An MCP server that helps AI coding agents break down projects into tasks and track their progress.
npm install @langadventurellc/task-trellis-mcpProject planning and task management built specifically for AI agents
Task Trellis is an MCP server for project planning and task management built specifically for AI agents. It helps by breaking down complex projects and tracking their progress with built-in task management, complete with progress tracking, dependency management, and workflow automation. By default, all data is stored locally in Markdown files.
Primarily built as a much better alternative to managing markdown checklists. Task Trellis will make it easier to define requirements, specifications, and tasks in a structured way that the agents can actually use directly.
Full documentation is available in the docs folder.

| Prompt | Result |
| ------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------ |
| /task-trellis:create-project (my project details) | _project created with epics, features and tasks defined and dependencies identified_ |
| Complete the next available task | _next open task with dependencies satisfied is claimed and worked on_ |
| Work on all of the tasks for feature F-my-feature | _all tasks for the specified feature are claimed and worked on_ |
| Show me all open tasks in (my project) | _list of all open tasks in the specified project_ |
| After working on (feature), there's a bug. Look at what changed and fix it. | _bug identified by examining all the files that were modified while working on that feature and fixed_ |
| /task-trellis:create-features (feature details). Look at (other feature) and follow the same pattern | _new feature created by mirroring the pattern of the other feature_ |
| (after finding issue with design) Update all tasks in F-my-feature and update the design specifications | _all tasks in the specified feature are updated to reflect the new design specifications_ |
- AI agents lose track of complex, multi-step projects
- Agents spin out of control with no clear task structure
- Tasks are often too large or vague, leading to confusion
- No way to manage dependencies or prerequisites
- No visibility into what's been completed vs. what's pending
- Tasks get forgotten, duplicated, or done out of order
- Zero coordination between multiple AI sessions
- Complex projects become chaotic and overwhelming
- Structured Breakdown: Automatically organize projects into hierarchical tasks (depending on the size of the effort required)
- Project → Epic → Feature → Task
- See Picking a Parent Issue Type
- Smart Dependencies: Prevent tasks from starting until prerequisites are complete
- Progress Tracking: Real-time visibility into what's done, in-progress, and pending
- Session Continuity: Pick up exactly where you left off across AI conversations
- Workflow Management: Built-in task claiming, completion, and validation workflows
- File Change Tracking: Automatic documentation of what files were modified for each task
- Learn from History: AI agents can reference past work to inform future tasks
Focused Execution: AI agents work on one clearly-defined task at a time
Progress Visibility: Always know project status and what's next
Dependency Management: Automatic task ordering based on prerequisites
Audit Trail: Complete history of all work completed and changes made
Multi-Session Support: Seamlessly collaborate across different AI conversations
Productivity Boost: Reduce context switching and eliminate forgotten tasks

1. Create Tasks
- Determine your starting point based on the expected size of your project
- Project - For sprawling initiatives with many moving parts
- Epic - For large feature groupings
- Feature - For specific functionality
- Task - For individual work items
2. Claim & Work on Tasks
- AI agent claims next available task
- Excludes tasks that have incomplete prerequisites
- Grabs the next highest priority available task
- Mark a task as draft if you don't want it to be worked on yet - it won't be claimed when the tool looks for the next available task
- Works on the specific task requirements
- Marks task complete with file changes documented
- Automatically tracks which files were modified
- Logs summary of changes made
- Work done in the future could reference this to better understand the current state of the project
3. Track Progress
- View completed vs. pending work
- See dependency relationships
- Monitor overall project health
See installation instructions.
- create_issue - Create projects, epics, features, or tasks with hierarchical relationships
- update_issue - Modify issue properties, status, priority, or prerequisites
- get_issue - Retrieve detailed issue information with history and relationships
- list_issues - Query and filter issues by type, status, priority, or scope (returns issue summaries)
- delete_issue - Remove issues (with dependency validation)
- replace_issue_body_regex - Make targeted body content edits using regex patterns
- claim_task - Claim available tasks for execution with automatic priority ordering
- complete_task - Mark tasks complete with file change documentation
- get_next_available_issue - Use this tool to find the next available issue that's ready to work on.
- append_issue_log - Add progress notes and status updates to task history (occurs automatically on task completion)
- append_modified_files - Record files modified during task execution with change descriptions (occurs automatically on task completion)
- activate - Initialize the task system (if not configured via command line)
- prune_closed - Clean up old completed/cancelled issues for maintenance
Configuration issues:
- Validate JSON syntax in MCP client configuration
- Ensure absolute paths are used for --projectRootFolder
- Restart your MCP client after configuration changes
- Issues: Report bugs or feature requests
