Get full details and script of a UI Action (requires SCRIPTING_ENABLED=true)
AI agents call get_ui_action 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 fundamentally a Read operation—it retrieves details and scripts associated with a UI Action in ServiceNow. However, it escalates from 'low' to 'medium' severity because (1) scripts may contain sensitive logic, embedded credentials, or code exploitable by a malicious actor, and (2) the requirement flag SCRIPTING_ENABLED suggests the tool accesses privileged scripting content.
From the tool's definition Tool name 'get_ui_action' and description 'Get full details and script of a UI Action' indicate data retrieval.

Get full details and script of a UI Action (requires SCRIPTING_ENABLED=true). 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_ui_action: 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_ui_action 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_ui_action 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_ui_action. 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_ui_action 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.
