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.
