What bazel_daemon_stop does on XcodeBazelMCP
AI agents invoke bazel_daemon_stop 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_daemon_stop is rated High
This tool executes a command to stop a background daemon process and clear associated metadata. While not destructive to user data (the daemon can be restarted), it triggers an external operation whose effects are immediate and irreversible until the daemon is restarted. This fits the Execute category: it runs a command that triggers external operations whose effects depend on context.
From the tool's definition Tool description states 'Stop the per-workspace background daemon and clear its tracked operation metadata.' The action of stopping a daemon and clearing its state represents executing a control operation that halts running processes and modifies system state.
Attacks that exploit this kind of access
The rule that runs bazel_daemon_stop 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_daemon_stop, this is the rule to start with:
bazel_daemon_stop 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_daemon_stop call is checked against it from then on.
Questions about bazel_daemon_stop
Stop the per-workspace background daemon and clear its tracked operation metadata. 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_daemon_stop: 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_daemon_stop 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_daemon_stop 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_daemon_stop. 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_daemon_stop 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.
