WHAT IT DOES

What runtime_restart_application does on Anypoint MCP Server

AI agents invoke runtime_restart_application to trigger actions in Anypoint MCP Server. 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 runtime_restart_application needs a policy

This tool performs a restart operation on a deployed application in MuleSoft's Runtime Manager. While not destructive (data is not deleted or lost), it executes a significant operational action that stops and starts an application instance. The blast radius is high because unintended restarts could cause service interruptions, downtime, and impact dependent systems.

From the tool's definition Tool name contains 'restart' and description explicitly states it will 'Restart a Runtime Manager application (stop then start)', which triggers external operations (stopping and starting application instances) whose effects depend on the deployment ID…

Verdict

runtime_restart_application Rate-limited

runtime_restart_application stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about runtime_restart_application

What does the runtime_restart_application tool do? +

Restart a Runtime Manager application (stop then start). Call runtime_list_deployments first to obtain the deploymentId. It is categorised as a Execute tool in the Anypoint MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on runtime_restart_application? +

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

What risk level is runtime_restart_application? +

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

Can I rate-limit runtime_restart_application? +

Yes. Add a rate_limit block to the runtime_restart_application 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 runtime_restart_application completely? +

Set action: deny in the PolicyLayer policy for runtime_restart_application. 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 runtime_restart_application? +

runtime_restart_application is provided by the Anypoint MCP Server MCP server (sravannerella/mulesoft-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
