AI agents call file_delete to permanently remove resources in Codehooks Io MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes files from the server, a destructive operation that cannot be undone. While severity is not 'critical' because it is scoped to individual files rather than entire systems or databases, the permanent data loss capability and lack of reversibility warrant 'high' severity.
From the tool's definition Tool name is 'file_delete' with description 'Delete a file from server' — uses the verb 'Delete' which indicates irreversible removal of data.
Documented attack patterns abuse exactly the kind of access file_delete gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Codehooks Io MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for file_delete:
{
"version": "1",
"default": "deny",
"hide": [
"file_delete"
]
}file_delete 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 file from server. It is categorised as a Destructive tool in the Codehooks Io MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Codehooks Io MCP Server MCP server in PolicyLayer and add a rule for file_delete: 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 Codehooks Io MCP Server. Nothing to install.
file_delete 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 file_delete 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 file_delete. 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.
file_delete is provided by the Codehooks Io MCP Server MCP server (restdb/codehooks-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Codehooks Io MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
