Overview

AI-generated overview

A remote MCP server that gives an assistant modeled options dealer-positioning levels — gamma flip, call and put walls, max pain and net dealer gamma — for SPX,

What you can do
Retrieve modeled dealer-positioning levels for one underlying: gamma flip, call wall, put wall, max pain, same-day pin strike and net dealer gamma at spot, whose sign indicates the regime (get_gamma_levels). Get a one-line positioning summary for all six covered underlyings (SPX, SPY, QQQ, NDX, ES, NQ) in a single call, with spot, modeled regime and gamma flip for each (get_market_gamma_overview). Answer questions such as where the gamma flip or the walls are, whether an index is in positive gamma, or which indices are in negative gamma.
When to use it
Useful when you want an assistant to discuss options dealer positioning for major US indices — locating gamma flips and walls, checking the current regime, or getting a quick overview across all covered underlyings before a market session.
Requirements
A remote MCP endpoint at zerogex.io over streamable HTTP; no authentication, environment variables or headers are declared, so no account or API key appears to be needed. Network access to the endpoint is required.
Before you install
The data is explicitly free and delayed (at least a delay is stated), so it is not suitable for real-time trading decisions. The levels are modeled estimates of dealer positioning, not observed positions, and cover only six underlyings. No credentials are requested, but queries are sent to a third-party service.

Installation

In SourceWeft

  1. Open ZeroGEX — SPX/SPY/QQQ/NDX dealer positioning in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.zerogex%2Fgamma-levels/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.

get_gamma_levels

Get delayed gamma levels

Modeled options dealer-positioning levels for one underlying: gamma flip, call wall, put wall, max pain, same-day pin strike, and net dealer gamma at spot (whose sign is the regime). Use for "where is the gamma flip", "where are the walls", "is SPX in positive gamma". FREE DELAYED DATA - at least 15 minutes behind live, and the response states its own age; quote that age and never call these levels live. Not a price feed, not a forecast, and not a trade recommendation: it describes dealer positioning and says nothing on its own about direction. A null level means the modeled book does not support that level right now - report it as unavailable, never as zero.

Parameterssymbolrequired

get_market_gamma_overview

Get delayed gamma levels for every symbol

One-line dealer-positioning summary for all six covered underlyings (SPX, SPY, QQQ, NDX, ES, NQ) in a single call: spot, modeled regime and gamma flip for each. Use for broad openers like "what does dealer positioning look like today" or "which indices are in negative gamma", instead of calling get_gamma_levels six times. Same free 15-minute-delayed data and the same caveats. When the question is about one symbol, call get_gamma_levels instead - this tool omits the walls, max pain and pin strike.

Takes no parameters.
