Hilbert Transform - Trend vs Cycle Mode
AI agents call technicalIndicators_htTrendmode to retrieve information from MCP Avantage without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a technical indicator calculation tool that analyzes and returns financial data insights. It reads market data and applies a mathematical transformation (Hilbert Transform) to provide analysis output. There are no side effects, data modifications, external executions, deletions, or financial commitments involved. This is purely a Read operation—retrieving and computing metrics from existing financial data.
From the tool's definition The tool 'technicalIndicators_htTrendmode' performs a Hilbert Transform analysis to classify trend vs cycle modes.
Attacks that exploit this kind of access
Hilbert Transform - Trend vs Cycle Mode. It is categorised as a Read tool in the MCP Avantage MCP Server, which means it retrieves data without modifying state.
Register the MCP Avantage MCP server in PolicyLayer and add a rule for technicalIndicators_htTrendmode: 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 MCP Avantage. Nothing to install.
technicalIndicators_htTrendmode 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 technicalIndicators_htTrendmode 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 technicalIndicators_htTrendmode. 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.
technicalIndicators_htTrendmode is provided by the MCP Avantage MCP server (missionsquad/mcp-avantage). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
