Arcane Skill

Mode Detection

MCP mode (preferred): Use when mcp__arcane-mcp__arcane tool is available.

HTTP fallback: Use when MCP tools are unavailable. Credentials are available in Bash subprocesses as $CLAUDE_PLUGIN_OPTION_ARCANE_API_URL and $CLAUDE_PLUGIN_OPTION_ARCANE_API_KEY. Do NOT attempt ${user_config.arcane_api_key} in curl — sensitive values only work as $CLAUDE_PLUGIN_OPTION_* in Bash subprocesses.

MCP URL: ${user_config.arcane_mcp_url}

MCP Mode — Tool Reference

Single tool: mcp__arcane-mcp__arcane with action + optional subaction parameters.

Container operations

mcp__arcane-mcp__arcane
  action:    "container"
  subaction: "list" | "get" | "create" | "start" | "stop" | "restart" | "delete" | "stats"
  envId:     (required for most subactions) Environment ID
  id:        (required for get, start, stop, restart, delete, stats) Container ID or name

Volume operations

mcp__arcane-mcp__arcane
  action:    "volume"
  subaction: "list" | "get" | "create" | "delete" | "prune"

Destructive operations — DESTRUCTIVE

The following subactions require confirmation. Will prompt interactively when possible, or require re-call with params: { confirm: true }:

• container:delete — Delete a container
• container:restart — Restart a container
• container:stop — Stop a container
• environment:delete — Remove an environment
• image:delete — Remove an image
• image:prune — Prune unused images
• volume:delete — Remove a volume and its data
• volume:prune — Prune unused volumes
• network:delete — Remove a network
• network:prune — Prune unused networks
• project:down — Stop and remove a project's containers
• project:destroy — Destroy a project
• project:restart — Restart a project
• project:redeploy — Redeploy a project

mcp__arcane-mcp__arcane
  action:    "container"
  subaction: "delete"
  envId:     (required) Environment ID
  id:        (required) Container ID or name
  params:    { confirm: true }

Always confirm with user before executing destructive operations.
