# navigate_page Navigates the currently selected page to a URL. Agent View of the PolicyLayer registry record for `navigate_page`. HTML page: https://policylayer.com/tools/1600822305-js-reverse-mcp/navigate-page ## Facts - Tool: `navigate_page` - Server: Js Reverse (`1600822305/js-reverse-mcp`) — https://policylayer.com/tools/1600822305-js-reverse-mcp.md - Homepage: https://github.com/1600822305/js-reverse-mcp - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "navigate_page", "arguments": {} } } ``` ## Why navigate_page is rated High Navigation is an Execute action because it triggers external effects (page load, script execution, network requests, state changes) whose consequences depend on the URL argument. While not immediately destructive or financial, it ranks above Write because browser navigation can execute code and cause side effects beyond simple data modification. From the tool's own definition: "Tool performs 'navigates the currently selected page to a URL' — a browser control action that executes in an external environment (Chrome). The MCP server description confirms it 'enables AI coding assistants to control browsers'." ## Use case AI agents invoke navigate_page to trigger actions in Js Reverse. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
