AI agents use create_project_collaborator to create or update resources in QuantConnect MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your QuantConnect MCP Server environment.
This tool creates a new relationship (adds a collaborator) and modifies project permissions reversibly. While it could have security implications due to granting access to financial trading systems, the action itself is not destructive, financial, or code execution—it is account/permission management. It falls under Write category.
From the tool's definition Tool description states 'Add a collaborator to a project' with parameters to grant 'write permission' and 'live control permission'. This creates a new collaborator relationship and modifies project access controls.
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 MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_project_collaborator:
{
"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.

Add a collaborator to a project. Args: project_id: ID of the project to add collaborator to collaborator_user_id: User ID of the user to add as collaborator (from profile URL) collaboration_write: Grant write permission (default: True) collaboration_live_control: Grant live control permission (default: False) Returns: Dictionary containing collaborator addition result. It is categorised as a Write tool in the QuantConnect MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the QuantConnect MCP Server 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 MCP Server. Nothing to install.
create_project_collaborator is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
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.
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.
create_project_collaborator is provided by the QuantConnect MCP Server MCP server (taylorwilsdon/quantconnect-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
