api

Deterministic; returns findings (masked), counts, and a redacted copy. Use before logging/forwarding untrusted or agent-generated text. Costs $0.005 per call.

screening

Sanctions Screening — questions

Answers built from our own checks of this server.

What can Sanctions Screening do?

It exposes 13 tools, read directly from the server on our last check. Among them: check_jurisdiction, create_api_key, create_watch, get_screening_info, kyb_check, list_watches and 7 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Sanctions Screening working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 141 ms. The bar chart above shows every period we have measured.

The registry lists Sanctions Screening as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Sanctions Screening?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Sanctions Screening need an API key?

No. Sanctions Screening completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 13 of them are readable on this page. This is what we observed, not what the docs claim.

Is Sanctions Screening open source?

We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
