Obtain intraday data for one or multiple stock tickers.
AI agents call get_intraday_data to retrieve information from Marketstack 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 historical or real-time intraday pricing data for stocks. It performs no writes, deletes, executes code, or financial transactions. The blast radius of misuse is minimal—an agent might retrieve excessive data or query repeatedly, but cannot cause harm beyond potential rate-limiting or data exposure concerns. This is a standard Read operation.
From the tool's definition Tool name 'get_intraday_data' and description 'Obtain intraday data for one or multiple stock tickers' indicate data retrieval with no modification or execution of external operations.

get_intraday_data 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_intraday_data 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_intraday_data. 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.
