List available API endpoints
AI agents call list_endpoints to retrieve information from MCP Server Templates without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays metadata about API endpoints. It performs a read-only operation that discovers available services without modifying, executing, or deleting anything. The blast radius is minimal—an agent could learn what endpoints exist, but cannot misuse this information to cause direct harm without invoking those endpoints separately.
From the tool's definition Tool name 'list_endpoints' and description 'List available API endpoints' indicate a query/retrieval operation that returns information about available endpoints with no side effects.
Attacks that exploit this kind of access
List available API endpoints. It is categorised as a Read tool in the MCP Server Templates MCP Server, which means it retrieves data without modifying state.
Register the MCP Server Templates MCP server in PolicyLayer and add a rule for list_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 Server Templates. Nothing to install.
list_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_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_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_endpoints is provided by the MCP Server Templates MCP server (visystems/mcp-server-templates). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_endpoints is one line of MCP Server Templates's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
