get_apo
AI agents call get_apo 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.
Given the AlphaVantage context (financial data API), the consistent 'get_' naming pattern across all sibling tools, and the absence of any modification or execution keywords, this tool retrieves technical indicator or market data without side effects.
From the tool's definition Tool name 'get_apo' follows the naming pattern of sibling tools like 'get_adx', 'get_aroon', 'get_aluminum', and 'get_balance_sheet_annual', which are all data retrieval functions. The 'get_' prefix consistently indicates read-only retrieval operations.

Register the AlphaVantage MCP Server MCP server in PolicyLayer and add a rule for get_apo: 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_apo 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_apo 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_apo. 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_apo 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.
