Multi-Model Orchestrator MCP Server

An intelligent Model Context Protocol (MCP) server that automatically routes queries to the most suitable AI model based on task requirements, cost constraints, and performance characteristics.

Features

• Intelligent Routing: Automatically analyzes queries to determine task type (coding, analysis, creative writing, etc.)
• Cost Optimization: Recommends models based on budget constraints and cost-per-token
• Performance Tiers: Supports premium, standard, fast, and budget model tiers
• Multi-Provider: Includes models from OpenAI, Anthropic, Google, and open-source options
• Flexible Priorities: Optimize for cost, performance, speed, or balanced approach
• Model Comparison: Side-by-side comparison of different models
• Cost Estimation: Calculate estimated costs before running queries

# Query: "Analyze this codebase and suggest architectural improvements"
# Priority: performance
# Result: gpt-4 or claude-3-opus (premium tier, strong reasoning)

Example 3: Speed-Optimized Simple Chat

# Query: "What's the weather like?"
# Priority: speed
# Result: gpt-3.5-turbo or claude-3-haiku (fast response)

Example 4: Budget Constraint

# Query: "Write a blog post about AI"
# Priority: balanced
# max_cost_per_1k: 0.005
# Result: claude-3-sonnet or gemini-pro (within budget, good quality)

Task Type Detection

The orchestrator automatically detects task types:

• Coding: Keywords like "code", "function", "debug", "programming"
• Analysis: Keywords like "analyze", "compare", "evaluate"
• Creative: Keywords like "write", "story", "poem", "creative"
• Math: Keywords like "calculate", "math", "solve"
• Translation: Keywords like "translate", "translation"
• Summarization: Keywords like "summarize", "summary", "brief"
• Reasoning: Keywords like "reasoning", "logic", "explain why"
• Chat: Default for general conversation

Resources

The server provides two resources:

1. models://catalog - Complete model catalog with capabilities
2. models://routing-rules - Current routing rules and logic

Customization

Adding New Models

Edit the MODELS dictionary in multi_model_orchestrator.py:

MODELS = {
    "your-model-name": ModelInfo(
        name="your-model-name",
        provider="YourProvider",
        tier=ModelTier.STANDARD,
        cost_per_1k_tokens=0.005,
        strengths=["coding", "analysis"],
        max_tokens=8192,
        supports_vision=False,
        supports_function_calling=True
    )
}

Adjusting Routing Logic

Modify the recommend_model() method to adjust scoring:

# Increase weight for task type matching
if task_type.value in model_info.strengths:
    score += 50  # Adjust this value

Future Enhancements

• Real-time cost tracking
• Usage analytics and reporting
• A/B testing between models
• Custom routing rules via configuration
• Integration with actual API providers
• Model performance benchmarking
• Historical query analysis
• Rate limiting support
• Multi-model ensemble responses

Testing

Test the server manually:

# Run the server
python multi_model_orchestrator.py

# In another terminal, test with MCP Inspector
npx @modelcontextprotocol/inspector python multi_model_orchestrator.py

Troubleshooting

Server won't start

• Ensure Python 3.10+ is installed
• Check that all dependencies are installed: pip install -r requirements.txt
• Verify the script path in your configuration

No models recommended

• Check that your query is being analyzed correctly
• Try different priority modes
• Verify max_cost constraints aren't too restrictive

Tool calls failing

• Ensure proper JSON format for parameters
• Check the MCP client logs for detailed error messages

Contributing

To extend this MCP server:

1. Add new models to the MODELS dictionary
2. Enhance task type detection in analyze_query()
3. Adjust scoring logic in recommend_model()
4. Add new tools to handle additional use cases
