Task Master provides an MCP server that Claude Code can connect to. Configure in .mcp.json:

{
  "mcpServers": {
    "task-master-ai": {
      "command": "npx",
      "args": ["-y", "--package=task-master-ai", "task-master-ai"],
      "env": {
        "ANTHROPIC_API_KEY": "your_key_here",
        "PERPLEXITY_API_KEY": "your_key_here",
        "OPENAI_API_KEY": "OPENAI_API_KEY_HERE",
        "GOOGLE_API_KEY": "GOOGLE_API_KEY_HERE",
        "XAI_API_KEY": "XAI_API_KEY_HERE",
        "OPENROUTER_API_KEY": "OPENROUTER_API_KEY_HERE",
        "MISTRAL_API_KEY": "MISTRAL_API_KEY_HERE",
        "AZURE_OPENAI_API_KEY": "AZURE_OPENAI_API_KEY_HERE",

# Create or obtain PRD, then parse it
task-master parse-prd .taskmaster/docs/prd.txt

# Analyze complexity and expand tasks
task-master analyze-complexity --research
task-master expand --all --research

If tasks already exist, another PRD can be parsed (with new information only!) using parse-prd with --append flag. This will add the generated tasks to the existing list of tasks..

# Start each session
task-master next                           # Find next available task
task-master show <id>                     # Review task details

# During implementation, check in code context into the tasks and subtasks
task-master update-subtask --id=<id> --prompt="implementation notes..."

# Complete tasks
task-master set-status --id=<id> --status=done

For complex projects, use multiple Claude Code sessions:

# Terminal 1: Main implementation
cd project && claude

# Terminal 2: Testing and validation
cd project-test-worktree && claude

# Terminal 3: Documentation updates
cd project-docs-worktree && claude

Create .claude/commands/taskmaster-next.md:

Find the next available Task Master task and show its details.

Steps:

1. Run `task-master next` to get the next task
2. If a task is available, run `task-master show <id>` for full details
3. Provide a summary of what needs to be implemented
4. Suggest the first implementation step

Create .claude/commands/taskmaster-complete.md:

Complete a Task Master task: $ARGUMENTS

Steps:

1. Review the current task with `task-master show $ARGUMENTS`
2. Verify all implementation is complete
3. Run any tests related to this task
4. Mark as complete: `task-master set-status --id=$ARGUMENTS --status=done`
5. Show the next available task with `task-master next`

Add to .claude/settings.json:

{
  "allowedTools": [
    "Edit",
    "Bash(task-master *)",
    "Bash(git commit:*)",
    "Bash(git add:*)",
    "Bash(npm run *)",
    "mcp__task_master_ai__*"
  ]
}

At least one of these API keys must be configured:

• ANTHROPIC_API_KEY (Claude models) - Recommended
• PERPLEXITY_API_KEY (Research features) - Highly recommended
• OPENAI_API_KEY (GPT models)
• GOOGLE_API_KEY (Gemini models)
• MISTRAL_API_KEY (Mistral models)
• OPENROUTER_API_KEY (Multiple models)
• XAI_API_KEY (Grok models)

An API key is required for any provider used across any of the 3 roles defined in the models command.

# Interactive setup (recommended)
task-master models --setup

# Set specific models
task-master models --set-main claude-3-5-sonnet-20241022
task-master models --set-research perplexity-llama-3.1-sonar-large-128k-online
task-master models --set-fallback gpt-4o-mini

• Main tasks: 1, 2, 3, etc.
• Subtasks: 1.1, 1.2, 2.1, etc.
• Sub-subtasks: 1.1.1, 1.1.2, etc.

• pending - Ready to work on
• in-progress - Currently being worked on
• done - Completed and verified
• deferred - Postponed
• cancelled - No longer needed
• blocked - Waiting on external factors

{
  "id": "1.2",
  "title": "Implement user authentication",
  "description": "Set up JWT-based auth system",
  "status": "pending",
  "priority": "high",
  "dependencies": ["1.1"],
  "details": "Use bcrypt for hashing, JWT for tokens...",
  "testStrategy": "Unit tests for auth functions, integration tests for login flow",
  "subtasks": []
}

• Use /clear between different tasks to maintain focus
• This CLAUDE.md file is automatically loaded for context
• Use task-master show <id> to pull specific task context when needed

1. task-master show <subtask-id> - Understand requirements
2. Explore codebase and plan implementation
3. task-master update-subtask --id=<id> --prompt="detailed plan" - Log plan
4. task-master set-status --id=<id> --status=in-progress - Start work
5. Implement code following logged plan
6. task-master update-subtask --id=<id> --prompt="what worked/didn't work" - Log progress
7. task-master set-status --id=<id> --status=done - Complete task

For large migrations or multi-step processes:

1. Create a markdown PRD file describing the new changes: touch task-migration-checklist.md (prds can be .txt or .md)
2. Use Taskmaster to parse the new prd with task-master parse-prd --append (also available in MCP)
3. Use Taskmaster to expand the newly generated tasks into subtasks. Consdier using analyze-complexity with the correct --to and --from IDs (the new ids) to identify the ideal subtask amounts for each task. Then expand them.
4. Work through items systematically, checking them off as completed
5. Use task-master update-subtask to log progress on each task/subtask and/or updating/researching them before/during implementation if getting stuck

Task Master works well with gh CLI:

# Create PR for completed task
gh pr create --title "Complete task 1.2: User authentication" --body "Implements JWT auth system as specified in task 1.2"

# Reference task in commits
git commit -m "feat: implement JWT auth (task 1.2)"

# Create worktrees for parallel task development
git worktree add ../project-auth feature/auth-system
git worktree add ../project-api feature/api-refactor

# Run Claude Code in each worktree
cd ../project-auth && claude    # Terminal 1: Auth work
cd ../project-api && claude     # Terminal 2: API work

# Check API keys are configured
cat .env                           # For CLI usage

# Verify model configuration
task-master models

# Test with different model
task-master models --set-fallback gpt-4o-mini

• Check .mcp.json configuration
• Verify Node.js installation
• Use --mcp-debug flag when starting Claude Code
• Use CLI as fallback if MCP unavailable

# Regenerate task files from tasks.json
task-master generate

# Fix dependency issues
task-master fix-dependencies

DO NOT RE-INITIALIZE. That will not do anything beyond re-adding the same Taskmaster core files.

These commands make AI calls and may take up to a minute:

• parse_prd / task-master parse-prd
• analyze_project_complexity / task-master analyze-complexity
• expand_task / task-master expand
• expand_all / task-master expand --all
• add_task / task-master add-task
• update / task-master update
• update_task / task-master update-task
• update_subtask / task-master update-subtask

• Never manually edit tasks.json - use commands instead
• Never manually edit .taskmaster/config.json - use task-master models
• Task markdown files in tasks/ are auto-generated
• Run task-master generate after manual changes to tasks.json

• Use /clear frequently to maintain focused context
• Create custom slash commands for repeated Task Master workflows
• Configure tool allowlist to streamline permissions
• Use headless mode for automation: claude -p "task-master next"

• Use update --from=<id> to update multiple future tasks
• Use update-task --id=<id> for single task updates
• Use update-subtask --id=<id> for implementation logging

• Add --research flag for research-based AI enhancement
• Requires a research model API key like Perplexity (PERPLEXITY_API_KEY) in environment
• Provides more informed task creation and updates
• Recommended for complex technical tasks

This guide ensures Claude Code has immediate access to Task Master's essential functionality for agentic development workflows.
