Key Features:

MCP Server: Model Context Protocol v2.0.0 with 26 tools
GraphQL API: Type-safe queries, mutations, and subscriptions
AI Integration: Task breakdown, natural language parsing, schedule optimization
Webhook System: Event-driven automation
Markdown Export: AI-friendly data export
Template Management: Reusable task templates

🔌 Claude Desktop Integration

Quick Setup

Build the MCP server:

npm run build

Configure Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "taskflow": {
      "command": "node",
      "args": [
        "/absolute/path/to/taskflow-graphql/dist/mcp/server.js"
      ],
      "env": {
        "NODE_ENV": "production",
        "AI_API_ENABLED": "false"
      }
    }
  }
}

Restart Claude Desktop
Verify integration:

"List all available tools"
"Create a task titled 'Test Integration'"
