Detect the current structural market regime (Growth, Inflation, Deflation, or Goldilocks).
AI agents call detect_macro_regime 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 is a read-only analytical tool that retrieves and classifies market structure information. It has no side effects, cannot modify any data, and provides informational output for decision-making. Even in a trading context, detection and analysis tools pose minimal risk when misused—the output informs but does not execute trades or move capital.
From the tool's definition Tool performs market regime detection/analysis (Growth, Inflation, Deflation, Goldilocks classification) with no ability to modify data, execute trades, or trigger external operations. The description indicates it 'detects' and 'analyzes' only.
Documented attack patterns abuse exactly the kind of access detect_macro_regime gives an agent:
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 detect_macro_regime:
{
"version": "1",
"default": "deny",
"tools": {
"detect_macro_regime": {}
}
}detect_macro_regime is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Detect the current structural market regime (Growth, Inflation, Deflation, or Goldilocks). It is categorised as a Read tool in the Momentum MCP Server, which means it retrieves data without modifying state.
Register the Momentum MCP server in PolicyLayer and add a rule for detect_macro_regime: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Momentum. Nothing to install.
detect_macro_regime is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the detect_macro_regime rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for detect_macro_regime. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
detect_macro_regime is provided by the Momentum MCP server (mphinance/momentum-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Momentum, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
