متغيرات البيئة

• PLATFORM Platform: browser (default) or node for Node.js backend debugging.
• PORT Port for HTTP transport.
• SESSION_IDLE_SECONDS Idle session timeout (seconds).
• SESSION_IDLE_CHECK_SECONDS Interval for checking idle sessions (seconds).
• SESSION_CLOSE_ON_SOCKET_CLOSE Close session when socket closes.
• CONSOLE_MESSAGES_BUFFER_SIZE Maximum console messages to buffer.
• HTTP_REQUESTS_BUFFER_SIZE Maximum HTTP requests to buffer.
• BROWSER_SERVER_INSTRUCTIONS_ENABLE When true, include server instructions in MCP server info (browser platform). Default: true.
• BROWSER_POLICY_UI_DEBUGGING_ENABLE When true, include UI_DEBUGGING_POLICY in server policies (browser platform). Default: false.
• BROWSER_HEADLESS_ENABLE Run browser in headless mode.
• BROWSER_PERSISTENT_ENABLE Use persistent browser context (preserves cookies, localStorage, extensions).
• BROWSER_CDP_ENDPOINT_URL CDP attach: http(s) root or ws(s) URL. Resolves via /json/version, /json/list, or ws /devtools/browser (Chrome 136+). Mutually exclusive with BROWSER_PERSISTENT_ENABLE.
• BROWSER_CDP_ENABLE When true and no BROWSER_CDP_ENDPOINT_URL: probe 127.0.0.1:9222 then :9229 for CDP. Else use BROWSER_CDP_ENDPOINT_URL or default http://127.0.0.1:9222.
• BROWSER_CDP_OPEN_INSPECT On loopback CDP failure, if Chrome is running, open chrome://inspect/#remote-debugging. Default true. Set false to disable.
• BROWSER_PERSISTENT_USER_DATA_DIR Directory for persistent browser context user data.
• BROWSER_USE_INSTALLED_ON_SYSTEM Use system-installed Chrome browser instead of Playwright's bundled browser.
• BROWSER_EXECUTABLE_PATH Custom browser executable path.
• BROWSER_CHROMIUM_SANDBOX When false, launches Chromium with --no-sandbox. Required for Docker/Lambda/CI.
• BROWSER_LAUNCH_ARGS Extra Chromium launch args (comma-separated).
• BROWSER_ALLOWED_DOMAINS Comma-separated list of allowed hostnames. When set, all requests to non-matching hosts are aborted. Subdomains match automatically.

• OTEL_SERVICE_NAME OpenTelemetry service name.
• OTEL_SERVICE_VERSION OpenTelemetry service version.
• OTEL_ASSETS_DIR Directory containing OpenTelemetry bundle files.
• OTEL_INSTRUMENTATION_USER_INTERACTION_EVENTS User interaction events to instrument (comma-separated, e.g., "click,submit").
• OTEL_EXPORTER_TYPE OpenTelemetry exporter type: "otlp/http", "console", or "none".
• OTEL_EXPORTER_HTTP_URL OpenTelemetry collector base URL (e.g., "http://localhost:4318").

• AWS_REGION AWS region for Bedrock usage.
• AWS_PROFILE AWS profile name for Bedrock usage.
• AMAZON_BEDROCK_ENABLE Enable Amazon Bedrock usage.
• AMAZON_BEDROCK_IMAGE_EMBED_MODEL_ID Amazon Bedrock image embedding model ID.
• AMAZON_BEDROCK_TEXT_EMBED_MODEL_ID Amazon Bedrock text embedding model ID.
• AMAZON_BEDROCK_VISION_MODEL_ID Amazon Bedrock vision model ID.
• FIGMA_ACCESS_TOKEN سري Figma API access token for design comparison.
• FIGMA_API_BASE_URL Figma API base URL.
• DAEMON_PORT Daemon mode port (CLI).
• DAEMON_SESSION_IDLE_SECONDS Daemon mode idle session timeout (seconds).
• DAEMON_SESSION_IDLE_CHECK_SECONDS Daemon mode idle session check interval (seconds).

• NODE_POLICY_DEBUGGING_ENABLE When true, include NODE_DEBUGGING_POLICY in server policies (node platform). Default: false.
• NODE_INSPECTOR_HOST Inspector host for debug_connect when MCP runs in Docker (e.g. host.docker.internal). Default: 127.0.0.1.
• TOOL_OUTPUT_SCHEMA_DISABLE When true, omit tool output schema from MCP tool registration (can reduce token usage for some clients).
• AVAILABLE_TOOL_DOMAINS Comma-separated tool domains to enable (e.g. navigation,interaction,a11y,scenario). Unset = all tools. Browser: a11y, content, debug, figma, interaction, navigation, o11y, react, scenario, run, stub, sync. Node: debug, run.
• WORKING_DIR Working directory for project-level config (.browser-devtools-mcp/). Default: process.cwd().
• SEARCH_STRATEGY Search strategy: SIMPLE (default, minisearch + stemmer) or FTS5 (better-sqlite3, optional dep).
• SCENARIO_SEARCH_STRATEGY Override SEARCH_STRATEGY for scenario search only.
