List all configurable agent workspaces
AI agents call list_workspaces 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 simple query/list operation to retrieve workspace metadata with no modification, deletion, or execution of code. The information exposed (workspace names and configurations) is typically accessible to authorized ServiceNow users for administrative purposes. The blast radius is minimal—an AI agent misusing this to enumerate workspaces causes no direct harm beyond potential reconnaissance.
From the tool's definition Tool name 'list_workspaces' and description 'List all configurable agent workspaces' indicate a retrieval operation that enumerates existing workspace configurations.
Attacks that exploit this kind of access
List all configurable agent workspaces. 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 list_workspaces: 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.
list_workspaces 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 list_workspaces 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 list_workspaces. 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.
list_workspaces 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.
