This Dockerfile enables the chrome-devtools-mcp server to be used with Docker-based MCP registries. It: - Uses Node.js 22 LTS with Chrome dependencies - Installs Chrome Stable for Puppeteer - Builds the TypeScript project - Runs as non-root user for security - Exposes the MCP server via stdio

The entrypoint script checks if BROWSER_URL environment variable is set and only passes --browserUrl flag if it's provided. This allows the MCP registry to support optional browser connection without template issues. Default behavior (no BROWSER_URL): Launches Chrome in headless mode With BROWSER_URL: Connects to existing Chrome instance
Extended entrypoint script to support all configuration options via environment variables: Connection Options: - BROWSER_URL: Connect to existing Chrome via HTTP - WS_ENDPOINT: Connect via WebSocket - WS_HEADERS: Custom headers for WebSocket (JSON) Browser Launch Options: - HEADLESS: true/false (default: true) - VIEWPORT: WIDTHxHEIGHT (default: 1280x720) - ISOLATED: true/false for temporary profile - CHANNEL: stable/canary/beta/dev - EXECUTABLE_PATH: Custom Chrome path - PROXY_SERVER: Proxy configuration - ACCEPT_INSECURE_CERTS: true/false Feature Toggles: - CATEGORY_EMULATION: true/false (default: true) - CATEGORY_PERFORMANCE: true/false (default: true) - CATEGORY_NETWORK: true/false (default: true) Debugging: - LOG_FILE: Path for debug logs

changed the title
Removed the custom entrypoint script since the MCP registry doesn't support conditional command-line argument passing. The server will auto-launch Chrome with default settings (headless, 1280x720). Users who need custom Chrome configurations can build and run the server outside the registry using the standard npx approach with command-line flags.
Simple entrypoint script that converts environment variables to command-line flags only when set: - BROWSER_URL → --browserUrl - WS_ENDPOINT → --wsEndpoint - WS_HEADERS → --wsHeaders This allows the server.yaml to pass these as env vars without causing build errors when they're empty.

This PR adds a Dockerfile to enable the chrome-devtools-mcp server to be used with Docker-based MCP registries.
Changes
Testing
The Dockerfile can be tested by building and running:
docker build -t chrome-devtools-mcp . docker run -i chrome-devtools-mcpThis will enable the server to be added to Docker-based MCP registries like the one at https://github.com/docker/mcp-registry.
