simulator_wait_for_element

Wait for an accessibility element to appear on screen. Polls until the element matching your criteria (label, role, or text) appears, or times out. Like Playwright's browser_wait_for.

Part of the Preflight Ios MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

// WHEN AI AGENTS USE THIS TOOL

AI agents invoke simulator_wait_for_element to trigger processes or run actions in Preflight Ios. 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.

// WHY ENFORCE A POLICY ON SIMULATOR_WAIT_FOR_ELEMENT

simulator_wait_for_element 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.

// RECOMMENDED POLICY

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

What does the simulator_wait_for_element tool do? +

Wait for an accessibility element to appear on screen. Polls until the element matching your criteria (label, role, or text) appears, or times out. Like Playwright's browser_wait_for.. It is categorised as a Execute tool in the Preflight Ios MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on simulator_wait_for_element? +

Add a rule in your Intercept YAML policy under the tools section for simulator_wait_for_element. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Preflight Ios MCP server.

What risk level is simulator_wait_for_element? +

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

Can I rate-limit simulator_wait_for_element? +

Yes. Add a rate_limit block to the simulator_wait_for_element 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.

How do I block simulator_wait_for_element completely? +

Set action: deny in the Intercept policy for simulator_wait_for_element. 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 simulator_wait_for_element? +

simulator_wait_for_element is provided by the Preflight Ios MCP server (preflight-ios-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
