Kanban Agent

kanban-agent-mcp

Self-hosted kanban board built for AI agents

Node 26 stdlib backend • zero npm dependencies (SQLite) • vanilla JS, no build step MCP server onboard — your agents work the board natively

A single-container kanban board: Node 26 stdlib backend (zero npm dependencies by default — node:http + built-in node:sqlite), vanilla JS frontend with no build step. Visual style inspired by Twenty CRM (accent #4662d5, background #fcfcfc).

Why "for agents"? The board is a shared workspace where AI coding agents (Claude Code, Cursor, Codex, OpenCode, …) act as first-class users: at the planning stage an agent breaks a feature into tasks and puts them on the board; while implementing, it drags cards along the pipeline, leaves progress in the notes, and closes the task when done. The human sees live progress, the agent gets structure instead of a to-do in a chat. Two integration channels are built for this:

1. MCP server (POST /mcp) — 11 kanban_* tools: list projects, stages and tasks, create/update/move/delete tasks, manage assignees. Point any MCP client at the instance URL.
2. REST + bearer tokens — the same operations over plain HTTP: Authorization: Bearer kb_… with read or write scopes; stored tokens are hashed (sha256), every mutation is audited.

More: multi-user access with roles, a setup wizard on first run, dynamic pipeline (columns configured in the UI), optional PostgreSQL.

• Multi-user: administrator account is created in a first-run setup wizard (in the browser, no passwords in env vars or config files); the admin can invite more users (each with their own login/password).
• Dynamic pipeline: kanban columns (stages) are configured in the UI.
• API + MCP: bearer-token automation for agents, MCP server at POST /mcp, audit log.
• Optional PostgreSQL: switch the storage engine via environment variables; SQLite stays the zero-config default.

Quick start (Docker)

docker build -t kanban .
docker volume create kanban_data
docker run -d --name kanban --restart unless-stopped \
  -p 3100:3100 -v kanban_data:/data \
  kanban

Open http://localhost:3100/ — the setup wizard greets you on first run:

1. Pick the interface language (English / Русский / 中文).
2. Create the administrator account (username + password).
3. Start using the board; add users later under Users (admins only).

Optional hardening for exposed instances: -e KANBAN_SETUP_TOKEN=… makes the wizard ask for that token before accepting the administrator account, so a stranger cannot claim your fresh instance first.

docker compose

docker-compose.yml is included. Option A (simplest — volume auto-created): remove external: true from volumes: in the compose file. Option B (explicit, protects against compose-project renames):

docker volume create kanban_data
docker compose up -d

Storage engines

Environment variables:

# either a full connection string
DATABASE_URL=postgres://user:pass@host:5432/kanban

# or individual parts
POSTGRES_HOST=host
POSTGRES_PORT=5432
POSTGRES_USER=user
POSTGRES_PASSWORD=pass
POSTGRES_DB=kanban
POSTGRES_SSL=1        # optional: enable TLS

The schema is created automatically on both engines; migrations are idempotent. To move an existing SQLite installation to PostgreSQL, export with GET /api/export and re-import the JSON into the new instance.

Run without Docker

npm install            # only needed for PostgreSQL mode
KANBAN_PORT=3100 KANBAN_DATA=./data node server.js

Requires Node ≥ 26 (built-in node:sqlite).

MCP for AI agents

The MCP endpoint is POST {URL}/mcp (JSON-RPC 2.0, Streamable HTTP, stateless). Bearer-token auth only — create a token in Agents & tokens.

curl -X POST http://localhost:3100/mcp \
  -H "Authorization: Bearer kb_…" -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Tools: kanban_list_projects, kanban_create_project, kanban_list_tasks, kanban_get_task, kanban_create_task, kanban_update_task, kanban_move_task, kanban_delete_task, kanban_list_members, kanban_list_custom_fields, kanban_list_stages.

Read-scope tokens may call the read tools; mutations (create/update/move/ /delete) require the write scope. Never hardcode stage ids — take them from kanban_list_stages.

Users and roles

Passwords are stored only as scrypt hashes; sessions are HTTP-only cookies stored in the database (they survive restarts and can be revoked).

Agents (automation) authenticate with bearer tokens (Authorization: Bearer kb_…), created in Agents & tokens. Only the sha256 hash of a token is stored; the full value is shown once at creation.

Environment variables

API overview

Human-facing auth: POST /api/login {username, password} → cookie sid. Agent auth: Authorization: Bearer kb_… on /api/* and /mcp.

GET/POST /api/projects          PATCH/DELETE /api/projects/:id (+?archived=0|1|all)
GET/PUT /api/projects/:id/access  {user_ids:[…]} (admin only; PUT = full replace)
GET/POST /api/tasks             GET /api/tasks?project=<id>|none
PATCH/DELETE /api/tasks/:id     POST /api/tasks/:id/move {stage, before_id?|after_id?}
GET /api/tasks/:id
GET/POST /api/stages            PATCH/DELETE /api/stages/:id?reassign=<stage_id>
GET/POST /api/members           PATCH/DELETE /api/members/:id
GET/POST /api/custom-fields     PATCH/DELETE /api/custom-fields/:id
GET/PATCH /api/view-fields      (per-view column settings)
GET/POST /api/users             PATCH/DELETE /api/users/:id     (admin only)
GET /api/audit                  (admin only)
GET /api/sessions               DELETE /api/sessions/:sid       (admin only)
GET /api/export                 (admin only)
GET/POST /api/tokens            PATCH/DELETE /api/tokens/:id
GET /api/me                     POST /api/setup (while no users exist)

Stages are dynamic: ids come from GET /api/stages. Exactly one stage has is_done: 1 (the finish); completion checks use the flag, not a hardcoded id. project_id: null is a valid location (“No project”).

Tasks accept an optional urgency field ('h' | 'm' | 'l', empty/clears to null) on create/patch — shown as a colored square next to the task number.

Project visibility: admin sessions and bearer tokens see every project; member sessions see only projects granted to them via /api/projects/:id/access (and cannot see “No project” tasks).

Files

Development

The app is three files of vanilla JS with no build step. Style colors live in :root CSS variables (public/style.css); icons are inline SVG in the ICONS object (public/app.js); UI strings live in the I18N dictionary (English is canonical, additions go to all three locales).
