# Fairquery

> Fairquery builds data tools for developers and AI agents: sanctions screening (OFAC, EU, UK, UN), SEC EDGAR data, PII/secret redaction, email validation, website tech/SEO/AI-readiness checks, company contact enrichment and OSV dependency vulnerability checks. Most tools are Apify Actors with a local stdio MCP server; the Agent Trust MCP server bundles several of them.
