What bazel_visionos_test does on XcodeBazelMCP
AI agents invoke bazel_visionos_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.
Why bazel_visionos_test is rated High
The tool executes test code by running a Bazel build and test target on a visionOS simulator or device. 'Run' indicates active execution of code. While tests are generally benign, executing arbitrary test targets can trigger side effects, consume significant resources, or run malicious code embedded in test targets. This falls under Execute as it actively runs code/commands.

Attacks that exploit this kind of access
The rule that runs bazel_visionos_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_visionos_test, this is the rule to start with:
bazel_visionos_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.
The button opens the PolicyLayer dashboard: create your workspace, connect XcodeBazelMCP, apply this rule, and every bazel_visionos_test call is checked against it from then on.
Questions about bazel_visionos_test
Run a Bazel visionOS unit test target (visionos_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.
Register the XcodeBazel MCP server in PolicyLayer and add a rule for bazel_visionos_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.
bazel_visionos_test 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_visionos_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.
Set action: deny in the PolicyLayer policy for bazel_visionos_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.
bazel_visionos_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.
