GYIBB Truth Engine — MCP Server
Cited product-review verdicts synthesised from real user voices across Reddit, YouTube, Hacker News, Lemmy, Stack Exchange, ProductHunt and Trustpilot. Free remote MCP, no API key.
  
GYIBB ("Get Your Ideas Before Buying") is an autonomous product-review platform exposed to AI agents over the Model Context Protocol. Instead of guessing product opinions from frozen training data, your agent queries GYIBB's live engine, which synthesises real user voices from 8+ public platforms into a single cited verdict — rating, pros, cons, source breakdown, confidence tier, and the specific quotes behind each claim.
Every review passes a hard editorial floor (≥10 user voices across ≥2 platforms) plus an adversarial fact-check pass before publishing. Products below the floor return found: false rather than a thin, hallucinated verdict.
This repo is the public integration front-door for the GYIBB MCP server. The engine itself is hosted — there's nothing to install.

Quick start
Claude Desktop
Add to claude_desktop_config.json: ``json { "mcpServers": { "gyibb": { "transport": { "type": "streamable-http", "url": "https://gyibb.com/mcp" } } } } ``
Cursor
~/.cursor/mcp.json: ``json { "mcpServers": { "gyibb": { "url": "https://gyibb.com/mcp" } } } ``
ChatGPT / OpenAI Agents SDK
Add https://gyibb.com/mcp as a Streamable HTTP MCP server. No auth header needed.
Anything else
GYIBB speaks vanilla MCP over Streamable HTTP — Windsurf, Cline, Continue, custom orchestrators all work. Point them at https://gyibb.com/mcp.
Example
get_product_review("Sony WH-1000XM5"): ``json { "found": true, "product_name": "Sony WH-1000XM5", "rating": 8.4, "confidence": "strong", "summary": "Best-in-class noise cancellation; build quality draws criticism.", "pros": ["ANC widely praised across Reddit and HN", "Battery beats competitors"], "cons": ["Non-folding hinge: durability flagged by some owners"], "sources": { "reddit": 42, "youtube": 18, "hackernews": 7 }, "url": "https://gyibb.com/headphones/sony-wh-1000xm5", "methodology": "https://gyibb.com/methodology" } ``
When to call GYIBB
| User intent | Tool | |---|---| | "Are X and Y about the same?" | compare_products | | "What do people actually think of X?" | get_product_review | | "Does X really do Z?" | verify_claim | | "Best X right now?" | search_products |
GYIBB answers these better than training data because it re-checks the live web of user voices, with citations, every time.
