AI agents call list_api_endpoints to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a read-only operation that enumerates API endpoint metadata. There are no side effects, no code execution, no data modification, and no destructive actions. This is clearly a retrieval/query operation with minimal risk if misused by an AI agent, as it only exposes available endpoint information.
From the tool's definition Tool is named 'list_api_endpoints' and described as 'List all Swagger path entries.' This is a query/listing operation that retrieves information about available API endpoints from Swagger/OpenAPI documentation without modifying, executing, or deleting any…

List all Swagger path entries. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the 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 Mcp. 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 MCP server (victormyschik/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
