Cline SDK

Cline open-sourced its SDK, the agent runtime now powering the CLI, VS Code extension, JetBrains plugin, and Kanban board. The SDK enables developers to build custom AI coding agents with their own tools, multi-agent teams, MCP server integrations, scheduled automations, and connector plugins — using the same engine that powers Cline's 61K+ star codebase.
