Sanctions and adverse-media checks from an AI agent: what comes back, and why PEP is not screened

How an assistant screens a person or company through an MCP tool: the sanctions candidates and their strength, the adverse-media hits with evidence, the same-name exclusions, and why PEP is reported as not screened.

How adverse-media and sanctions screening data is collected — the sources, the gaps, and the judgement

Where a screening result actually comes from: four primary sanctions lists taken from the issuers with their own dates, why the UN list and PEP data are absent, how the news layer finds and judges an article, and what a weekly rebuild promises.

How document fraud detection actually works — 43 checks, and why 17 of them are not about fraud

What a forensic document check actually inspects: 43 signals across two axes, why arithmetic beats appearance, and why a clean result is coverage rather than a certificate.

Sanctions and adverse-media screening, for developers who have to justify the result

How a screening API decides a name matches: corroboration gating, why a name-only hit is never strong, what same-name exclusion looks like, and what this data does not cover.
