THE RISK

Why swift_package_clean needs a policy

Cleaning build artifacts irreversibly deletes compiled outputs and cached build data. While source code is preserved, the build artifacts are permanently removed and cannot be recovered without rebuilding. This is a destructive operation on the build cache/artifacts directory.

POLICY

How to control swift_package_clean

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 swift_package_clean:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "swift_package_clean"
  ]
}

swift_package_clean disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register XcodeBazelMCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about swift_package_clean

What does the swift_package_clean tool do? +

Clean build artifacts of a Swift package (. It is categorised as a Destructive tool in the XcodeBazelMCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on swift_package_clean? +

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

swift_package_clean is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit swift_package_clean? +

Yes. Add a rate_limit block to the swift_package_clean 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 swift_package_clean completely? +

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

swift_package_clean 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.

Enforce policy on every XcodeBazelMCP tool call.

Start from XcodeBazelMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
