Search members, memberships and saved searches; update contact fields in MemberSuite. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the MemberSuite connector, then ask in plain words. The AI picks the tools.
For associations that track members, memberships and event sign-ups in MemberSuite.
Search the individuals who joined this month, then search their memberships for the type, join date and benefit status.
Run an MSQL query on the event registrations of one event, to read the names and the waitlist status of each registrant.
List the public saved searches with their IDs, then run one of them to read its records.
Find the individual by ID, then update only the fields that changed, such as the email address or phone number. Test writes in a Sandbox first.
Changes dataThe login page asks for your Tenant ID (Association Key), API user email and API user password.
Find the Tenant ID (Association Key) in the MemberSuite Console → Setup → Association Settings. The API user is a dedicated account that MemberSuite (GrowthZone) issues on request for API access. Your password is used only to log in to the 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": {
"membersuite": {
"url": "https://membersuite.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"membersuite": {
"type": "http",
"url": "https://membersuite.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 Tenant ID (Association Key), API user email and API user 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.
| 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 MemberSuite server only. Ask your AI to run membersuite_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 membersuite_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 membersuite_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 MemberSuite. The server calls the MemberSuite API with your own MemberSuite 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 Tenant ID (Association Key), API user email and API user password. See Before you connect for where to find them.

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the MemberSuite 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 MemberSuite.
Yes, if you approve it. 1 of the 7 MemberSuite tools can create or change data. The other 6 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 MemberSuite server only. Cancel any time: your paid plan then runs to the end of the paid period. Run membersuite_usage_status to see how many calls you used.
Ask the AI to run membersuite_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 membersuite_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 membersuite_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.
