CodeN

What it does

CodeN is an AI-driven programming system that separates state management from LLM reasoning. It uses a central Kernel (the sole writer of state) to orchestrate multiple stateless LLM Workers (Planner, Coder, Critic, Acceptor) to execute complex coding tasks across a codebase.

Tools

• Shell: Execute terminal commands and interact with the OS.
• FS: File system operations for reading and writing code.
• LSP: Structural code analysis including definitions and references.
• grep: Fast string and identifier searching across the repository.
• RAG: Semantic retrieval of codebase context based on successful previous tasks.
• MCP: Dynamic discovery and integration of other MCP servers.

Installation

Since CodeN is a standalone system that can act as an MCP client/server, you can integrate it into Claude Desktop by adding the coden-llm-server sidecar to your config:

{
  "mcpServers": {
    "coden": {
      "command": "go",
      "args": ["run", "github.com/mingzhi1/coden/cmd/coden-llm-server"]
    }
  }
}

Supported hosts

Confirmed support for Claude (via ACP), VS Code, and TUI/CLI environments.
