Get the currently active ServiceNow instance name and URL
AI agents call get_current_instance 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 tool performs a read-only operation that retrieves configuration metadata (instance name and URL) from ServiceNow. No data is created, modified, deleted, or executed. The information returned is fundamental infrastructure metadata needed for context. The blast radius of misuse is minimal—an AI agent could only learn which ServiceNow instance is active, which does not compromise data confidentiality or integrity.
From the tool's definition Tool name and description indicate a query operation: 'Get the currently active ServiceNow instance name and URL'. This retrieves metadata about the active instance with no side effects.
Attacks that exploit this kind of access
Get the currently active ServiceNow instance name and URL. 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_current_instance: 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_current_instance 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_current_instance 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_current_instance. 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_current_instance 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.
