Overview

What is Chrome MCP Server?

Chrome MCP Server is an implementation of the Model Context Protocol (MCP) designed to interact with Chrome. It was built as a learning exercise to understand the MCP protocol and to provide a server that can be used in Cursor to take screenshots of a page and validate implementation.

How to use Chrome MCP Server?

For the demo implementation, run uv run uvicorn demo_implementation.main:app --reload and connect via the MCP inspector at http://0.0.0.0:8000. For the robust implementation (which uses the MCP Python SDK), start the server with mcp run app/main.py --transport sse and then use the MCP inspector.

Key features of Chrome MCP Server

  • Provides an MCP implementation independent of Anthropic’s library.
  • Supports taking screenshots of a webpage.
  • Allows validation of implementation in Cursor.
  • Includes a demo implementation with initialization over SSE and POST endpoints.
  • Offers a more robust implementation using the MCP Python SDK.

Use cases of Chrome MCP Server

  • Taking screenshots of pages for visual verification.
  • Validating implementation in Cursor during development.
  • Learning the MCP protocol through a hands‑on example.

Frequently asked questions

1

Is Chrome MCP Server a reference implementation of the MCP protocol?

No, it is not a reference implementation. It was built as a learning exercise to understand the protocol.

2

What are the limitations of the demo implementation?

The demo implementation has several limitations, including lack of error handling and inadequate cleanup of sessions.

3

How does the initialization process work in the demo implementation?

Initialization is done in three steps: 1) an initial call to `/sse` to get the session URI, 2) the client sends an `initialize` message, and 3) the client sends a `notifications/initialized` message.

4

What transport does the robust implementation use?

The robust implementation uses SSE (Server‑Sent Events) transport.
