OpenDia is an open source browser extension developed based on the Model Context Protocol (MCP) protocol, specifically designed to bridge AI models to interact with browsers. The project uses the MIT license, the code is completely open on the GitHub platform, allowing developers to freely modify and contribute. Its core technology lies in the MCP protocol, which establishes a WebSocket communication pipeline between locally running servers and browser extensions, using port 5555 by default.
The core value of the tool is reflected in:
- Localized operation mechanism to ensure user data privacy and security
- Standardized protocols support multiple mainstream AI models (e.g., Claude, ChatGPT, etc.)
- Cross-browser support including Chrome, Firefox, Edge and other major browsers
- Remote control and stabilization capabilities have been implemented in v1.1
The project implementation relies on the Node.js environment (v14+) as the underlying runtime platform, with dependency management and service deployment via the npm package management system. This technical architecture allows OpenDia to have the scalability of a professional-grade tool while maintaining the ease of use for individual users.
