Why ibkr_oca_group needs a policy

OCA (One Cancels All) groups in IBKR are order grouping mechanisms. This tool could be reading, writing, or managing OCA groups, but the empty description provides no clarity. Given the ambiguity, I cannot confidently assign a more specific category. If it creates or modifies OCA order groups, it would be Write or even Financial. Confidence is very low due to the empty description.

From the tool's definition Tool name 'ibkr_oca_group' and empty description provide no information about what the tool does.

POLICY

How to control ibkr_oca_group

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ibkr_oca_group": {
      "limits": [
        {
          "counter": "ibkr_oca_group_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

ibkr_oca_group gets a rate cap, and everything else on the server is denied unless you say otherwise.

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