# browser_navigate A execute tool on the Looking Glass MCP server. Agent View of the PolicyLayer registry record for `browser_navigate`. HTML page: https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-navigate ## Facts - Tool: `browser_navigate` - Server: Looking Glass (`looking-glass-mcp`) — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp.md - Install: `npx -y looking-glass-mcp` - Homepage: https://github.com/Sahib-Sawhney-WH/LookingGlass - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 1 (1 required) - Recommended policy verdict: Rate-limited ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `url` | string | yes | URL to navigate to | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "browser_navigate", "arguments": { "url": "" } } } ``` ## Why browser_navigate is rated High Navigation is an external operation with effects that depend on the URL argument—it can load arbitrary web content, trigger requests, and cause side effects on remote systems. While not directly destructive or financial, it clearly executes an action rather than reading data. Confidence is high based on the function name and server context, though lowered slightly due to the empty description. From the tool's own definition: "Tool name 'browser_navigate' combined with server description 'AI-native browser for agents' indicates this tool triggers browser navigation actions." Risk signals: Accepts URL/endpoint input (url) ## Use case AI agents invoke browser_navigate to trigger actions in Looking Glass. 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**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Looking Glass: ```json { "version": "1", "default": "deny", "tools": { "browser_navigate": { "limits": [ { "counter": "browser_navigate_rate", "window": "minute", "max": 10, "scope": "grant" } ] } } } ``` ## Other tools on Looking Glass (70) - `browser_clean_slate` — Destructive — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-clean-slate.md - `browser_clear_history` — Destructive — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-clear-history.md - `browser_clear_mocks` — Destructive — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-clear-mocks.md - `browser_clear_storage` — Destructive — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-clear-storage.md - `browser_close` — Destructive — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-close.md - `session_end` — Destructive — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/session-end.md - `test_chaos_clear` — Destructive — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/test-chaos-clear.md - `vault_delete` — Destructive — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/vault-delete.md - `browser_click` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-click.md - `browser_drag` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-drag.md - `browser_evaluate` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-evaluate.md - `browser_explore` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-explore.md - `browser_fill_and_submit` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-fill-and-submit.md - `browser_go` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-go.md - `browser_go_back` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-go-back.md - `browser_go_forward` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-go-forward.md - `browser_hover` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-hover.md - `browser_login` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-login.md - `browser_mock_route` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-mock-route.md - `browser_performance_audit` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-performance-audit.md - `browser_press_key` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-press-key.md - `browser_recover` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-recover.md - `browser_resolve_element` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-resolve-element.md - `browser_scroll` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-scroll.md - `browser_select_option` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-select-option.md - `browser_smart_click` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-smart-click.md - `browser_tab_new` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-tab-new.md - `browser_tab_select` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-tab-select.md - `browser_type` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-type.md - `browser_wait_for` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-wait-for.md - …and 40 more: https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp.md ## For agents This record is a snapshot.
