List the Object Store files under a specific directory in
AI agents call list_object_store_files to retrieve information from QuantConnect without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a list of files from an object store directory. It performs a read-only query operation with no side effects, no data modification, and no capability to delete or execute operations. The blast radius of misuse is minimal—an agent could enumerate files but cannot alter, delete, or execute them.
From the tool's definition Tool name 'list_object_store_files' and description 'List the Object Store files under a specific directory' indicate querying/listing directory contents with no modification capability.
Documented attack patterns abuse exactly the kind of access list_object_store_files 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 list_object_store_files:
{
"version": "1",
"default": "deny",
"tools": {
"list_object_store_files": {}
}
}list_object_store_files is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List the Object Store files under a specific directory in. It is categorised as a Read tool in the QuantConnect MCP Server, which means it retrieves data without modifying state.
Register the QuantConnect MCP server in PolicyLayer and add a rule for list_object_store_files: 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.
list_object_store_files is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_object_store_files 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 list_object_store_files. 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.
list_object_store_files 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.
