Manage members, events and registrations; read invoices, resources and chapters in MemberRun. For associations that manage members, events and registrations in MemberRun. 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": {
"memberrun": {
"url": "https://memberrun.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"memberrun": {
"type": "http",
"url": "https://memberrun.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.
List the active members, then open one member to read its status, role and expiry date.
memberrun_list_members memberrun_get_member
List the events, then list the registrations of one event, filtered by status, to see who is on the waitlist.
memberrun_list_events memberrun_list_event_registrations
List the invoices of one member, filtered by status, then open one to read its amount, currency and due date.
memberrun_list_invoices memberrun_get_invoice
Create a membership for an email address, with a role and status. If the person already has a membership, the API returns HTTP 400.
Changes data · memberrun_list_members memberrun_create_member
Register an existing member for an event. A paid seat is refused unless the ticket was paid on another system, because the API cannot take payment.
Changes data · memberrun_register_member_for_event
The login page asks for your MemberRun API key.
An association admin creates the key in MemberRun under Admin → Integrations. It starts with mk_live_ and is shown only once. Give it only the scopes you need. Your key is used only to call the 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 MemberRun 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.
Turn on the MemberRun connector, then ask in plain words. The AI picks the tools.

memberrun_get_account | read | Get the API key and association Show the association this key belongs to, its name and the key's scopes. Good first call to confirm the connection. API: GET /me. |

memberrun_update_member | write | Update a member Change a member's name, role, status, expiry or profile. Only the fields you send change. Set status to expired to archive. API: PATCH /members/{id}. |
memberrun_suspend_member | write | Suspend a member Suspend a member (soft delete: the status becomes suspended and nothing is erased). Members with admin access cannot be changed through the API. API: DELETE /members/{id}. |
memberrun_create_event | write | Create an event Create an event with a title, type, start time and optional prices and capacity. Prices are whole cents. Creates a real record. API: POST /events. |

memberrun_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. | |
memberrun_request_feature | Request a missing feature Tell usefulapi that the user needs something the MemberRun 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. | |
memberrun_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on MemberRun (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. | |
memberrun_cancel_subscription | Cancel the Pro subscription Cancel the caller's MemberRun 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 memberrun_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 MemberRun server only. Subscribe with memberrun_upgrade (it returns a Stripe Checkout link). Cancel any time with memberrun_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running memberrun_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 MemberRun. The server calls the MemberRun API with your own MemberRun 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 MemberRun API key. 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 MemberRun 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 MemberRun 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 MemberRun.
Yes, if you approve it. 8 of the 21 MemberRun tools can create or change data. The other 13 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 unlimited tool calls (fair use limit: 10,000 tool calls a month), for this MemberRun server only. Cancel any time: Pro then runs to the end of the paid period. Run memberrun_usage_status to see how many calls you used.
Ask the AI to run memberrun_upgrade: it returns a Stripe Checkout link. To cancel, run memberrun_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 memberrun_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.
