Delete a file.
AI agents call delete_file to permanently remove resources in Project Creator MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The delete_file tool performs an irreversible deletion of file system data. Even though the blast radius is confined to files within the project context (rather than system-wide), deletion cannot be undone without external recovery mechanisms.
From the tool's definition Tool name is 'delete_file' with description 'Delete a file.' This operation irreversibly removes data from the file system.
Attacks that exploit this kind of access
Delete a file. It is categorised as a Destructive tool in the Project Creator MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Project Creator MCP server in PolicyLayer and add a rule for delete_file: 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 Project Creator MCP. Nothing to install.
delete_file 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_file 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_file. 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_file is provided by the Project Creator MCP server (jackalterman/project-creator-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
