Why browser_navigate_forward needs a policy

Browser navigation commands execute state-changing operations in an external system (web browser). While not immediately destructive, uncontrolled navigation could access sensitive resources, trigger unwanted transactions, or cause side effects in web applications.

From the tool's definition Tool named 'browser_navigate_forward' with empty description; inferred to trigger browser navigation actions, which are external operations whose effects depend on context.

POLICY

How to control browser_navigate_forward

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

policy.json

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

browser_navigate_forward 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 Awslabs Valkey — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
