Tool of verification-mcp

declared in 0.1.0

Verify a factual claim against authoritative sources (Wikipedia, Wikidata, Crossref academic citations). Returns a verdict ('supported' / 'contradicted' / 'mixed' / 'unverified'), a 0–1 confidence score, and the list of sources with excerpts. Use this when an agent is about to assert a fact it isn't 100% sure of, or when post-processing LLM output to flag possibly-hallucinated claims.
