casen CLI

casen is an interactive terminal UI (TUI) for managing Camunda 8. Navigate with arrow keys, no flags to memorize.

Installation

pnpm add -g @bpmnkit/cli

Quick Start

casen

The main menu appears. Use ↑ ↓ to navigate, Enter to select, Escape to go back.

Generate BPMN files

casen generate bpmn creates BPMN files from the command line — no interactive menu required. Choose a built-in template, supply a full CompactDiagram JSON definition, or patch an existing file.

casen generate bpmn --template approval --process-id leave-request
casen generate bpmn --input order.bpmn --dump-compact   # inspect as JSON for AI
casen generate bpmn --input order.bpmn --patch '{"elements":[...],"flows":[...]}'

See casen generate for full documentation.

View BPMN, DMN, and Form files

casen view opens a local browser-based viewer. Accepts individual files, folders, or a mix.

casen view bpmn ./processes/     # all .bpmn files in a folder
casen view dmn routing.dmn       # DMN decision table
casen view open ./project/       # any mix of .bpmn/.dmn/.form

See casen view for full documentation.

Connection Profiles

A profile stores the connection details for a Camunda cluster:

# Add a new profile
casen profile add

# You'll be prompted for:
# Name: my-saas-cluster
# Base URL: https://api.cloud.camunda.io
# Auth type: oauth2 | bearer | none
# Client ID, Client Secret, Audience, Token URL (for oauth2)

Profiles are saved to ~/.casen/profiles.json.

Common Workflows

Plugins

casen’s plugin system lets you extend the CLI with new command groups — your own organisation’s workflows, third-party integrations, or community-built tools.

Discover plugins

# Browse all published casen plugins
casen plugin search

# Search by keyword
casen plugin search deploy
casen plugin search slack

Results are fetched live from the npm registry. Any package tagged with the casen-plugin keyword appears here.

Install a plugin

# Install from npm
casen plugin install casen-deploy

# Install a local plugin during development
casen plugin install ./my-plugin

Plugins are installed into ~/.casen/plugins/ and loaded automatically the next time casen starts.

Manage installed plugins

# List installed plugins
casen plugin list

# Show full details for one plugin
casen plugin info casen-deploy

# Update a single plugin to the latest version
casen plugin update casen-deploy

# Update all installed plugins
casen plugin update

# Remove a plugin
casen plugin remove casen-deploy

Once installed, plugin commands appear in the main TUI and in tab-completion alongside built-in commands.

To build your own plugin, see Plugin Authoring.

AIKit Skills

casen ships four Claude Code slash commands for AI-driven process development. Install them into the current project:

casen skills install

Command	Description
`/implement <description>`	Generate BPMN + scaffold workers + validate + deploy
`/review <path>`	Validate a BPMN file and get structured findings
`/test <path>`	Analyse structure, worker coverage, and suggest scenarios
`/deploy <path>`	Deploy a BPMN to local reebe or Camunda 8

See AIKit Skills for full documentation.

Worker commands

# Run a simple auto-complete worker (for testing)
casen worker payment-service

# Start scaffolded workers from ./workers/
casen worker start

# Start a specific scaffolded worker
casen worker start send-invoice

MCP Server Mode

casen can act as an MCP (Model Context Protocol) server, exposing all cluster operations as tools to Claude Desktop, Cursor, or any MCP client:

casen mcp

Configure in Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "camunda": {
      "command": "casen",
      "args": ["mcp"],
      "env": {
        "CAMUNDA_CLIENT_ID": "...",
        "CAMUNDA_CLIENT_SECRET": "..."
      }
    }
  }
}

Now you can ask Claude: “Show me the open incidents on the invoice-approval process” or “Resolve all incidents on process instance 2251799813685249”.
