[BUG] Incomplete MCP Protocol Compliance

[Limeload]

While basic MCP handler exists, it doesn't implement the full MCP protocol for database operations.

Missing Components:

• Proper MCP tool definitions
• MCP resource management
• MCP prompt handling
• Protocol compliance validation

Expected Implementation:

// app/mcp/route.ts - Complete implementation
const handler = createMcpHandler(
  async server => {
    // Database tools
    server.tool('query_database', 'Execute SQL queries', schema, handler);
    server.tool('describe_database', 'Get database schema', schema, handler);
    server.tool('list_databases', 'List user databases', schema, handler);
    
    // Resources
    server.resource('database://{id}/schema', 'Database schema resource');
    
    // Prompts
    server.prompt('query_assistant', 'AI assistant for database queries');
  },
  {
    capabilities: {
      tools: { listChanged: true },
      resources: { subscribe: true },
      prompts: { listChanged: true }
    }
  }
);

Acceptance Criteria:

• Full MCP protocol compliance
• Proper tool, resource, and prompt definitions
• MCP client compatibility testing
• Protocol version compliance
