This is an n8n community node package that provides integration with OpenCode AI Server API.

OpenCode is a powerful terminal-based AI coding assistant. This node enables you to interact with OpenCode Server from your n8n workflows.

Features

  • Session Management: Create, list, get, delete, and abort OpenCode sessions
  • Message Operations: Send messages (sync/async), execute commands, run shell commands
  • AI Agent Integration: LangChain-compatible Tool and ChatModel nodes for n8n AI agents
  • Dynamic Configuration: Auto-load available models, agents, and commands from server

Prerequisites

⚠️ Important: This package requires a running OpenCode Server instance. The node connects to OpenCode Server via REST API, so you must have the server running before using this node.

Installing OpenCode

# Install OpenCode CLI
curl -fsSL https://opencode.ai/install | bash

For other installation methods (npm, Homebrew, Scoop, etc.), see the OpenCode Installation Guide.

Oh My OpenCode (Optional, Recommended)

Oh My OpenCode is a powerful plugin that enhances OpenCode with specialized agents like Sisyphus (Claude Opus 4.5 with extended thinking) and parallel background task execution.

# Install via bunx
bunx oh-my-opencode install

# Or via npm
npm install -g oh-my-opencode

For more details, visit Oh My OpenCode GitHub.

Starting OpenCode Server

# Set authentication credentials via environment variables
OPENCODE_SERVER_USERNAME=your_username OPENCODE_SERVER_PASSWORD=your_password opencode serve --port 4096

You can change the port number as needed. The credentials you set here will be used in the n8n credential configuration.

Security Considerations

🔒 Security Warning: The example above is for development/testing purposes only.

For production deployments:

  • Never hardcode credentials in scripts or command lines
  • Use secure environment variable management (e.g., .env files with proper permissions, secrets managers)
  • Deploy behind a reverse proxy (nginx, Caddy) with HTTPS/TLS encryption
  • Implement network-level security (firewall rules, VPN, private networks)
  • Use strong passwords and consider rotating credentials regularly
  • Monitor access logs and set up alerts for suspicious activity

Example production setup with environment file:

# .env file (chmod 600)
OPENCODE_SERVER_USERNAME=secure_username
OPENCODE_SERVER_PASSWORD=strong_random_password

# Start server
source .env && opencode serve --port 4096
