🚀 DoneTick MCP Server (Model Context Protocol SSE)

A complete, production-ready Model Context Protocol (MCP) server implementing HTTP Server-Sent Events (SSE) for DoneTick (self-hosted chores and task management).

Compatible with Mistral Le Chat, Claude Desktop, LibreChat, n8n, Open WebUI, and any MCP client.

📋 Features

The server provides 57 specialized MCP tools covering the DoneTick API, including completion history and time tracking. Every endpoint is verified against a live instance by npm run smoke.

1. 📝 Chores & Tasks (donetick_*)

• donetick_list_chores: List tasks with filters (search, project, status).

• donetick_get_chore: Full task details — recurrence, assignees, subtasks, labels, triggers — plus lastCompletedDate, lastCompletedBy and timeSpentSeconds.

• donetick_create_chore: Create a chore with due date, recurrence, priority, points, project, subtasks, labels, notifications, approval and sensor triggers.

• donetick_update_chore: Partial or full updates. Aborts rather than writing blind if the chore cannot be read first.

• donetick_complete_chore: Complete a chore and schedule its next recurrence.

• donetick_undo_chore: Undo the last completion.

• donetick_delete_chore: Permanently delete a chore (prefer archiving).

• donetick_set_due_date: Set, change, or clear a due date.

• donetick_set_priority: Set priority — 1 is highest (P1), 4 lowest, 0 none.

• donetick_skip_chore: Skip the current recurrence.

• donetick_nudge_chore: Send a reminder nudge to the assignee.

• donetick_set_chore_notifications: Configure reminders (due date, predue, nagging, completion).

• donetick_set_chore_project, donetick_set_chore_assignee: Reassign a chore.

2. 📊 Completion History (donetick_*)

• donetick_get_chore_history: Every completion, skip, reschedule and miss for one chore, with a readable statusName and a summary. This is the only reliable way to tell "done" from "edited" — updatedAt conflates both.

• donetick_get_history: Circle-wide activity, filterable by date range and status.

• donetick_modify_history_entry: Correct when a completion was logged, or its notes.

• donetick_delete_history_entry: Remove a mistaken entry.

3. ⏱️ Time Tracking (donetick_*)

• donetick_start_chore / donetick_pause_chore: Run the per-chore timer.

• donetick_get_chore_timer: Total time spent plus each work session.

• donetick_reset_chore_timer: Clear the accumulated time.

• donetick_adjust_time_session / donetick_delete_time_session: Correct history after the fact.

4. 🧩 Subtasks (donetick_*)

• donetick_set_subtasks: Replace the whole list. Destructive, but preserves ids and completion state by matching on name.

• donetick_add_subtask: Append one subtask, leaving the others intact.

• donetick_complete_subtask / donetick_uncomplete_subtask: Tick one subtask, by id or by name.

• donetick_remove_subtask: Delete one subtask without rewriting the list.

Note: completing a recurring chore clears its subtasks rather than ticking them. That is DoneTick's own behaviour, readying the next occurrence.

5. 🗄️ Archiving & Approval (donetick_*)

• donetick_list_archived_chores, donetick_archive_chore, donetick_unarchive_chore: Reversible alternative to deletion.

• donetick_approve_chore, donetick_reject_chore: Review completions on chores with requireApproval.

6. 🏷️ Labels & Tags (donetick_*)

• donetick_list_labels: List labels, falling back to extracting them from chores.

• donetick_create_label, donetick_update_label, donetick_delete_label: See the limitation below — these require a JWT.

• donetick_set_chore_labels, donetick_add_chore_label: Attach labels to a chore.

7. ⚡ Smart Things & Event Triggers (donetick_*)

• donetick_list_things, donetick_create_thing, donetick_update_thing, donetick_delete_thing.

• donetick_set_thing_state: Update a sensor or counter, automatically triggering linked tasks.

• donetick_get_thing_history: Every state a thing has held, and when.

• donetick_link_thing_chore / donetick_unlink_thing_chore: Trigger conditions (eq, neq, gt, lt, gte, lte).

8. 📁 Projects (donetick_*)

• donetick_list_projects, donetick_create_project, donetick_update_project, donetick_delete_project.

9. 👥 Circles, Members & Filters (donetick_*)

• donetick_get_circle_info, donetick_list_members, donetick_list_filters.

📅 Dates and priorities

Dates. DoneTick binds every date to a Go time.Time, so it only accepts RFC3339. The connector additionally accepts YYYY-MM-DD and YYYY-MM-DD HH:mm, resolving them in DONETICK_TIMEZONE (default UTC) at DONETICK_DEFAULT_DUE_TIME (default 18:00). Set both if you want "due tomorrow" to mean a sensible local hour rather than midnight UTC.

Priorities. DoneTick counts down: 1 is the highest priority, shown as a red P1 in the web UI, and 4 is the lowest; 0 means no priority. Versions before 2.0.0 documented this backwards, so chores written through the old descriptions may carry inverted values.

⚠️ Known limitations

• Labels cannot be created or edited with an API key. DoneTick mounts /api/v1/labels behind JWT-only middleware, unlike every other route. Reading falls back to extracting labels from chores; manage them in the web UI.

• No arbitrary duration can be logged. POST /chores/{id}/do accepts no time-spent value, and DoneTick's manual-duration handler is defined but never routed. Use start/pause, or adjust a session's boundaries afterwards.

• History windows are in days. DoneTick's limit is a number of days, not of rows; since/until are applied client-side after the fetch.

🔒 Security & OWASP Hardening

• OWASP A01 & A07 (Access Control & Timing Attacks): Constant-time authentication token validation (crypto.timingSafeEqual).

• OWASP A02 (Cryptographic Failures & Information Leakage): Secret redaction in logs and safe /health telemetry without credentials.

• OWASP A03 (Injection & SSRF): Strict protocol sanitization (http:, https:) preventing protocol injection or SSRF (file://, gopher://).

• OWASP A04 (Denial of Service): Strict JSON body payload limits (1mb) and active SSE session caps with connection pruning.

• OWASP A05 (Security Misconfiguration): Hardened HTTP headers (X-Content-Type-Options: nosniff, X-Frame-Options: DENY, X-XSS-Protection: 0, Referrer-Policy: no-referrer, X-Powered-By disabled). Non-root Docker execution (USER node).

🐳 Quick Start with Docker

1. Create a docker-compose.yml

      # Resolves date-only inputs such as "2026-08-30" to a local hour
      - DONETICK_TIMEZONE=Europe/Paris
      - DONETICK_DEFAULT_DUE_TIME=18:00
      - MCP_AUTH_TOKEN=
    healthcheck:
      test: ["CMD", "wget", "--no-verbose", "--tries=1", "--spider", "http://localhost:3000/health"]

🧪 Development & Testing

# Install dependencies
npm install

# Run the test suite with coverage.
# Enforces an 80% floor on statements, branches, functions and lines.
npm test

# Build TypeScript
npm run build

# Start local server
npm start

Live smoke test

The unit suite mocks axios, so it proves the payloads are shaped as intended — not that DoneTick accepts them. Before tagging a release, run the smoke test against a real instance:

DONETICK_URL=https://donetick.example DONETICK_TOKEN=xxx npm run smoke

It creates only objects prefixed [mcp-test], exercises every endpoint the connector uses, deletes what it created, and refuses to delete anything lacking that prefix. Existing chores are never modified.
