Returns the version of the QC MCP Server that's running.
AI agents call read_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 performs a read-only operation that retrieves metadata about the MCP server version. It does not create, modify, delete, or execute any operations—it merely queries and returns existing version information. This is a classic Read category action with minimal security risk.
From the tool's definition Tool name 'read_mcp_server_version' and description 'Returns the version of the QC MCP Server that's running' indicate a simple query operation that retrieves version information with no side effects.
Documented attack patterns abuse exactly the kind of access read_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_mcp_server_version:
{
"version": "1",
"default": "deny",
"tools": {
"read_mcp_server_version": {}
}
}read_mcp_server_version is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Returns the version of the QC MCP Server that's running. 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 read_mcp_server_version: 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.
read_mcp_server_version 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 read_mcp_server_version 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 read_mcp_server_version. 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.
read_mcp_server_version 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.
