WHAT IT DOES

What referrals does on Open Stocks MCP

AI agents call referrals to retrieve information from Open Stocks MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why referrals is rated Low

This tool retrieves referral program information, which is a read-only operation. It does not create, modify, delete, execute commands, or move money. The blast radius is minimal—an AI agent misusing this tool could only retrieve information about referral programs, not cause financial harm or data corruption. Even in the context of a financial trading server, this specific tool is purely informational.

From the tool's definition Tool name 'referrals' and description 'Gets referral program information' indicate a query operation that retrieves data without modification or side effects.

RECOMMENDED RULE

The rule that runs referrals safely

referrals Allowed

referrals is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "referrals": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Open Stocks MCP, apply this rule, and every referrals call is checked against it from then on.
