Analyze revenue by product — shows each product
AI agents call get_product_performance to retrieve information from Indie Metrics without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries business metrics from Stripe (similar to sibling tools like get_revenue_summary and get_revenue_forecast) and presents aggregated revenue performance data by product. It is a read-only analytical query that retrieves existing data without creating, modifying, or deleting records.
From the tool's definition Tool retrieves and analyzes revenue metrics grouped by product. The verb 'analyze' and 'shows' indicate data retrieval and reporting with no modification. Description contains no language suggesting write, delete, or execute capabilities.
Attacks that exploit this kind of access
Analyze revenue by product — shows each product. It is categorised as a Read tool in the Indie Metrics MCP Server, which means it retrieves data without modifying state.
Register the Indie Metrics MCP server in PolicyLayer and add a rule for get_product_performance: 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 Indie Metrics. Nothing to install.
get_product_performance 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_product_performance 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_product_performance. 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_product_performance is provided by the Indie Metrics MCP server (marccherggi/indie-metrics-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
