What bazel_ios_device_pair does on XcodeBazelMCP
AI agents invoke bazel_ios_device_pair 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.
Why bazel_ios_device_pair is rated High
Pairing with a physical iOS device triggers an external operation that establishes a trust relationship between the host machine and the device. This is not a simple read, write, or destructive action — it executes a device pairing workflow with real-world side effects (device trust state changes). The blast radius is medium since misuse could pair unauthorized devices or disrupt existing pairing configurations.

Attacks that exploit this kind of access
The rule that runs bazel_ios_device_pair safely
PolicyLayer is an MCP gateway: it sits between your AI agents and XcodeBazelMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For bazel_ios_device_pair, this is the rule to start with:
bazel_ios_device_pair 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.
The button opens the PolicyLayer dashboard: create your workspace, connect XcodeBazelMCP, apply this rule, and every bazel_ios_device_pair call is checked against it from then on.
Questions about bazel_ios_device_pair
Pair with a physical iOS device for development. 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_device_pair: 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_device_pair 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_device_pair 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_device_pair. 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_device_pair 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.
