Read Evenium events, guests, contacts and hotels; register guests and update contacts and statuses. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the Evenium connector, then ask in plain words. The AI picks the tools.
For event teams who manage invitations, guests and attendance in Evenium.
The AI lists the guests of an event by registration status, such as unanswered, confirmed or declined, with name, email and company, so you know whom to remind.
The AI reads the guest's current status and then sets it, for example to confirmed or declined. Changing the status can start the event's own workflows in Evenium.
Changes dataThe AI sets guests to present or no-show after check-in, so your attendance numbers are ready the same day.
Changes dataThe AI searches the address book, creates a missing contact and invites the person to an event as a guest. Invitation emails may follow Evenium's rules for that event.
Changes dataThe AI lists the sessions and workshops of an event and the registrations to one session with their status and attendance.
The AI lists the hotels of an event and the room bookings of a guest with check-in and check-out dates, on accounts where hotels are available.
The login page asks for your Evenium platform and Evenium API key.
Find it in your Evenium profile: My account → API key (Facility accounts on evenium.com), or Profile → API key on the evenium.net platform. The key acts with your account's rights. Your key is used only to call the Evenium API on your behalf; it is never shown to anyone.
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": {
"evenium": {
"url": "https://evenium.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"evenium": {
"type": "http",
"url": "https://evenium.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: the login page asks for your Evenium platform and Evenium 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.
| 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 Evenium server only. Ask your AI to run evenium_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 evenium_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 evenium_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 Evenium. The server calls the Evenium API with your own Evenium 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 Evenium platform and Evenium API key. See Before you connect for where to find them.
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 Evenium platform and Evenium 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.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Evenium 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 Evenium.
Yes, if you approve it. 5 of the 19 Evenium tools can create or change data. The other 14 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
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 Evenium server only. Cancel any time: your paid plan then runs to the end of the paid period. Run evenium_usage_status to see how many calls you used.
Ask the AI to run evenium_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 evenium_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 evenium_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.
