AI agents call delete_project to permanently remove resources in QuantConnect — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of a project in QuantConnect is an irreversible action that destroys data and cannot be undone. This falls squarely into the Destructive category as it removes resources permanently. Severity is high because accidental or malicious deletion of a trading project could result in loss of significant work, configurations, and algorithm code.
From the tool's definition Tool name is 'delete_project' with description 'Delete a project.' The verb 'delete' explicitly indicates irreversible removal of data.
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 QuantConnect, 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 QuantConnect MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the QuantConnect 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 QuantConnect. 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 QuantConnect MCP server (quantconnect/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
