What bazel_macos_discover_targets does on XcodeBazelMCP
AI agents call bazel_macos_discover_targets to retrieve information from XcodeBazelMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why bazel_macos_discover_targets is rated Low
This tool retrieves and lists Bazel targets for macOS applications and unit tests. It performs a query operation that returns information about the build system without creating, modifying, executing, or deleting anything. The blast radius of misuse is minimal—an agent could discover private target information but cannot affect build artifacts, execute code, or modify the project structure.
From the tool's definition Tool uses 'bazel query' to discover targets; described as discovering/listing targets with no modification or execution capability. The verb 'discover' and use of 'query' indicate read-only information retrieval.
Attacks that exploit this kind of access
The rule that runs bazel_macos_discover_targets 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_discover_targets, this is the rule to start with:
bazel_macos_discover_targets is read-only, so it stays allowed. 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_macos_discover_targets call is checked against it from then on.
Questions about bazel_macos_discover_targets
Discover Bazel macOS application and unit test targets using bazel query. It is categorised as a Read tool in the XcodeBazelMCP MCP Server, which means it retrieves data without modifying state.
Register the XcodeBazel MCP server in PolicyLayer and add a rule for bazel_macos_discover_targets: 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_macos_discover_targets is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the bazel_macos_discover_targets 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_macos_discover_targets. 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_macos_discover_targets 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.
