find_event_types
AI agents call find_event_types to retrieve information from EMS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool is used to discover or retrieve event type information from the Event Monitoring System, consistent with read-only data retrieval operations. Empty description reduces confidence slightly, but the naming pattern and context of other read-only list/query tools strongly suggest this is a retrieval operation with no side effects.
From the tool's definition Tool name 'find_event_types' and sibling tools (list_event_profiles, list_databases, list_ems_systems, query_database, query_flight_analytics) all perform read/query operations on the EMS API.
Attacks that exploit this kind of access
find_event_types. It is categorised as a Read tool in the EMS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the EMS MCP Server MCP server in PolicyLayer and add a rule for find_event_types: 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 EMS MCP Server. Nothing to install.
find_event_types 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 find_event_types 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 find_event_types. 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.
find_event_types is provided by the EMS MCP Server MCP server (mattsq/ems-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
