What is Deno 2 Playwright Model Context Protocol Server Example

Deno 2 Playwright Model Context Protocol Server Example

A Model Context Protocol server that provides browser automation capabilities using Playwright. This server enables LLMs to interact with web pages, take screenshots, and execute JavaScript in a real browser environment.

This repo uses Deno 2, which has nice ergonomics, because you can compile a binary and run it without any runtime dependencies.

This code is heavily based on the official Puppeteer MCP server, which you can find here: https://github.com/modelcontextprotocol/servers/tree/main/src/puppeteer

How to build

Only the mac binary build has been tested, but you should be able to build an executable binary for linux x86_64, linux ARM64, and windows x86_64.

  • deno task build-mac
  • deno task build-linux-x86_64
  • deno task build-linux-ARM64
  • deno task build-windows-x86_64

How to run

To invoke the playwright-server binary, you need to update your ~/Library/Application\ Support/Claude/claude_desktop_config.json to point to the binary.

{
  "mcpServers": {
    "playwright": {
      "command": "/path/to/deno2-playwright-mcp-server/playwright-server"
    }
  }
}

Frequently Asked Questions

What is MCP?

MCP (Model Context Protocol) is an open protocol that standardizes how applications provide context to LLMs. Think of MCP like a USB-C port for AI applications, providing a standardized way to connect AI models to different data sources and tools.

What are MCP Servers?

MCP Servers are lightweight programs that expose specific capabilities through the standardized Model Context Protocol. They act as bridges between LLMs like Claude and various data sources or services, allowing secure access to files, databases, APIs, and other resources.

How do MCP Servers work?

MCP Servers follow a client-server architecture where a host application (like Claude Desktop) connects to multiple servers. Each server provides specific functionality through standardized endpoints and protocols, enabling Claude to access data and perform actions through the standardized protocol.

Are MCP Servers secure?

Yes, MCP Servers are designed with security in mind. They run locally with explicit configuration and permissions, require user approval for actions, and include built-in security features to prevent unauthorized access and ensure data privacy.
