get_stoch
AI agents call get_stoch 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.
This tool retrieves the Stochastic Oscillator technical indicator—a calculation based on existing market data with no side effects, data modification, execution of arbitrary code, or financial transactions. The 'get_' prefix and peer tool patterns confirm read-only query semantics. Confidence is slightly reduced due to empty description, but the naming convention and server context are clear indicators.
From the tool's definition Tool name 'get_stoch' follows the naming pattern of sibling tools (get_ad, get_adosc, get_adx, etc.), all of which retrieve financial indicators and market data. The 'get_' prefix indicates data retrieval without modification.

Register the AlphaVantage MCP Server MCP server in PolicyLayer and add a rule for get_stoch: 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_stoch 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_stoch 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_stoch. 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.
