Why it is in this group
- The name "get_market_structure" says "get": a word for reading.
Description, as the server wrote it
The full current SPX dealer market structure, the largest realtime read: walls, gamma flip, net GEX, regime and the strike-level detail below. Current computed SPX dealer market structure (walls, gamma flip, net GEX, regime), recomputed ~every 10s during market hours: scored pressure-point strike ladder, implied 50%/80% forecast-band ranges, strike activity (volume/OI), and VIX term-structure context. Also the 0DTE ATM-straddle expected move and its session fence, max pain, the running session open/high/low with the prior close and gap, order-flow measurements, a top-10 net-GEX strike profile, and chain vanna/charm totals with a top-10 strike ladder. The full realtime structure needs a funded zdte.ai API key (no website account needed); without a key this returns a delayed headline preview (regime, spot, walls, gamma flip, net GEX).

4 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
