Why browser_navigate_forward needs a policy

Browser navigation commands are Execute-category actions that trigger external operations (browser state changes). Without a description, confidence is reduced. Medium severity reflects that browser navigation alone has limited blast radius compared to data access or deletion, but could be misused in browser-based exploitation chains or to navigate to malicious sites if arguments are user-controlled.

From the tool's definition Tool named 'browser_navigate_forward' with empty description. The name indicates browser automation/navigation control.

POLICY

How to control browser_navigate_forward

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS API MCP Server, 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 AWS API MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about browser_navigate_forward

What does the browser_navigate_forward tool do? +

What risk level is browser_navigate_forward? +

browser_navigate_forward is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit browser_navigate_forward? +

Yes. Add a rate_limit block to the browser_navigate_forward rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block browser_navigate_forward completely? +

Set action: deny in the PolicyLayer policy for browser_navigate_forward. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides browser_navigate_forward? +

browser_navigate_forward is provided by the AWS API MCP Server MCP server (awslabs.aws-api-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every AWS API MCP Server tool call.

Start from AWS API MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
