A framework helps you quickly build AI Native IDE products. MCP Client, supports Model Context Protocol (MCP) tools via MCP server.
OpenSumi is a TypeScript framework for building AI-native IDE products that runs in both Electron desktop and browser environments, with starter templates covering cloud IDEs, desktop IDEs, a pure web IDE called CodeBlitz, and a mini-app-style IDE. It functions as an MCP client, meaning it can connect to any Model Context Protocol server and expose its tools directly inside the IDE environment, giving AI assistants access to context and capabilities defined by those servers. The framework integrates with Claude and other AI models through this MCP client layer, supporting the tools feature of the protocol. Developers building custom IDEs or AI-assisted coding environments are the primary audience, and the framework is already used in production by CodeFuse IDE from Alibaba's Ant Group. The modular package structure, published under the `@opensumi` npm namespace, lets teams pick individual IDE components rather than adopting the entire stack at once.
