Code Council

Your AI Code Review Council - Get diverse perspectives from multiple AI models in parallel.

An MCP (Model Context Protocol) server that provides AI-powered code review using multiple models from OpenRouter. Think of it as assembling a council of AI experts to review your code, each bringing their unique perspective.

Features

• 🔍 Multi-Model Code Review - Get diverse perspectives by running reviews across multiple AI models simultaneously
• 🎨 Frontend Review - Specialized reviews for accessibility, performance, and UX
• 🔒 Backend Review - Security, architecture, and performance analysis
• 📋 Plan Review - Review implementation plans before writing code
• 📝 Git Changes Review - Review staged, unstaged, branch diffs, or specific commits
• ⚡ Parallel Execution - All models run concurrently for fast results

Quick Start

Using with npx (Recommended)

The easiest way to use this MCP server is via npx. Configure your MCP client with environment variable for the API key:

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "code-council": {
      "command": "npx",
      "args": ["-y", "@klitchevo/code-council"],
      "env": {
        "OPENROUTER_API_KEY": "your-api-key-here"
      }
    }
  }
}

With custom models:

{
  "mcpServers": {
    "code-council": {
      "command": "npx",
      "args": ["-y", "@klitchevo/code-council"],
      "env": {
        "OPENROUTER_API_KEY": "your-api-key-here",
        "CODE_REVIEW_MODELS": ["anthropic/claude-sonnet-4.5", "openai/gpt-4o"],
        "FRONTEND_REVIEW_MODELS": ["anthropic/claude-sonnet-4.5"],
        "BACKEND_REVIEW_MODELS": ["openai/gpt-4o", "google/gemini-2.0-flash-exp"]
      }
    }
  }
}

Cursor

Add to your Cursor MCP settings (.cursor/mcp.json or similar):

{
  "mcpServers": {
    "code-council": {
      "command": "npx",
      "args": ["-y", "@klitchevo/code-council"],
      "env": {
        "OPENROUTER_API_KEY": "your-api-key-here"
      }
    }
  }
}

Other MCP Clients

For any MCP client that supports environment variables:

{
  "command": "npx",
  "args": ["-y", "@klitchevo/code-council"],
  "env": {
    "OPENROUTER_API_KEY": "your-openrouter-api-key"
  }
}

Installation (Alternative)

If you prefer to install globally:

npm install -g @klitchevo/code-council

Then configure without npx:

{
  "mcpServers": {
    "code-council": {
      "command": "@klitchevo/code-council",
      "env": {
        "OPENROUTER_API_KEY": "your-api-key-here"
      }
    }
  }
}

Getting an API Key

1. Sign up at OpenRouter
2. Go to Keys in your dashboard
3. Create a new API key
4. Add credits to your account at Credits

Security Best Practices

⚠️ CRITICAL SECURITY WARNING: Never commit your OpenRouter API key to git!

MCP Config File Locations (Safe - Not in Git)

MCP client configurations are stored outside your project directory and won't be committed:

• Claude Desktop:
  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
  • Linux: ~/.config/Claude/claude_desktop_config.json
• Cursor: Global settings (not in project)
• Other MCP Clients: Typically in user config directories

These files are safe to put your API key in because they're not in your git repository.

✅ SAFE:

• Putting the API key in MCP client config files (they're outside git)
• Using system environment variables and referencing them
• Keeping configs in user directories (~/.config/, ~/Library/, etc.)

❌ NEVER DO:

• Don't create .mcp.json or config files inside your project directory
• Don't commit any file containing your API key to git
• Don't share config files containing API keys
• Don't hardcode API keys in code

Using Environment Variables (Extra Security)

For added security, store the key in your shell environment:

# Add to ~/.zshrc or ~/.bashrc
export OPENROUTER_API_KEY="sk-or-v1-..."

Then reference it in your MCP config:

{
  "env": {
    "OPENROUTER_API_KEY": "${OPENROUTER_API_KEY}"
  }
}

list_review_config

Configuration

Customizing Models

You can customize which AI models are used for reviews by setting environment variables in your MCP client configuration. Each review type can use different models.

Available Environment Variables:

• CODE_REVIEW_MODELS - Models for general code reviews
• FRONTEND_REVIEW_MODELS - Models for frontend reviews
• BACKEND_REVIEW_MODELS - Models for backend reviews
• PLAN_REVIEW_MODELS - Models for plan reviews
• TEMPERATURE - Control response randomness (0.0-2.0, default: 0.3)
• MAX_TOKENS - Maximum response tokens (default: 16384)

Format: Model arrays use JSON array format

Example:

{
  "mcpServers": {
    "code-council": {
      "command": "npx",
      "args": ["-y", "@klitchevo/code-council"],
      "env": {
        "OPENROUTER_API_KEY": "your-api-key",
        "CODE_REVIEW_MODELS": ["anthropic/claude-sonnet-4.5", "openai/gpt-4o", "google/gemini-2.0-flash-exp"],
        "FRONTEND_REVIEW_MODELS": ["anthropic/claude-sonnet-4.5"],
        "BACKEND_REVIEW_MODELS": ["openai/gpt-4o", "anthropic/claude-sonnet-4.5"],
        "TEMPERATURE": "0.5",
        "MAX_TOKENS": "32000"
      }
    }
  }
}

Default Models: If you don't specify models, the server uses these defaults:

• minimax/minimax-m2.1
• z-ai/glm-4.7
• x-ai/grok-code-fast-1

Finding Models: Browse all available models at OpenRouter Models. Popular choices include:

• anthropic/claude-sonnet-4.5 - Latest Sonnet, excellent for code review
• anthropic/claude-opus-4.5 - Frontier reasoning model for complex tasks
• openai/gpt-4o - Latest GPT-4 Omni model
• google/gemini-2.0-flash-exp - Fast and affordable
• meta-llama/llama-3.3-70b-instruct - Latest open source option

Local Development

1. Clone the repository:

git clone <your-repo-url>
cd multi-agent

2. Install dependencies:

npm install

3. Create .env file:

cp .env.example .env
# Edit .env and add your OPENROUTER_API_KEY

4. Build:

npm run build

5. Run:

npm start
# or use the convenience script:
./run.sh

6. For development with auto-rebuild:

npm run dev

How It Works

1. The MCP server exposes tools that Claude (or other MCP clients) can call
2. When you ask Claude to review code, it calls the appropriate tool
3. The server sends your code to multiple AI models via OpenRouter in parallel
4. Results from all models are aggregated and returned
5. Claude presents you with diverse perspectives from different AI models

Cost Considerations

• Each review runs across multiple models simultaneously
• Costs vary by model - check OpenRouter pricing
• You can reduce costs by:
  • Using fewer models in your configuration
  • Choosing cheaper models
  • Using specific review_type options instead of full reviews
  • Lowering MAX_TOKENS (default: 16384) for shorter responses

Troubleshooting

"OPENROUTER_API_KEY environment variable is required"

Make sure you've added the API key to the env section of your MCP client configuration, not just in a separate .env file.

Reviews are slow

• This is expected when using multiple models in parallel
• Consider using fewer models or faster models
• Check OpenRouter status at status.openrouter.ai

Models returning errors

• Check that you have sufficient credits in your OpenRouter account
• Some models may have rate limits or temporary availability issues
• The server will show which models succeeded and which failed

Requirements

• Node.js >= 18.0.0
• OpenRouter API key
• MCP-compatible client (Claude Desktop, Cursor, etc.)
