MCP Task Manager

An intelligent Model Context Protocol (MCP) server that provides sophisticated task management capabilities for AI agents. Features automatic complexity analysis, task breakdown, persistent state management, and agent-friendly parameter preprocessing for seamless AI integration.

🤖 Agent-Friendly Features

The MCP Task Manager is specifically designed to work seamlessly with AI agents like Claude Desktop and Kiro IDE, including multi-agent orchestration environments where multiple AI agents work together on complex projects.

📚 Essential for AI Agents

All agents should review the for proven methodologies that maximize effectiveness:

• Plan and Reflect: Thorough planning before action, reflection after completion
• Use Tools, Don't Guess: Always investigate using available tools rather than making assumptions
• Persist Until Complete: Ensure all exit criteria are met before marking tasks complete

Key agent-friendly improvements include:

✨ Smart Parameter Preprocessing

• Automatic Type Conversion: Converts common agent input patterns before validation
  • String numbers → Numbers: "5" becomes 5
  • JSON strings → Arrays: '["tag1", "tag2"]' becomes ["tag1", "tag2"]
  • Boolean strings → Booleans: "true" becomes true, "yes" becomes true
• Backward Compatible: Existing integrations continue to work without changes
• Performance Optimized: <50ms overhead per request

🎯 Enhanced Error Messages

• Visual Indicators: Clear error formatting with emojis (❌, 💡, 📝)
• Actionable Guidance: Specific suggestions on how to fix validation errors
• Tool-Specific Help: Context-aware error messages based on the tool being used
• Working Examples: Include actual usage examples in error responses

🤝 Multi-Agent Orchestration Support

• Task Dependencies: Set up complex task relationships with prerequisite management
• Ready Task Discovery: Find tasks that are unblocked and ready for parallel execution
• Agent Assignment: Orchestration agents can identify and assign ready tasks to specialized agents
• Parallel Execution: Multiple agents can work on independent tasks simultaneously
• Progress Tracking: Monitor completion status across distributed agent workflows

🔧 Common Agent Patterns Supported

// These all work seamlessly now:
{
  "priority": "5",                    // String number → 5
  "tags": '["urgent", "important"]',  // JSON string → array
  "includeCompleted": "true",         // String boolean → true
  "estimatedDuration": "120"          // String number → 120
}

📊 Validation Improvements

• 80%+ Success Rate: For valid agent input patterns requiring conversion
• Clear Error Guidance: Non-technical error messages with helpful suggestions
• Enum Suggestions: Provides valid options when invalid choices are made
• Multiple Error Handling: Clear formatting when multiple validation issues occur

Before Agent-Friendly Updates:

Error: Expected number, received string at priority

After Agent-Friendly Updates:

❌ priority: Expected number, but received string
💡 Use numbers 1-5, where 5 is highest priority
📝 Example: 5 (highest) to 1 (lowest)

🔧 Common fixes:
1. Use numbers 1-5 for priority
   Example: {"priority": 5}

🤖 Multi-Agent Orchestration

The MCP Task Manager is uniquely designed to support multi-agent environments where an orchestration agent coordinates multiple specialized agents working on different tasks in parallel.

Key Orchestration Features

Task Dependency Management

• Set Prerequisites: Define which tasks must be completed before others can begin
• Prevent Conflicts: Automatic circular dependency detection and prevention
• Workflow Control: Ensure proper task sequencing across multiple agents
• DAG Visualization: Visual representation of task dependencies in multiple formats

Ready Task Discovery

• Find Available Work: Identify tasks with no incomplete dependencies
• Priority Sorting: Get ready tasks sorted by priority and creation time
• Parallel Execution: Multiple agents can work on independent ready tasks simultaneously

Project Analysis & Optimization

• Critical Path Analysis: Identify the longest chain of dependent tasks
• Bottleneck Detection: Find tasks that block multiple others
• Progress Monitoring: Track completion status across distributed workflows
• Visual DAG Analysis: ASCII, DOT (Graphviz), and Mermaid format dependency graphs

Multi-Agent Workflow Example

// 1. Orchestration agent sets up task dependencies
{
  "name": "set_task_dependencies",
  "arguments": {
    "listId": "web-app-project",
    "taskId": "deploy-frontend",
    "dependencyIds": ["build-ui", "run-tests", "code-review"]
  }
}

// 2. Orchestration agent finds ready tasks for assignment
{
  "name": "get_ready_tasks",
  "arguments": {
    "listId": "web-app-project",
    "limit": 5
  }
}
// Returns: ["setup-database", "write-docs", "design-api"]

// 3. Orchestration agent assigns tasks to specialized agents:
// - Database Agent → "setup-database"
// - Documentation Agent → "write-docs"
// - API Agent → "design-api"

// 4. As tasks complete, more become ready for assignment
// 5. Process continues until all tasks are completed

Benefits for Multi-Agent Systems

• Increased Throughput: Multiple agents work in parallel on independent tasks
• Optimal Resource Utilization: No agent waits unnecessarily for blocked tasks
• Intelligent Scheduling: Automatic identification of the most impactful work
• Scalable Coordination: Handles complex projects with hundreds of interdependent tasks
• Fault Tolerance: Failed tasks don't block unrelated work streams

Supported Multi-Agent Patterns

• Specialized Agent Teams: Different agents for frontend, backend, testing, documentation
• Pipeline Processing: Sequential stages with parallel work within each stage
• Feature Teams: Multiple agents working on different features simultaneously
• Quality Gates: Dependency-based approval workflows with multiple reviewers

This makes the MCP Task Manager ideal for:

• Large Development Projects with multiple specialized AI agents
• Content Creation Pipelines with writers, editors, and publishers
• Research Projects with data collection, analysis, and reporting agents
• Business Process Automation with multiple workflow participants
