create_project_collaborator

Add a collaborator to a project.

How to control create_project_collaborator ↓

AI agents use create_project_collaborator to create or update resources in QuantConnect — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your QuantConnect environment.

Medium Risk

This operation creates a new collaborator association within a project, which is a reversible modification of project state (the collaborator can be removed). It does not execute code, delete data, move funds, or trigger external operations.

From the tool's definition Tool name 'create_project_collaborator' and description 'Add a collaborator to a project' indicate a create/add operation that modifies project metadata by inserting a new collaborator record.

Documented attack patterns abuse exactly the kind of access create_project_collaborator 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 create_project_collaborator:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_project_collaborator": {
      "limits": [
        {
          "counter": "create_project_collaborator_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_project_collaborator stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register QuantConnect — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

What does the create_project_collaborator tool do? +

Add a collaborator to a project. It is categorised as a Write tool in the QuantConnect MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_project_collaborator? +

Register the QuantConnect MCP server in PolicyLayer and add a rule for create_project_collaborator: 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.

What risk level is create_project_collaborator? +

create_project_collaborator is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_project_collaborator? +

Yes. Add a rate_limit block to the create_project_collaborator 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.

How do I block create_project_collaborator completely? +

Set action: deny in the PolicyLayer policy for create_project_collaborator. 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.

What MCP server provides create_project_collaborator? +

create_project_collaborator 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.

Enforce policy on every QuantConnect tool call.
