Gyibb Mcp

patheras/gyibb-mcp

Connects Claude (or any MCP client) to GYIBB's product review engine over streamable HTTP with no API key required. Exposes four tools: get_product_review returns cited verdicts with ratings, pros, cons, and source breakdowns from Reddit, YouTube, HN, and others; verify_claim fact checks specific product claims against real user quotes; compare_products runs side by side analysis; search_products filters the catalog by keyword and category. Every review passes a 10+ user voice threshold across multiple platforms before publishing. Reach for this when users ask "what do people actually think" or "is X better than Y" and you want citations instead of training data guesses. Free tier gives you 25 calls per day, 100 with a public integration key.

Readme

GYIBB Truth Engine — MCP Server

Cited product-review verdicts synthesised from real user voices. Free, remote, no API key.

Endpoint: https://gyibb.com/mcp
Transport: streamable-http
Auth: none
Docs for agents: https://gyibb.com/for-agents

Most product "reviews" on the web are marketing copy, affiliate filler, or incentivised ratings. GYIBB reads what actual users said on Reddit, Hacker News, Lemmy, Stack Exchange, ProductHunt, YouTube and Trustpilot, and synthesises it into a structured verdict an agent can act on — with the raw quotes still attached.

Every claim traces back to a source. A product without 10+ user voices across 2+ platforms is refused rather than written up from thin air: an empty answer beats a confident guess.
