Restarts the Tauri application and waits for it to come back online. Use when the app is in a broken state, unresponsive, or needs a fresh start. If the app is completely frozen, it will be force-killed. This is a destructive operation — all in-memory state will be lost.
AI agents call restart_app to permanently remove resources in Tauri Plugin — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool forcibly kills and restarts the application, irreversibly destroying all in-memory state. While the app is restarted (so the application itself isn't permanently deleted), the operation is explicitly labeled destructive and causes irreversible loss of runtime state, session data, and any unsaved work.
From the tool's definition 'This is a destructive operation — all in-memory state will be lost' and 'If the app is completely frozen, it will be force-killed'
Documented attack patterns abuse exactly the kind of access restart_app gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Tauri Plugin, and nothing reaches the server without passing your rules. This is the rule we recommend for restart_app:
{
"version": "1",
"default": "deny",
"hide": [
"restart_app"
]
}restart_app disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Restarts the Tauri application and waits for it to come back online. Use when the app is in a broken state, unresponsive, or needs a fresh start. If the app is completely frozen, it will be force-killed. This is a destructive operation — all in-memory state will be lost. It is categorised as a Destructive tool in the Tauri Plugin MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Tauri Plugin MCP server in PolicyLayer and add a rule for restart_app: 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 Tauri Plugin. Nothing to install.
restart_app is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the restart_app 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 restart_app. 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.
restart_app is provided by the Tauri Plugin MCP server (p3gleg/tauri-plugin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
