What the publisher says
From the Arcane RMCP repository's README, as published. We do not edit it. Read it on GitHub
arcane-rmcp
Arcane Docker and Compose management over MCP and CLI with authenticated stdio and HTTP.
It exposes one MCP tool, arcane, plus the rarcane CLI. Agents can inspect Arcane environments, manage compose projects, containers, images, networks, volumes, registries, GitOps syncs, image updates, vulnerability findings, and system operations through stdio MCP, Streamable HTTP MCP, or direct shell commands.
30-second path: set RARCANEAPIURL and RARCANEAPIKEY, then run npx -y @dinglebear/rarcane status -> start loopback HTTP with RARCANEMCPHOST=127.0.0.1 npx -y @dinglebear/rarcane serve -> call tools/call with {"action":"status"}.
Status: operational RMCP upstream-client server. Write-capable; destructive Docker and Arcane operations require explicit confirmation. HTTP MCP supports loopback dev mode, static bearer tokens, and Google OAuth through lab-auth.
Not for: replacing Arcane, bypassing Docker or Arcane authorization, running arbitrary shell commands, storing registry or Git credentials, multi-tenant isolation, or passing Arcane API keys through MCP tool arguments.

Naming
The repo and npm package use the upstream service name, while the shipped binary keeps the historical Rust CLI name rarcane. The MCP server may be registered as rarcane, but the tool clients call is arcane.
Capabilities And Boundaries

- Read Arcane status plus Docker environment, project, container, image,
back up supported Arcane resources through action/subaction dispatch.
- Create, update, start, stop, restart, delete, prune, deploy, sync, scan, and
write operations to Arcane.
- Enforce action scopes and destructive-operation confirmation before forwarding
client-side discovery.
