Get details of a specific registered event definition
AI agents call get_event_registry_entry to retrieve information from ServiceNow-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward data retrieval operation. It queries and returns information about an event definition from ServiceNow's event registry without creating, modifying, deleting, or executing anything. The blast radius of misuse is minimal—an AI agent could retrieve unnecessary event metadata but cannot cause harm with this read-only operation.
From the tool's definition Tool name includes 'get', and description states 'Get details of a specific registered event definition' — retrieving metadata about an event registry entry with no modification or execution capability.
Attacks that exploit this kind of access
Get details of a specific registered event definition. It is categorised as a Read tool in the ServiceNow-MCP MCP Server, which means it retrieves data without modifying state.
Register the ServiceNow- MCP server in PolicyLayer and add a rule for get_event_registry_entry: 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 ServiceNow-MCP. Nothing to install.
get_event_registry_entry 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 get_event_registry_entry 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 get_event_registry_entry. 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.
get_event_registry_entry is provided by the ServiceNow- MCP server (tedorigawa001/servicenow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
