AI agents call read_project_collaborators 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 queries and returns existing project collaborator information without modifying, deleting, or executing any operations. It is a straightforward read operation that retrieves metadata about a project's access list. The severity is low because unauthorized disclosure of collaborator information, while a privacy concern, does not enable direct financial harm, data destruction, or code execution.
From the tool's definition Tool name 'read_project_collaborators' and description 'List all collaborators on a project' clearly indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access read_project_collaborators 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_project_collaborators:
{
"version": "1",
"default": "deny",
"tools": {
"read_project_collaborators": {}
}
}read_project_collaborators is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List all collaborators on a project. 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_project_collaborators: 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_project_collaborators 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_project_collaborators 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_project_collaborators. 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_project_collaborators 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.
