AI agents call delete_project to permanently remove resources in Clockify MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of a project cannot be undone and has a broad blast radius in a time-tracking system: it removes historical records, breaks reporting, and affects all team members assigned to that project. This meets the Destructive category threshold.
From the tool's definition Tool name 'delete_project' explicitly indicates deletion. Description states 'Delete a project' — a destructive action that irreversibly removes a project and likely all associated data (time entries, tasks, assignments).
Documented attack patterns abuse exactly the kind of access delete_project gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Clockify MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_project:
{
"version": "1",
"default": "deny",
"hide": [
"delete_project"
]
}delete_project disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a project. It is categorised as a Destructive tool in the Clockify MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Clockify MCP Server MCP server in PolicyLayer and add a rule for delete_project: 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 Clockify MCP Server. Nothing to install.
delete_project is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_project 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 delete_project. 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.
delete_project is provided by the Clockify MCP Server MCP server (ratheesh-aot/clockify-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Clockify MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
