Why create_order needs a policy

The server description explicitly mentions 'order placement' as a capability. Misuse could result in unintended financial transactions, making this Financial category with critical severity.

From the tool's definition Tool name 'create_order' on a server described as enabling 'order placement' for a 'Trading212 brokerage account'; sibling tools include financial portfolio and pie management tools.

POLICY

How to control create_order

PolicyLayer is an MCP gateway — it sits between your AI agents and Trading212 MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_order:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_order": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to create_order is blocked until a human approves it. The rest of the server keeps working.
