Read events, programmes, speakers, registration orders, tickets and attendance in eventOne. For event organizers who publish programmes, speakers and registrations in eventOne. 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": {
"eventone": {
"url": "https://eventone.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"eventone": {
"type": "http",
"url": "https://eventone.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.
Read the event, then list its days, timeslots and sessions to see the programme by day and time.
eventone_get_event eventone_list_days eventone_list_timeslots eventone_list_sessions
List the speakers with their titles and featured flags, and the tracks with their colours, for one event.
eventone_list_speakers eventone_list_tracks
List the registration orders filtered by status or date range, and list the promo codes with their limits and expiry.
eventone_list_registration_orders eventone_list_promos
Search events by text across the platform, then list the events of one organization by its slug.
eventone_search_events eventone_list_orgs eventone_list_events
Get the recorded headcount for each session of an event, and list the rooms with their capacity.
eventone_get_event_attendance eventone_list_rooms
The login page asks for your eventOne personal access token.
Create one on your eventOne account page under Personal access tokens. Your token is used only to call the eventOne API on your behalf 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 eventOne personal access token. 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 eventOne connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
eventone_get_me | read | Get my account Return the signed-in eventOne user (id, name, email, company). Good first call to confirm the token works. |

eventone_get_org | read | Get an organization Get one organization by id or by slug (give one of them). |

eventone_get_event | read | Get an event Get one event by id, or by event slug together with its organization slug. |
eventone_search_events | read | Search events Search events by text across the platform. Returns matching events with their ids. |
eventone_list_days | read | List event days List the days of an event's programme. |

eventone_list_promos | read | List promo codes List the promo codes of an event with discount, status, limit and expiry. |
eventone_list_registration_orders | read | List registration orders List the registration orders of an event, one page at a time. Contains attendee personal data. Filter by status (draft, pending, rejected, complete, refunded) or created date range. |
eventone_list_tickets | read | List tickets List the tickets of an event, or only those of one order. Contains attendee names and emails. |
eventone_list_people | read | List people List the people (contacts) of an organization, one page at a time, with an optional search. Contains personal data. |

eventone_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. | |
eventone_request_feature | Request a missing feature Tell usefulapi that the user needs something the eventOne 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. | |
eventone_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on eventOne (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. | |
eventone_cancel_subscription | Cancel the Pro subscription Cancel the caller's eventOne 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 eventone_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 eventOne server only. Subscribe with eventone_upgrade (it returns a Stripe Checkout link). Cancel any time with eventone_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running eventone_upgrade before then undoes the cancel. Or write to [email protected].
Build the programme of an event. List the speakers and tracks. Check registration orders and promo codes. Find an event and its organization. Review session attendance. See what you can do for the details.
No. usefulapi is an independent service. It is not affiliated with or endorsed by eventOne. The server calls the eventOne API with your own eventOne 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 eventOne personal access token. See Before you connect for where to find it.
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 eventOne personal access token. 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 eventOne 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 eventOne.
All 20 eventOne 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 eventOne server only. Cancel any time: Pro then runs to the end of the paid period. Run eventone_usage_status to see how many calls you used.
Ask the AI to run eventone_upgrade: it returns a Stripe Checkout link. To cancel, run eventone_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 eventone_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.
