as the authentication, confirm the warning and create it:
https://momence.usefulapi.io/mcp
ChatGPT opens the login page: enter your API client id, API client secret, Staff email and Staff password.
In Plugins, install Momence, 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 momence https://momence.usefulapi.io/mcp

Cursor

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

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

VS Code

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

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

Codex

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

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

codex mcp login momence

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://momence.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 client id, API client secret, Staff email and Staff password. 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 Momence server only. Ask your AI to run momence_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 momence_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 momence_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4

Usage status (free-tier meter)momence_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 featuremomence_request_feature
Tell usefulapi that the user needs something the Momence 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+momence_upgrade
Get a paid plan for Momence (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 subscriptionmomence_cancel_subscription
Cancel the caller's Momence 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 momence_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Momence in Claude or ChatGPT?

See the class schedule and how full each class is. Check who is booked into a class. Look up a member's bookings and memberships. Review sales leads and membership plans. Check in, book, waitlist or cancel a class spot. See what you can do for the details.

Is this an official Momence product?

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

Can I connect Momence 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 client id, API client secret, Staff email and Staff password. See Before you connect for where to find them.

Do I put my Momence 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 client id, API client secret, Staff email and Staff password. 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 Momence credentials?

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

Can the AI change my Momence data?

Yes, if you approve it. 7 of the 23 Momence tools can create or change data. The other 16 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 Momence server only. Cancel any time: your paid plan then runs to the end of the paid period. Run momence_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run momence_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 momence_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Momence tool that I need is missing?

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