Returns the latest version of the QC MCP Server released.
AI agents call read_latest_mcp_server_version 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 only queries and returns version information about the MCP server itself. It performs no data modification, code execution, deletion, or financial operations. The information returned is metadata about the server state, making it a straightforward Read operation with minimal security risk even if misused by an agent.
From the tool's definition Tool name 'read_latest_mcp_server_version' explicitly contains 'read' and description states it 'Returns the latest version' — a pure retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access read_latest_mcp_server_version 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 read_latest_mcp_server_version:
{
"version": "1",
"default": "deny",
"tools": {
"read_latest_mcp_server_version": {}
}
}read_latest_mcp_server_version is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
