MCP Gateway Infrastructure Implementation Plan

August 23, 2025 · View on GitHub

Overview

The MCP Gateway Infrastructure serves as a bridge between the Dedalus SDK and various MCP servers, providing hosting, management, and marketplace functionality.

Core Components

1. MCP Server Hosting/Management System

  • MCP Server Manager: Lifecycle management (start, stop, restart, health checks)
  • Server Registry: Track available servers, versions, configurations
  • Resource Management: Memory, CPU, network monitoring for hosted servers
  • Configuration Management: Server-specific settings and environment variables

2. MCP Marketplace Functionality

  • Server Discovery: Automatic detection and registration of new MCP servers
  • Metadata Management: Server descriptions, capabilities, tags, ratings
  • Version Management: Multiple versions, compatibility tracking
  • Search and Filter: Find servers by capability, provider, category

3. Server Lifecycle Management

  • Deployment Pipeline: Automated server installation and setup
  • Health Monitoring: Continuous server health checks and alerting
  • Auto-scaling: Dynamic server scaling based on demand
  • Backup and Recovery: Server state management and disaster recovery

Key Features to Implement

  1. Server Manager

    • Start/stop MCP servers programmatically
    • Monitor server processes and resource usage
    • Automatic restart on failure
    • Configuration validation and management

  2. Marketplace

    • Server metadata storage (SQLite/JSON for now)
    • Search and discovery functionality
    • Rating and review system (basic)
    • Category and tag management

  3. Health Monitoring

    • Periodic health checks for all managed servers
    • Performance metrics collection
    • Alert system for failures
    • Dashboard for monitoring status

  4. API Interface

    • REST endpoints for server management
    • WebSocket for real-time status updates
    • Integration with existing DedalusRunner

Priority Implementation Order

  1. Phase 1: Core Server Manager (Next)

    • Basic server lifecycle management
    • Configuration management
    • Simple health checks

  2. Phase 2: Registry and Discovery

    • Server registry implementation
    • Metadata management
    • Basic marketplace functionality

  3. Phase 3: Advanced Features

    • Health monitoring dashboard
    • Auto-scaling capabilities
    • API endpoints for external integration

Integration with Existing Code

The gateway will integrate with:

  • dedalus_labs/mcp/client.py - Use existing MCP client functionality
  • dedalus_labs/mcp/registry.py - Extend with dynamic server management
  • dedalus_labs/runner.py - Add gateway-aware server selection

Next Steps

  1. Create basic server manager with process management
  2. Implement configuration system for server definitions
  3. Add health monitoring capabilities
  4. Create marketplace metadata management
  5. Build API interface for external access
