Hilbert Transform - Instantaneous Trendline
AI agents call technicalIndicators_htTrendline 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 tool retrieves or calculates technical indicator values from financial data—a read-only analytical operation. It does not create, modify, delete, execute code, or involve financial transactions. The blast radius of misuse is minimal; incorrect trendline calculations affect only analysis outputs, not actual market positions or data integrity.
From the tool's definition Tool name 'technicalIndicators_htTrendline' and description 'Hilbert Transform - Instantaneous Trendline' indicate a technical analysis calculation that retrieves or computes a mathematical indicator based on historical price data.
Attacks that exploit this kind of access
Hilbert Transform - Instantaneous Trendline. 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_htTrendline: 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_htTrendline 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_htTrendline 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_htTrendline. 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_htTrendline 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.
