MCP server · live · free while in preview

Give your AI the numbers that matter.

Every finance data feed hands your model raw material — bars, quotes, statements — and the model still can't answer "is this number good?". The Stox MCP server ships context, not data: cross-sectional percentile fingerprints, curated competitive peers, co-movement themes, and market-stress state. Compressed for context windows; provenance on every answer.

Connect it

Works with any MCP client over streamable HTTP. Informational only — it describes, ranks, and cites; it never gives investment advice.

Then ask things like:

  • What's the character of MU right now?
  • Compare Costco to its actual competitors.
  • Who does NVDA trade with, versus who it competes with?
  • Any energy names strong on both price and fundamentals?
  • How stressed is the market today?

This calls the live endpoint from your browser and shows the exact JSON a model receives — with the latency and the token count, because the size of an answer is part of its quality.

the character of one stock. 16 percentile scores vs the S&P 500 cohort, the P3 composite (the validated 3-factor form), curated competitive peers, and a one-line read — ~550 tokens.

The same engine, rendered for humans

Every score these tools serve also powers the editorial leaderboards at stox.market/lists— 31 boards plus sector slices (Technology’s steadiest S&P-beaters, Energy’s cheapest cash flows) and frozen earnings-season editions that never change once published. It works in both directions: a board is where a name catches your eye; fingerprintis how your agent vets it in one call. And if you’d rather the best board of the week come to you, there’s a weekly spotlight email.

What's distinctive

  • Percentiles, not raw numbers. Every score is a rank against the real cohort — the "is 23% gross margin good for a semi?" question answered by construction.
  • True peers. Costco's competitors are Walmart, Target and Kroger — not "Discount Stores". Curated from segment overlap, per company.
  • Token economy. A fingerprint is ~550 tokens where a statements dump is 20,000. Small answers are a feature, not a limitation.
  • Provenance. Snapshot dates on scores, sources and dates on verdicts, and a link back to the full picture on stox.market.

Derived metrics only — this is a judgment layer, not a market-data feed. Descriptive statistics and research citations, never investment advice.
