Rate of change ratio (ROCR)
AI agents call technicalIndicators_rocr 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 performs a read-only calculation of a technical analysis indicator. It retrieves or derives financial metrics (stock/asset data points) to compute ROCR values, which is used for analysis. No data is created, modified, deleted, or used to execute financial transactions.
From the tool's definition technicalIndicators_rocr computes a technical indicator (Rate of Change Ratio). The tool name and description indicate it retrieves or calculates financial metrics from historical data without modifying any data or executing trades.
Attacks that exploit this kind of access
Rate of change ratio (ROCR). 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_rocr: 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_rocr 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_rocr 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_rocr. 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_rocr 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.
