navigate

THE RISK

High Risk

Navigation control is an active operation that triggers external effects (loading new pages, executing page code, side effects from remote content) whose consequences depend on the target URL argument. This goes beyond passive Read (which would be querying the current URL) and is not destructive or financial, but qualifies as Execute because it runs/triggers operations within the Tauri application context.

From the tool's definition Tool 'navigate' that 'Controls webview navigation' allows triggering navigation actions in a Tauri application's webview, which can redirect to arbitrary URLs or load content, affecting the running application's state and behavior.

Documented attack patterns abuse exactly the kind of access navigate gives an agent:

HOW TO CONTROL NAVIGATE

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

policy.json

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

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

FAQ

What does the navigate tool do? +

Controls webview navigation. It is categorised as a Execute tool in the Tauri Plugin MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on navigate? +

Register the Tauri Plugin MCP server in PolicyLayer and add a rule for navigate: 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 Tauri Plugin. Nothing to install.

What risk level is navigate? +

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

Can I rate-limit navigate? +

Yes. Add a rate_limit block to the navigate 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 navigate completely? +

Set action: deny in the PolicyLayer policy for navigate. 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 navigate? +

navigate is provided by the Tauri Plugin MCP server (p3gleg/tauri-plugin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Tauri Plugin tool call.
