Delete a file from a QuantConnect project. Args: project_id: ID of the project containing the file to delete name: Name of the file to delete Returns: Dictionary containing deletion result
AI agents call delete_file to permanently remove resources in QuantConnect MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes data (project files) without possibility of undo. While the blast radius is limited to project files rather than the entire system, deletion of trading strategy code or research data in a quantitative trading platform could result in loss of valuable intellectual property, research work, or active trading logic. This fits the Destructive category as the primary risk.
From the tool's definition Tool name is 'delete_file' and description explicitly states 'Delete a file from a QuantConnect project.' The action is irreversible—once deleted, the file cannot be recovered without external backups.
Documented attack patterns abuse exactly the kind of access delete_file gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and QuantConnect MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_file:
{
"version": "1",
"default": "deny",
"hide": [
"delete_file"
]
}delete_file 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 a QuantConnect project. Args: project_id: ID of the project containing the file to delete name: Name of the file to delete Returns: Dictionary containing deletion result. It is categorised as a Destructive tool in the QuantConnect MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the QuantConnect MCP Server 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 QuantConnect MCP Server. 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 QuantConnect MCP Server MCP server (taylorwilsdon/quantconnect-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
