AI-generated market sentiment with options flow score (-7 to +7).
AI agents call get_market_pulse to retrieve information from Momentum without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads market sentiment metrics and scoring data without creating, modifying, deleting, or executing any financial transactions or operations. While the server focuses on trading analysis, this particular tool only retrieves computed sentiment indicators and does not commit capital, execute orders, or cause irreversible changes.
From the tool's definition get_market_pulse retrieves and queries AI-generated market sentiment data and options flow scores. The description indicates data retrieval with no modification, deletion, or execution of trades. It is purely analytical.

PolicyLayer is an MCP gateway — it sits between your AI agents and Momentum, and nothing reaches the server without passing your rules. This is the rule we recommend for get_market_pulse:
{
"version": "1",
"default": "deny",
"tools": {
"get_market_pulse": {}
}
}get_market_pulse is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
