Implement Model Context Protocol (MCP) Support

Overview

This issue proposes implementing support for the Model Context Protocol (MCP) in mycoder, allowing it to connect to MCP servers to access additional context, tools, and prompts when performing tasks.

Background

MCP is a standardized protocol for applications to provide context to Large Language Models (LLMs). It allows for:

1. Resources - Exposing data to LLMs (similar to GET endpoints)
2. Tools - Providing functionality for LLMs to use (similar to POST endpoints)
3. Prompts - Defining reusable templates for LLM interactions
4. Images - Handling image data automatically

Adding MCP support would allow mycoder to connect to various context sources (documentation, databases, APIs) in a standardized way.

Implementation Details

Configuration

Extend the mycoder.config.js file to include MCP configuration:

// mycoder.config.js
export default {
  // Existing config...
  
  // MCP Configuration
  mcp: {
    // MCP Servers to connect to
    servers: [
      {
        name: 'local-database',
        url: 'http://localhost:8000',
        // Optional authentication
        auth: {
          type: 'bearer',
          token: process.env.MCP_SERVER_TOKEN
        }
      }
    ],
    
    // Optional: Default context resources to load
    defaultResources: [
      'schema://main',
      'docs://api/reference'
    ]
  }
};

Core Components

1. MCP Client Module - Create a module to manage connections to MCP servers
2. Config Schema Update - Update configuration to support MCP settings
3. Agent Integration - Modify the agent to use MCP resources and tools
4. CLI Commands - Add commands to interact with MCP servers

Implementation Plan

1. Phase 1: Basic MCP Client

   • Add MCP SDK dependency
   • Implement MCP config schema
   • Create basic MCP client manager

2. Phase 2: Agent Integration

   • Integrate MCP resources with agent context
   • Create adapters for MCP tools
   • Add support for MCP prompts

3. Phase 3: CLI Commands

   • Add MCP-specific CLI commands
   • Implement server management
   • Add resource/tool discovery commands

4. Phase 4: Testing & Documentation

   • Test with sample MCP servers
   • Document MCP features
   • Create examples

Dependencies

• @modelcontextprotocol/sdk - Official TypeScript SDK for MCP
