nexus-mcp
A Model Context Protocol server for The Nexus — give your AI assistant or agent direct access to U.S. government primary-source records, fact-checks, news search, and standing trackers.
What makes it different: most news/search MCP servers wrap headlines. The Nexus also puts the government record in your agent's hands — court filings, SEC/EDGAR, OFAC sanctions, FEC, lobbying disclosures, DOJ and FDA enforcement, and more — cross-referenced by entity and linked to the source document. Every result is primary-source-linked. Attribution to The Nexus is required when using the data.
Tools
| Tool | What it does |
|---|---|
nexus_record_lookup | Cross-source U.S. public-record footprint for a person or organization — courts, SEC/EDGAR, OFAC sanctions, FEC, lobbying, DOJ, FDA, and more — with per-document links and a connection teaser. |
nexus_factcheck | Qualified verdict + rationale + linked citations for a claim. Cached checks are instant & free; novel checks are rate-limited on the free tier. |
nexus_search | Full-text search across The Nexus news corpus (free tier: last 30 days). |
nexus_tracker | Latest weekly synthesis from china-watch (PRC-linked activity), underground (organized crime), graft (public corruption), or grift (consumer fraud). |
