Read events, ticket types, orders, attendees and daily ticket sales in Universe. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the Universe connector, then ask in plain words. The AI picks the tools.
For event organizers who sell tickets with Universe.
List your events, or the events of a host account you manage. Ask the assistant for a summary of tickets sold per event.
List the ticket types of an event with price, capacity and sold count. Find the types that need a reminder or a new batch.
Read the ticket sales per day for an event between two dates. Ask the assistant to show the trend before and after a promotion.
List the orders and the attendees of an event. Filter by order state or by name. Open one order to see the buyer and the check-in state.
List the time slots of an event with capacity and tickets sold. Filter by a date range to see which dates still have room.
You sign in with your Universe account and approve the access (OAuth). You do not need an API key.
This server reads your events, ticket types, orders, attendees and sales. It does not change anything. You can revoke access any time in your Universe account settings.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"universe": {
"url": "https://universe.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"universe": {
"type": "http",
"url": "https://universe.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
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: you sign in with your Universe account. 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.
| 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 Universe server only. Ask your AI to run universe_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 universe_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 universe_upgrade before then undoes the cancel. Or write to [email protected].

No. usefulapi is an independent service. It is not affiliated with or endorsed by Universe. The server calls the Universe API with your own Universe 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.
A Universe account. You sign in to Universe and approve the access. You do not need an API key.
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: you sign in with your Universe account. 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 Universe 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. You can revoke the access in Universe at any time.
All 9 Universe tools are marked read-only.
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 Universe server only. Cancel any time: your paid plan then runs to the end of the paid period. Run universe_usage_status to see how many calls you used.
Ask the AI to run universe_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 universe_cancel_subscription. Your paid plan continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with universe_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.
