List all available API endpoints from the OpenAPI specification
AI agents call list-api-endpoints to retrieve information from OpenAPI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and enumerates available API endpoints from an OpenAPI spec. This is a read-only query operation that does not modify, execute, or delete anything. It has minimal blast radius even if an AI agent invokes it repeatedly or against unintended APIs.
From the tool's definition Tool name is 'list-api-endpoints' and description states it 'List all available API endpoints from the OpenAPI specification' — this is a retrieval operation with no side effects.
Attacks that exploit this kind of access
List all available API endpoints from the OpenAPI specification. It is categorised as a Read tool in the OpenAPI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OpenAPI MCP Server MCP server in PolicyLayer and add a rule for list-api-endpoints: 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 OpenAPI MCP Server. Nothing to install.
list-api-endpoints 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 list-api-endpoints 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 list-api-endpoints. 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.
list-api-endpoints is provided by the OpenAPI MCP Server MCP server (lucivuc/openapi-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
