remove_portfolio_position

THE RISK

Critical Risk

This tool irreversibly removes portfolio positions. When shares=None, it deletes the entire position with no indication of recovery mechanism. Modifying portfolio holdings (especially full removal) is destructive in nature since financial position data would be lost. The blast radius is high as an AI agent could inadvertently wipe out tracked portfolio positions entirely.

From the tool's definition Remove or reduce a portfolio position... shares: Number of shares to remove (None = remove entire position)

HOW TO CONTROL REMOVE_PORTFOLIO_POSITION

PolicyLayer is an MCP gateway — it sits between your AI agents and MaverickMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for remove_portfolio_position:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "remove_portfolio_position"
  ]
}

remove_portfolio_position disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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