long_press · Sl Test MCP: Risk & Policy

WHAT IT DOES

What long_press does on Sl Test

AI agents invoke long_press to trigger actions in Sl Test. 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 long_press needs a policy

This tool executes a UI gesture (long press) on a device or simulator, which can trigger arbitrary application actions depending on where and what is pressed. It is an external operation whose effects depend on the arguments (coordinates and duration). Misuse could trigger unintended app behaviors, but blast radius is generally constrained to the UI context of the app under test.

From the tool's definition Long press at specific coordinates for given duration (ms)" — triggers a physical gesture/UI interaction at specified coordinates on a simulated or real device

Verdict

long_press Rate-limited

long_press 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Sl Test, so you can run agents against it safely.

FAQ

Questions about long_press

What does the long_press tool do? +

Long press at specific coordinates for given duration (ms). Use describe_ui for precise coordinates (don. It is categorised as a Execute tool in the Sl Test MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on long_press? +

Register the Sl Test MCP server in PolicyLayer and add a rule for long_press: 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 Sl Test. Nothing to install.

What risk level is long_press? +

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

Can I rate-limit long_press? +

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

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

long_press is provided by the Sl Test MCP server (sampsonky/xcodebuildmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
