File-backed MCP server for hierarchical project management (Projects → Epics → Features → Tasks)

Trellis MCP

File-backed MCP server for hierarchical project management (Projects → Epics → Features → Tasks).

Overview

Trellis MCP implements the "Trellis MCP v 1.0" specification, providing a structured approach to project planning and task management. The server stores all state as Markdown files with YAML front-matter in a nested tree structure:

planning/projects/P-…/epics/E-…/features/F-…/tasks-open/T-….md

Installation

Install the package in development mode:

uv pip install -e .

Quick Start

1 · Zero‑install (run directly from PyPI)

# 1) install uv once
curl -LsSf https://astral.sh/uv/install.sh | sh
# 2) run the server (STDIO transport)
uvx task-trellis-mcp serve
# 3) optional – HTTP transport on port 8545
uvx task-trellis-mcp serve --http 0.0.0.0:8545

2 · Zero‑install from GitHub

uvx --from git+https://github.com/langadventurellc/trellis-mcp.git task-trellis-mcp serve

Add --http to expose HTTP.

3 · Local development workflow (editable clone)

1. Initialize a new planning structure:

   uv run task-trellis-mcp init
   

2. Start the MCP server:

   # STDIO transport (default)
   uv run task-trellis-mcp serve
   
   # HTTP transport
   uv run task-trellis-mcp serve --http localhost:8000
   

3. Create objects with priority fields:

   # Task with high priority
   kind: task
   id: T-setup-auth
   title: Set up authentication system
   priority: high
   status: open
   
   # Feature with normal priority (default)
   kind: feature  
   id: F-user-management
   title: User management system
   priority: normal
   status: open
   

4. Test RPC methods with mcp-inspector:

   # Start mcp-inspector to test your server
   npx @modelcontextprotocol/inspector node -e "require('child_process').spawn('task-trellis-mcp', ['serve'], {stdio: 'inherit'})"
   
   # Or test with CLI mode to call getNextReviewableTask
   npx @modelcontextprotocol/inspector --cli task-trellis-mcp serve --method tools/call --tool-name getNextReviewableTask --tool-arg projectRoot=.
   

   Example output when reviewable task found:

   {
     "task": {
       "id": "implement-auth",
       "title": "Implement authentication system", 
       "status": "review",
       "priority": "high",
       "parent": "F-user-management",
       "file_path": "./planning/projects/P-app/epics/E-auth/features/F-user-management/tasks-open/T-implement-auth.md",
       "created": "2025-01-15T10:00:00Z",
       "updated": "2025-01-15T14:30:00Z"
     }
   }
   

   Example output when no reviewable tasks exist:

   {
     "task": null
   }
   

5. Delete objects with cascade deletion:

   # Delete a task (no children to cascade)
   task-trellis-mcp delete task T-001
   
   # Delete a feature with confirmation prompt
   task-trellis-mcp delete feature F-user-management
   # Output: ⚠️  Delete Feature F-user-management and 5 descendants? [y/N]
   
   # Delete an epic and all its children
   task-trellis-mcp delete epic E-auth
   # Output: ⚠️  Delete Epic E-auth and 12 descendants? [y/N]
   
   # Force delete even if children have protected status (in-progress/review)
   task-trellis-mcp delete project P-001 --force
   

   Example output after successful deletion:

   ✓ Deleted epic E-auth
     Cascade deleted 12 items:
       - planning/projects/P-001/epics/E-auth/epic.md
       - planning/projects/P-001/epics/E-auth/features/F-login/feature.md
       - planning/projects/P-001/epics/E-auth/features/F-login/tasks-open/T-login-form.md
       - planning/projects/P-001/epics/E-auth/features/F-login/tasks-done/2025-01-15T10:30:00-T-setup-db.md
       - ... (and 8 more files)
   

6. Run from test.pypi.org:

  --prerelease allow \
  --index-url https://test.pypi.org/simple/ \
  --extra-index-url https://pypi.org/simple/ \
  task-trellis-mcp==1.0.0rc1 serve
