QualityScreener

QualityScreener MCP

Give your AI a real stock-screening engine — not a guess. Most assistants will happily invent "stock picks." QualityScreener won't: it connects your AI to a live fundamental-data engine that scores and ranks 40,000+ global equities on returns on capital, profitability, growth, margins, cash generation and balance-sheet strength. Every result is a real, verifiable name with a real score — no hallucinated tickers.

Why it's different

• Real data, zero fabrication. Scores are computed on live fundamentals from the QualityScreener platform, not generated by the model. Ask again tomorrow and the numbers reflect the latest data.
• Acts as you. Connect once via OAuth; the agent works against the same universe and scores you see in the web dashboard.
• Reproducible & shareable. Any screen can be turned into a public, content-addressed link you can drop in a post, report, or DM.

What you can do

• Screen any universe — filter by country, sector, industry, exchange, currency and market cap, then rank it on a custom-weighted quality blend.
• Read the numbers behind each name — ROIC, ROE, gross/operating/FCF margins, earnings stability, valuation and more.
• Build and save reusable scoring systems, then apply them across markets.
• Track a ticker's quality-score history over time.
• Mint a shareable link to any screen.

Quick start

Point your MCP client at the hosted server. On first use, a browser sign-in opens once (you need a free QualityScreener account); after that the agent stays connected.
