List all Moleculer events
AI agents call moleculer_list_events to retrieve information from Moleculer MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that enumerates available events in the Moleculer microservices architecture. It has no side effects—it merely provides information about the system state. Listing/discovery operations are classified as Read. The blast radius is minimal since an agent cannot cause harm by simply viewing event definitions.
From the tool's definition Tool name 'moleculer_list_events' and description 'List all Moleculer events' indicate a query/list operation that retrieves event metadata without modification or execution.
Attacks that exploit this kind of access
List all Moleculer events. It is categorised as a Read tool in the Moleculer MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Moleculer MCP Server MCP server in PolicyLayer and add a rule for moleculer_list_events: 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 Moleculer MCP Server. Nothing to install.
moleculer_list_events 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 moleculer_list_events 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 moleculer_list_events. 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.
moleculer_list_events is provided by the Moleculer MCP Server MCP server (moleculerjs/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
