Boot an iOS simulator
Starts simulator processes
Part of the Appium MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents invoke boot_simulator to trigger processes or run actions in Appium. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
boot_simulator can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

boot_simulator is one of the high-risk operations in Appium. For the full severity-focused view — only the high-risk tools with their recommended policies — see the breakdown for this server, or browse all high-risk tools across every MCP server.
Boot an iOS simulator. It is categorised as a Execute tool in the Appium MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Add a rule in your Intercept YAML policy under the tools section for boot_simulator. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Appium MCP server.
boot_simulator is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the boot_simulator rule in your Intercept 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 Intercept policy for boot_simulator. 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.
boot_simulator is provided by the Appium MCP server (@appium-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
