# browser_get_cookies A read tool on the Looking Glass MCP server. Agent View of the PolicyLayer registry record for `browser_get_cookies`. HTML page: https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-get-cookies ## Facts - Tool: `browser_get_cookies` - 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: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 1 - Recommended policy verdict: Allowed ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `url` | string | no | Filter cookies by URL | 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_get_cookies", "arguments": {} } } ``` ## Why browser_get_cookies is rated Low Cookie retrieval is a read-only operation that queries stored browser state without modification or deletion. While cookies can contain sensitive data (session tokens, auth credentials), the tool itself performs no destructive or state-altering action. From the tool's own definition: "Tool name 'browser_get_cookies' indicates retrieval of cookie data; 'get' is a read operation pattern. The tool description is empty, but the name and context (AI-native browser) strongly suggest data retrieval with no side effects." Risk signals: Accepts URL/endpoint input (url) ## Use case AI agents call browser_get_cookies to retrieve information from Looking Glass without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Looking Glass: ```json { "version": "1", "default": "deny", "tools": { "browser_get_cookies": {} } } ``` ## 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_navigate` — Execute — https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp/browser-navigate.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 - …and 40 more: https://policylayer.com/tools/io-github-sahib-sawhney-wh-looking-glass-mcp.md ## For agents This record is a snapshot.
