## Why bazel_ios_build_and_run is rated High

This tool executes a build process and deploys/launches an application on a device or simulator, which are external side effects. It runs code compilation and arbitrary app installation/execution, making it Execute rather than Write. The build process could produce arbitrary binaries or trigger unintended side effects depending on the Bazel configuration and target specified.

From the tool's own definition: "The tool name 'bazel_ios_build_and_run' and description explicitly state it 'Build[s] a Bazel iOS app, install[s] it on a simulator or physical device, and launch[s] it.' These are external operations (building, installing, launching) whose effects depend on…"

## Use case

AI agents invoke bazel_ios_build_and_run 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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches XcodeBazelMCP:
