WHAT IT DOES

What bazel_watchos_run does on XcodeBazelMCP

AI agents invoke bazel_watchos_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.

RISK

Why bazel_watchos_run is rated High

This tool performs code execution by building and launching a watchOS app. While the description is truncated, the key verbs 'build' and 'launch' indicate it runs external operations whose effects depend on arguments (target selection, build flags, etc.). This falls under Execute rather than Write because it invokes build systems and app launch mechanisms with unpredictable real-world consequences.

From the tool's definition "Build and launch a Bazel watchOS application" — the tool executes a build process and launches an application, which are operations that trigger external side effects on the watchOS platform.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs bazel_watchos_run 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_watchos_run, this is the rule to start with:

bazel_watchos_run Rate-limited

bazel_watchos_run 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_watchos_run call is checked against it from then on.

FAQ

Questions about bazel_watchos_run

What does the bazel_watchos_run tool do? +

Build and launch a Bazel watchOS application via. 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_watchos_run? +

Register the XcodeBazel MCP server in PolicyLayer and add a rule for bazel_watchos_run: 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_watchos_run? +

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

Can I rate-limit bazel_watchos_run? +

Yes. Add a rate_limit block to the bazel_watchos_run 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_watchos_run completely? +

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

bazel_watchos_run 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.
