GYIBB Truth Engine — free MCP for product reviews
GYIBB synthesises real user voices from Reddit, Hacker News, Lemmy, Stack Exchange, ProductHunt, YouTube and Trustpilot into cited, structured product verdicts. Instead of guessing from frozen training data, your agent queries a live engine that grounds every claim in real quotes.
Every review passes a hard editorial floor — ≥10 user voices across ≥2 platforms plus an adversarial fact-check — before publishing. Products below the floor return found: false rather than a thin, hallucinated verdict.
