Override the simulator status bar (time, battery, network, etc.). Useful for consistent screenshots.
AI agents invoke bazel_ios_set_status_bar to trigger actions in XcodeBazelMCP. 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.
This tool modifies the simulator's display state by overriding status bar properties. It triggers an external operation on the simulator environment. While not destructive or financially impactful, it executes a change on a running simulator instance. The blast radius is low as it only affects the visual appearance of the simulator status bar, primarily used for screenshot consistency.

Documented attack patterns abuse exactly the kind of access bazel_ios_set_status_bar gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and XcodeBazelMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for bazel_ios_set_status_bar:
{
"version": "1",
"default": "deny",
"tools": {
"bazel_ios_set_status_bar": {
"limits": [
{
"counter": "bazel_ios_set_status_bar_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}bazel_ios_set_status_bar 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.

Override the simulator status bar (time, battery, network, etc.). Useful for consistent screenshots. It is categorised as a Execute tool in the XcodeBazelMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the XcodeBazel MCP server in PolicyLayer and add a rule for bazel_ios_set_status_bar: 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 XcodeBazelMCP. Nothing to install.
bazel_ios_set_status_bar 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 bazel_ios_set_status_bar 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 bazel_ios_set_status_bar. 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.
bazel_ios_set_status_bar is provided by the XcodeBazel MCP server (xcodebazelmcp/xcodebazelmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from XcodeBazelMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
