zensei
zensei_index_about
What the Zensei Index is, how to read the score, how it is built, and what this server serves (free and Premium). Same wording as the website FAQ. Call it once before interpreting any score.
zensei_index_history
Daily Zensei Index scores for the last `days` calendar days, with the regime of each day. Free access covers the last 31 days; Premium covers up to 3650 days. The Zensei Index is a RISK score from 0 to 100: LOWER IS HEALTHIER. 0-20 Supportive, 20-40 Vulnerable, 40-70 Stressed, 70-100 Restrictive. A rising score means conditions are deteriorating, not improving.
zensei_index_indicators
The ten indicators behind today's Zensei Index, each with its current status, the layer it scores into, its weight in that layer, and the same explanation the website shows. Use it to explain why the index sits where it does. Indicator statuses run from healthiest to most stressed: Clear or Inactive (no stress), Watch (early warning), Stress (confirmed stress), Activated or Danger (full signal). Calibrating means not enough data yet; Unknown means no data.
zensei_index_summary
The latest written summary of the Zensei Index, with the score and regime it was written for. A summary is rewritten only when the indicators change. Check `stale` and `ageDays` before quoting it as today's view, and prefer zensei_index_today for the current number. The Zensei Index is a RISK score from 0 to 100: LOWER IS HEALTHIER. 0-20 Supportive, 20-40 Vulnerable, 40-70 Stressed, 70-100 Restrictive. A rising score means conditions are deteriorating, not improving.
zensei_index_today
Today's Zensei Index for U.S. equities: the final score, its regime label, and the three layer scores (structural conditions, tactical filters, regime confirmations). The Zensei Index is a RISK score from 0 to 100: LOWER IS HEALTHIER. 0-20 Supportive, 20-40 Vulnerable, 40-70 Stressed, 70-100 Restrictive. A rising score means conditions are deteriorating, not improving. Call zensei_index_indicators to see why the score sits where it does.
zensei_my_watchlist
The signed-in user's saved symbols on Zensei, with the sector each one is pinned to. Reads the "Favorites" list unless `list` names another. Needs a Zensei account; custom lists are a Premium feature. Pass each symbol to zensei_stock_detail or zensei_sector_detail for figures.
zensei_search
Find sector ETFs and stocks tracked by Zensei by ticker or name. Returns each stock with the sector ETFs that hold it, largest weight first. Needs Zensei Premium.
zensei_sector_detail
One sector ETF in depth: its quadrant, momentum and returns vs SPY, valuation, and its largest holdings (up to 25). For each holding: weight, quadrant against the sector ETF (not against SPY), momentum, 1-month change and the gap to the sector. The 11 broad S&P 500 sectors (XLK, XLF, XLV, XLE, XLI, XLY, XLP, XLU, XLB, XLRE, XLC) are free; every other sector needs Premium. Get symbols from zensei_sectors_scan.
zensei_sectors_scan
How each sector ETF performs against the S&P 500 (SPY), placed in four quadrants by its 3-month (X) and 1-month (Y) change vs SPY: Outperformers (ahead on both), Emerging (behind over 3 months, ahead over 1 month), Cooling (ahead over 3 months, behind over 1 month) and Underperformers (behind on both). Also gives short-term momentum, relative-strength trend and returns over 1w to 1y. Free access covers the 11 broad S&P 500 sectors; Premium adds 104 thematic and industry sectors. Use zensei_sector_detail for one sector's holdings.
zensei_stock_detail
How one stock performs against a sector ETF that holds it (its 'lens'): returns over 1w to 1y and the gap to the sector, relative-strength trend, valuation, next earnings date, and every tracked sector that holds it with its quadrant there. Without `sector`, the free tier uses a broad S&P 500 sector that holds the stock and Premium uses its largest-weight sector.
zensei_view_indicators
Used by the Zensei Index view to draw the ten indicator charts inside the view. Not for direct use: call zensei_index_indicators instead.
zensei_view_sector
Used by the Zensei sector map view to open one sector's holdings inside the view. Not for direct use: call zensei_sector_detail instead.

Zensei Index — questions
Answers built from our own checks of this server.

It exposes 12 tools, read directly from the server on our last check. Among them: zensei_index_about, zensei_index_history, zensei_index_indicators, zensei_index_summary, zensei_index_today, zensei_my_watchlist and 6 more.

How MCP servers expose tools in the first place →
Is Zensei Index working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 223 ms. The bar chart above shows every period we have measured.
How do I connect Zensei Index?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Zensei Index need an API key?
No. Zensei Index completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 12 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Zensei Index?
It answers our handshake in 223 ms on average, which is faster than 61% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Zensei Index open source?
The code is open source: it is published under the MIT licence, written in Shell and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at zensei.com, which runs on its operator's own terms.
