Activepieces Surges to 21,700+ GitHub Stars: Open-Source Zapier Alternative with 400+ MCP Servers for AI Agents

GitHub·medium signal

Activepieces, the MIT-licensed open-source workflow automation platform, is trending with 21,700+ GitHub stars and now exposes all 400+ integrations as MCP servers compatible with Claude Desktop, Cursor, and Windsurf. Every community-contributed piece automatically becomes an MCP tool — meaning any AI coding agent can orchestrate 400+ business integrations natively. This is the open-source play that makes Zapier/Make.com redundant for teams already using AI agents as their primary interface.
