Get a single incident by sys_id or number
AI agents call incidents_get to retrieve information from ServiceNow MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves incident data from ServiceNow by identifier. It performs a query/fetch operation with no side effects—no data is created, modified, deleted, or executed. The blast radius of misuse is minimal; an attacker could only read incident information to which they already have access through the ITSM system. This is a classic Read operation.
From the tool's definition Tool name 'incidents_get' and description 'Get a single incident by sys_id or number' indicate a retrieval operation with no modification or destructive capability.

Register the ServiceNow MCP Server MCP server in PolicyLayer and add a rule for incidents_get: 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 Server. Nothing to install.
incidents_get 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 incidents_get 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 incidents_get. 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.
