get_kama
AI agents call get_kama 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.
Based on the sibling tools and naming convention, this tool retrieves a financial technical indicator value from the AlphaVantage API. This is a read-only operation that queries data without modification, deletion, or execution of arbitrary logic. Confidence is moderate (0.7) rather than high because the description is empty, but the naming pattern and server context provide strong contextual evidence.
From the tool's definition Tool name 'get_kama' follows the naming pattern of sibling tools (get_ad, get_adosc, get_adx, etc.) which are all technical indicator retrieval functions. KAMA is a well-known technical indicator (Kaufman's Adaptive Moving Average).
Attacks that exploit this kind of access
get_kama. 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_kama: 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_kama 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_kama 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_kama. 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_kama 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.
