Get endpoints list by tag (overview only)
AI agents call get_endpoints_by_tag to retrieve information from OpenAPI Search 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 and filters existing OpenAPI endpoint metadata by tag classification. It performs a query operation with no side effects, data modification, or code execution. The read-only nature and limited scope (documentation queries only) result in low severity — misuse would only expose API structure information that is typically already public via API documentation.
From the tool's definition Tool name 'get_endpoints_by_tag' and description 'Get endpoints list by tag (overview only)' indicate a retrieval operation that queries OpenAPI documentation to return a filtered list of endpoints.

Yes. Add a rate_limit block to the get_endpoints_by_tag 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_endpoints_by_tag. 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.
