TaskWarriorSAFE
MCP Server for TaskWarrior!
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
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.API

Questions
What is the TaskWarrior MCP server?
MCP Server for TaskWarrior!
What tools does TaskWarrior expose?
3 in total: 2 read-only, 1 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is TaskWarrior safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does TaskWarrior need?
No credential environment variables were found in its source, so it appears to need none.
How does TaskWarrior run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as mcp-server-taskwarrior at 1.0.1.
How current is this page?
The grade is for one exact copy of the source (ba1398db3d5b), read on 2026-10-08. The repository is watched and re-audited when it changes.
