snow_redeploy_script_endpoint · Serac MCP: Risk & Policy

WHAT IT DOES

What snow_redeploy_script_endpoint does on Serac

AI agents invoke snow_redeploy_script_endpoint to trigger actions in Serac. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why snow_redeploy_script_endpoint needs a policy

This tool redeplooys a REST endpoint designed for executing scripts (/api/snow_flow_exec/execute), making it an Execute-category action. The ability to force-redeploy a code execution infrastructure component in ServiceNow poses critical risk: an AI agent could redeploy a compromised or malicious executor, bypass security controls, or cause widespread service disruption across the enterprise platform.

From the tool's definition "Force-redeploy the Serac scripted REST executor endpoint (/api/snow_flow_exec/execute). Use when snow_execute_script / UI policy tools fail with" — explicitly redeploys a script execution endpoint that permits arbitrary code execution.

What risk level is snow_redeploy_script_endpoint? +

snow_redeploy_script_endpoint is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit snow_redeploy_script_endpoint? +

Yes. Add a rate_limit block to the snow_redeploy_script_endpoint 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.

How do I block snow_redeploy_script_endpoint completely? +

Set action: deny in the PolicyLayer policy for snow_redeploy_script_endpoint. 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.

What MCP server provides snow_redeploy_script_endpoint? +

snow_redeploy_script_endpoint is provided by the Serac MCP server (serac-labs/serac). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
