The sanctionlistcheck.com MCP server screens names against 10 official sanctions lists. We fetch these lists every day from official sources into a versioned snapshot. Each screening creates a record with a unique record id, which can be fetched again later.

Server URL: https://sanctionlistcheck.com/mcp · Transport: Streamable HTTP

Tools

screen_names	Screen Names Sanctions screening of 1 to 100 names against 10 official lists. The response includes a record id, the snapshot version, the data-as-of date for each source list, and the matching engine version. Each screened name costs one credit. Hits are candidates for human review and require further assessment.

list_sources	List Source Lists The list_sources tool provides the 10 official sanctions lists and their data-as-of dates from the current daily snapshot. This tool is free to use and does not require an API key.
get_balance	Get Credit Balance Retrieve the credit balance for your API key and its latest credit movements. This tool is free to use.

API Key

All tool calls, except for list_sources, require an API key sent in the Authorization Bearer header. Request a key by sending a POST request to the /v1/keys endpoint with your email address; the key will arrive by email. A new key includes 100 free credits, and each screened name costs one credit.
