Zensei MCP server

The MCP server for Zensei: the Zensei Index and the sector rotation scan, in Claude, ChatGPT and any MCP client.

The Zensei Index is a 0-100 risk score for the US stock market. Lower is healthier. The sector scan compares every US sector ETF with the S&P 500.

Interactive views

In apps that support MCP Apps (Claude, ChatGPT), two tools come with a view:

• zensei_index_today shows the regime card. Expand it to see the full dashboard, with each indicator's chart.
• zensei_sectors_scan shows the rotation map. Expand it to see the rankings, and open a sector to see its holdings.

The views call two app-only tools, zensei_view_sector and zensei_view_indicators. Apps hide them from the model.
