Swiss Truth MCP

Verified knowledge base for AI Agents — certified Swiss facts, no hallucinations. Swiss Truth gives your AI agent access to a curated, expert-reviewed knowledge base — covering Swiss law, health, finance, education, energy, politics, climate, AI/ML, and world science. Every fact has passed a 5-stage validation pipeline: semantic deduplication, AI pre-screening, source URL verification, expert peer review, and SHA256 integrity signing. Confidence scores decay over time — no stale data silently served. Tools included: • search_knowledge — semantic search in DE, EN, FR, IT, ES, ZH (auto-detected) • verify_claim — fact-check any statement → supported / contradicted / unknown • submit_claim — contribute new facts through the full validation pipeline • get_claim, list_domains, get_claim_status No API key required. Fully public. Connect in 30 seconds.
