Why toggle_sidebar needs a policy

This tool triggers a UI state change (showing/hiding a sidebar), which is an external operation affecting the interface. It's not a pure read, nor does it write/destroy data. It falls under Execute as it triggers an interface action. Blast radius is low since it only affects visual presentation with no data implications.

POLICY

How to control toggle_sidebar

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "toggle_sidebar": {
      "limits": [
        {
          "counter": "toggle_sidebar_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

toggle_sidebar stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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