WHAT IT DOES

What bazel_macos_test does on XcodeBazelMCP

AI agents invoke bazel_macos_test 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_macos_test is rated High

This tool executes test code on the macOS platform via Bazel. Running tests executes arbitrary code (the test targets and their dependencies), which can have side effects depending on what the tests do. The blast radius is high because arbitrary code execution could affect the local system, file system, or external services.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs bazel_macos_test 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_macos_test, this is the rule to start with:

bazel_macos_test Rate-limited

bazel_macos_test 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.

  "version": "1",

          "counter": "bazel_macos_test_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect XcodeBazelMCP, apply this rule, and every bazel_macos_test call is checked against it from then on.

FAQ

Questions about bazel_macos_test

What does the bazel_macos_test tool do? +

Run a Bazel macOS unit test target (macos_unit_test). 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_macos_test? +

Register the XcodeBazel MCP server in PolicyLayer and add a rule for bazel_macos_test: 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_macos_test? +

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

Can I rate-limit bazel_macos_test? +

Yes. Add a rate_limit block to the bazel_macos_test 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_macos_test completely? +

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

bazel_macos_test 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.
