Fact-check claims against live web sources: verdict, consensus, cited sources, PII redaction.
Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Verify a factual claim against multiple live web sources (Brave). Returns a JSON object with a verdict (supported / contradicted / unverified), a 0-1 consensus score, short reasoning, and the actual cited sources (ref, title, url). Judges only from retrieved sources — never fabricates. 'contradicted' is used only when sources actively assert the opposite; absence of evidence yields 'unverified'.
The factual claim to verify against multiple web sources.
How many web sources to consult (default 5, max 10).
