Claude Code ComfyUI Nodes

ComfyUI nodes for integrating Claude Code SDK - enables AI-powered code generation, analysis, and assistance within ComfyUI workflows.

Overview

This node pack provides a stateless, command-based interface to Claude Code within ComfyUI. Unlike traditional chat interfaces, these nodes operate as single-shot commands, making them perfect for automation workflows similar to n8n, Zapier, or Make.

Key Features

• Stateless Command Execution: Each node execution is independent, with explicit memory/context passing
• Folder-Based Output Management: All outputs are organized in timestamped folders
• Context Chaining: Convert previous outputs into memory for subsequent commands
• Argument Substitution: Use variables in commands and memory (e.g., ${PROJECT_NAME})
• Tool Control: Fine-grained control over which tools Claude can use
• Command Library: Pre-built commands in dropdown menu for common tasks
• Memory Templates: Reusable context files for consistent workflows

Installation

1. Ensure you have ComfyUI installed
2. Clone this repository into your ComfyUI/custom_nodes directory
3. Choose your setup:

Option A: Claude Code Max Plan (Recommended)

If you have a Claude Code Max Plan subscription:

• Install Claude Code from https://claude.ai/code
• The "Claude Code Command (Max Plan)" node will use your existing subscription
• No API key needed, no per-token costs

Option B: Developer API

If you want to use the Anthropic API directly:

• Install dependencies: pip install claude-code-sdk aiofiles
• Set your ANTHROPIC_API_KEY environment variable
• Use the "Claude Code Command (API)" node
• Pay per token based on API usage

4. Restart ComfyUI

Usage Examples

Basic Command Execution

1. Add a "Claude Code Execute" node
2. Set command_source to "file" and select a command from dropdown OR set to "text" and enter custom command:

   Create a Python script that generates fibonacci numbers.
   Include error handling and type hints.
   

3. Set model to "sonnet" and max_turns to 8
4. Execute the workflow
5. Check the output folder for generated files

Using Command and Memory Files

1. Place command files in /commands folder (.md or .txt)
2. Place memory/context files in /memories folder
3. Use dropdowns in Execute and Memory Builder nodes
4. Combine with Arguments Builder for dynamic values

Reddit to Video Workflow

1. Add "Claude Reddit Scraper" node
   • Set source to "programming"
   • Set scrape_mode to "comments"
2. Connect output to "Claude Code Execute" node
3. Select "reddit-video-script-simple.md" from command dropdown
4. Execute to generate TikTok/YouTube script

Chaining Commands

1. First Execute node generates code
2. Connect output to "Claude Code Context Builder"
3. Connect memory output to second Execute node
4. Second command references and builds upon the first

Using Arguments

Set arguments as JSON:

{
  "PROJECT_NAME": "MyAwesomeProject",
  "LANGUAGE": "Python"
}

Then use in your command:

Create a ${LANGUAGE} project structure for ${PROJECT_NAME}.
Include README, tests, and proper package structure.

└── src/                        # Node implementations

Output Organization

All outputs are stored in claude_code_outputs/ with timestamped folders:

• Execute node: output_YYYYMMDD_HHMMSS_[id]
• Reddit scraper: reddit_scrape_YYYYMMDD_HHMMSS_[id]
• Each folder contains generated files and _claude_code_metadata.json

Best Practices

1. Be Specific: Clear, detailed commands produce better results
2. Use Context: Chain commands together for complex workflows
3. Manage Tools: Only enable tools that are needed for security
4. Check Outputs: Use the Reader node to verify generated content
5. Template Commands: Save frequently used commands as text files
