HTML page: https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/get-response-body ## Facts - Tool: `get_response_body` - Server: Playwright MCP Server (`alexrwilliam/playwright-mcp-server`) — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server.md - Homepage: https://github.com/alexrwilliam/playwright-mcp-server - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "get_response_body", "arguments": {} } } ``` ## Why get_response_body is rated Low This tool retrieves response body content from web requests—a read operation with no side effects on the target system or the browser state. While it could theoretically exfiltrate sensitive data if the target page contains such content, the tool itself performs only data retrieval. Severity is low because misuse would be limited to information disclosure rather than modification, deletion, or code execution. From the tool's own definition: "Tool name 'get_response_body' indicates retrieval of HTTP response content from a webpage interaction. The sibling tools include browser automation actions (click, evaluate, check_checkbox) and data clearing operations, positioning this tool as a data…" ## Use case AI agents call get_response_body to retrieve information from Playwright MCP Server 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 Playwright MCP Server: ```json { "version": "1", "default": "deny", "tools": { "get_response_body": {} } } ``` ## Other tools on Playwright MCP Server (66) - `clear_cookies` — Destructive — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/clear-cookies.md - `clear_network_logs` — Destructive — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/clear-network-logs.md - `clear_storage` — Destructive — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/clear-storage.md - `apply_antidetect_preset` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/apply-antidetect-preset.md - `check_checkbox` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/check-checkbox.md - `clear_text` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/clear-text.md - `click` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/click.md - `evaluate` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/evaluate.md - `fill` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/fill.md - `go_back` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/go-back.md - `go_forward` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/go-forward.md - `hover` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/hover.md - `intercept_route` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/intercept-route.md - `navigate` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/navigate.md - `press_key` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/press-key.md - `recreate_context` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/recreate-context.md - `reload` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/reload.md - `restart_browser` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/restart-browser.md - `scroll` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/scroll.md - `select_option` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/select-option.md - `set_extra_headers` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/set-extra-headers.md - `set_user_agent` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/set-user-agent.md - `set_viewport_size` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/set-viewport-size.md - `switch_page` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/switch-page.md - `switch_to_latest_page` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/switch-to-latest-page.md - `type_text` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/type-text.md - `uncheck_checkbox` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/uncheck-checkbox.md - `unroute_all` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/unroute-all.md - `upload_file` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/upload-file.md - `wait_for_element` — Execute — https://policylayer.com/tools/alexrwilliam-playwright-mcp-server/wait-for-element.md - …and 36 more: https://policylayer.com/tools/alexrwilliam-playwright-mcp-server.md ## For agents This record is a snapshot.
