TaskWarrior MCP Server

Node.js server implementing Model Context Protocol (MCP) for TaskWarrior operations.

Features

• View pending tasks
• Filter tasks by project and tags
• Add new tasks with descriptions, due dates, priorities, projects and tags
• Mark tasks as complete

Note: This runs your local task binary, so TaskWarrior needs to be installed and configured!

[!WARNING] This currently uses task id which is an unstable identifier; taskwarrior sometimes renumbers tasks when new ones are added or removed. In the future this should be more careful, using task UUID instead.
