List and create clients, run AML screening checks and read results in ComplyCube. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the ComplyCube connector, then ask in plain words. The AI picks the tools.
For compliance teams that run KYC and AML checks on clients in ComplyCube.
List checks filtered by outcome, such as attention, or by client or status. Open one check to read the outcome of each part.
List clients, newest first, or open one client by id to read its contact and personal or company details.
Create a person or company client, then run a standard or extensive AML screening check. Each check counts against the monthly quota. Read the result later with the check id.
Changes dataThe login page asks for your ComplyCube API key.
Find it in the ComplyCube portal on the Developers → API keys page. Use a test_ key to try the server and a live_ key for real checks. An IP whitelist on your ComplyCube account (Enterprise plan) blocks our shared servers: this page then fails with HTTP 401 or 403. Your key is used only to call the ComplyCube API for you and to derive a private account id; 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": {
"complycube": {
"url": "https://complycube.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"complycube": {
"type": "http",
"url": "https://complycube.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 ComplyCube 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.

No. usefulapi is an independent service. It is not affiliated with or endorsed by ComplyCube. The server calls the ComplyCube API with your own ComplyCube 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 ComplyCube 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 ComplyCube 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 ComplyCube 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 ComplyCube.
Yes, if you approve it. 2 of the 6 ComplyCube tools can create or change data. The other 4 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 ComplyCube server only. Cancel any time: Pro then runs to the end of the paid period. Run complycube_usage_status to see how many calls you used.
Ask the AI to run complycube_upgrade: it returns a Stripe Checkout link. To cancel, run complycube_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 complycube_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.
