nexus-mcp
MCP server providing access to U.S. government primary-source records, fact-checks, news search, and trackers, with cross-referenced entity data and source links.
README
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.
