Cline just open-sourced their agent SDK 🤯
They spent the last few months rewriting their entire harness from the ground up.
What you get:
→ File editing, terminal commands, browser use, and MCP servers through a TypeScript API
→ ACP-compatible (Agent Client Protocol)
→ The exact same engine running their VS Code extension, CLI, JetBrains plugin, and Kanban board
npm i @cline/sdk
100% Open Source.

Introducing the Cline SDK. We rebuilt the Cline harness for our extension and CLI from scratch using all the lessons learned since creating one of the world's first coding agents in 2024, and are open sourcing it for others to build with today.
