Weighted Moving Average (WMA)
AI agents call technicalIndicators_wma 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 mathematical computation on financial data to produce a technical indicator. It reads historical price data and returns a calculated average—a pure analytical operation with no side effects, no data modification, no code execution, and no financial transactions. It belongs in the Read category as a data retrieval and calculation utility.
From the tool's definition Weighted Moving Average (WMA) is a technical analysis calculation that computes a moving average of price data with weights.
Attacks that exploit this kind of access
Weighted Moving Average (WMA). 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_wma: 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_wma 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_wma 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_wma. 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_wma 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.
technicalIndicators_wma is one line of MCP Avantage's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
