Stream system logs on macOS, optionally filtered by process.
AI agents call bazel_macos_log to retrieve information from XcodeBazelMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and streams existing system logs without creating, modifying, deleting, or executing any operations. Filtering by process is a read-only query operation. While logs may contain sensitive information, the tool itself performs no side effects—it simply accesses already-generated diagnostic data.
From the tool's definition Tool name 'bazel_macos_log' and description 'Stream system logs on macOS, optionally filtered by process' indicates reading/querying existing log data with no modification or deletion capability.
Documented attack patterns abuse exactly the kind of access bazel_macos_log gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and XcodeBazelMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for bazel_macos_log:
{
"version": "1",
"default": "deny",
"tools": {
"bazel_macos_log": {}
}
}bazel_macos_log is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Stream system logs on macOS, optionally filtered by process. 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_log: 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_log 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_log 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_log. 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_log 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.
Start from XcodeBazelMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
