Real-time fact-check, citation verification, and source-freshness for AI agents.
Real-time fact-check, citation verification, and source-freshness for AI agents.
Hosted MCP server that fact-checks an LLM's claims and citations in real time. Each call fans out to 3-5 upstream authoritative sources: Wikipedia, Wikidata, Crossref academic citations, and the Wayback Machine. Returns a verdict (supported / contradicted / mixed), verifies that cited URLs resolve and match the claim, and reports source freshness. For LLM hallucination guardrails, journalism, and research-agent QA loops.
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
