The nexus-mcp server provides AI agents with direct access to U.S. government primary-source records, fact-checks, news search, and standing trackers via The Nexus platform.

• nexus_record_lookup — Look up the public-record footprint of a person or organization across multiple U.S. government sources, including courts, SEC/EDGAR, OFAC sanctions, FEC records, lobbying disclosures, DOJ and FDA enforcement actions, and more — with per-document links.

• nexus_factcheck — Fact-check any plain-language claim against The Nexus's news corpus and public records. Returns a qualified verdict (e.g., Supported, Misleading, Contradicted), a rationale, a confidence level, and linked citations. Cached checks are instant; novel checks are rate-limited on the free tier.

• nexus_search — Full-text search across The Nexus news and government feed corpus, returning source-linked articles sorted newest first. The free tier covers the last 30 days, with a configurable result limit (up to 50).

• nexus_tracker — Retrieve the latest weekly synthesis from one of four standing trackers: china-watch (PRC-linked activity), underground (organized crime), graft (public corruption), or grift (consumer fraud & scams).
