Overview

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.

Endpoint

  • URL: https://gyibb.com/mcp
  • Transport: Streamable HTTP
  • Auth: none (free, no API key). Optional public key we-read-it-so-you-dont raises the per-IP daily quota from 25 to 100 tool calls.

Tools

  • get_product_review(query) — full verdict: rating, confidence, pros, cons, sources, citation links
  • verify_claim(product_slug, claim) — fact-check a claim → supported / contradicted / mixed / insufficient_data with evidence
  • compare_products(slugs[]) — side-by-side comparison of up to 5 products
  • search_products(query, category?, limit?) — rating-sorted catalogue search

Zhipu Web SearchZhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
