WHAT IT DOES

What bazel_ios_device_log_start does on XcodeBazelMCP

AI agents invoke bazel_ios_device_log_start 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.

RISK

Why bazel_ios_device_log_start is rated High

This tool executes a command to begin a continuous logging/monitoring process on a connected device. While not destructive and not creating lasting data modifications, it triggers an external operation whose behavior depends on the target device state and arguments provided. The tool interacts with device system services, making it an Execute category tool.

From the tool's definition Starts log capturing from a physical iOS device using pymobiledevice3 or idevicesyslog - actively initiates a system operation with external effects

RECOMMENDED RULE

The rule that runs bazel_ios_device_log_start 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_log_start, this is the rule to start with:

bazel_ios_device_log_start Rate-limited

bazel_ios_device_log_start 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.

FAQ

Questions about bazel_ios_device_log_start

What does the bazel_ios_device_log_start tool do? +

Start capturing logs from a connected physical iOS device. Tries pymobiledevice3 first (iOS 17+ via CoreDevice tunnel), falls back to idevicesyslog for older devices. 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.

How do I enforce a policy on bazel_ios_device_log_start? +

Register the XcodeBazel MCP server in PolicyLayer and add a rule for bazel_ios_device_log_start: 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.

What risk level is bazel_ios_device_log_start? +

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

Can I rate-limit bazel_ios_device_log_start? +

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

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

bazel_ios_device_log_start 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.
