AI agents may call mod-tidy to permanently remove or destroy resources in Go. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.

Without a policy, an AI agent could call mod-tidy in a loop, permanently destroying resources in Go. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.

Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

These attack patterns abuse exactly the kind of access mod-tidy gives an agent. Each links to the full case and the policy that stops it:

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so mod-tidy only ever does what you allow.

What does the mod-tidy tool do? +

Runs go mod tidy to add missing and remove unused module dependencies.. It is categorised as a Destructive tool in the Go 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 mod-tidy? +

Register the Go MCP server in PolicyLayer and add a rule for mod-tidy: 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 Go. Nothing to install.

What risk level is mod-tidy? +

mod-tidy 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 mod-tidy? +

Yes. Add a rate_limit block to the mod-tidy 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 mod-tidy completely? +

Set action: deny in the PolicyLayer policy for mod-tidy. 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 mod-tidy? +

mod-tidy is provided by the Go MCP server (@paretools/go). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Go tool call.
