Agentcn

agentcn is a registry of complete AI agent recipes distributed with the shadcn command line tool. Instead of importing an opaque agent package, a developer runs one shadcn add command and the full backend source of the agent, including instructions, tools, skills and workflows, is copied into their own project to read, modify and own. It is explicitly not a UI component library; it applies the shadcn copy and paste model to backend agents. It is built for TypeScript developers who want working agent patterns without framework lock in. Recipes target Eve, Vercel's filesystem first framework for durable agents on Vercel Functions; Flue, an agent runtime with subagents, skills and bounded workflows; Mastra; and LangGraph agents built with the Dawn meta framework. The catalogue covers deep web search with cited answers, AI SEO audits, chat with PDF, YouTube or a database, docs chatbots, GitHub pull request review, Slack and Google Sheets agents, a browser agent, meeting notes, customer feedback summaries, flash cards from PDFs and company knowledge assistants. Recipes can also be discovered and installed from an editor through the shadcn MCP server, and the documentation is published in machine readable form for coding agents. agentcn is free to use and publishes no pricing; the project accepts sponsorship. Because recipes are copied as source, there is no runtime dependency on agentcn itself, but the model provider and hosting costs of each agent are the user's own.
