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).

Setup

Get a free, email-verified API key at https://thenexus.news/developers.
Install: npm install -g @thenexusintel/mcp (or clone and npm install).
Add the server to your MCP client.

}

(Or point command/args at a local node /path/to/server.js.)

Free tier

Unlimited record / search / tracker calls and unlimited cached fact-checks; a small number of novel fact-checks per day. Higher volume and entity-graph depth are on the paid tier — see /developers.

Environment

Var	Required	Default
`NEXUS_API_KEY`	yes	—
`NEXUS_API_BASE`	no	`https://thenexus.news`

Security note: only set NEXUS_API_BASE to a host you trust — it's where your key is sent. Leave it unset to use The Nexus.
