get_macd
AI agents call get_macd to retrieve information from AlphaVantage MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
MACD is a read-only technical analysis tool that retrieves precomputed indicator values from financial data. It performs no side effects, modifications, or external operations—purely passive data access. Confidence is lowered slightly (0.92 vs 0.95) due to empty tool description, but server and naming context strongly support Read classification.
From the tool's definition Tool named 'get_macd' with no description; MACD (Moving Average Convergence Divergence) is a standard technical indicator. Sibling tools (get_ad, get_adosc, get_adx, etc.) are all technical indicator getters.
Attacks that exploit this kind of access
get_macd. It is categorised as a Read tool in the AlphaVantage MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AlphaVantage MCP Server MCP server in PolicyLayer and add a rule for get_macd: 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 AlphaVantage MCP Server. Nothing to install.
get_macd 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 get_macd 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 get_macd. 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.
get_macd is provided by the AlphaVantage MCP Server MCP server (lifejwang11/alphavantage-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
