THE RISK

Why browser_navigate_forward needs a policy

Browser navigation is an Execute category action because it triggers external operations and side effects (page loads, script execution on target sites, potential state changes). Without a description, confidence is moderate. Severity is medium because misuse could navigate to malicious sites or trigger unintended page actions, but the blast radius is limited compared to code execution or data destruction.

From the tool's definition Tool named 'browser_navigate_forward' with empty description. The name suggests it triggers browser navigation actions, which are external operations whose effects depend on context (which page/site is navigated to).

POLICY

How to control browser_navigate_forward

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS IoT SiteWise 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 IoT SiteWise 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.

FAQ

Questions about browser_navigate_forward

What does the browser_navigate_forward tool do? +

browser_navigate_forward. It is categorised as a Execute tool in the AWS IoT SiteWise MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on browser_navigate_forward? +

Register the AWS IoT SiteWise MCP Server MCP server in PolicyLayer and add a rule for browser_navigate_forward: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AWS IoT SiteWise MCP Server. Nothing to install.

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 IoT SiteWise MCP Server MCP server (awslabs.aws-iot-sitewise-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 IoT SiteWise MCP Server tool call.

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