Passed 3/3 checks · Runs on your computer · ✓ Commands checked Nov 14, 2026

First: which AI do you use?

Pick your app and the steps appear below.

Works with Claude, with some setup first

You need a Arcane RMCP key (create it on the maker’s site) · 1 setting(s) to fill in (RARCANE_API_URL) · Install Node.js on your computer first (one time) · Only the Claude desktop app (Windows or Mac), not the web or phone

Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server Arcane RMCP for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "rarcane": { "command": "npx", "args": [ "-y", "@dinglebear/rarcane", "mcp" ], "env": { "RARCANE_API_URL": "your-value", "RARCANE_API_KEY": "your-value" } } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) For RARCANE_API_KEY, RARCANE_API_URL, leave "your-value" in place and tell me to paste the real value myself into the file or the app’s field. Never ask me to type a key in chat. 5) Do what we agreed, then check that the Arcane RMCP tools really show up.

This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

  1. Install Node.js (if you don’t have it)

    Already installed? Check first · Open Terminal, type this command and press Enter

    node -v
    • A version number such as v26.13.1 = installed, skip this step
    • "command not found" (on Windows: "is not recognized") = not installed yet, or installed but Terminal needs to be closed and reopened
    How to open Terminal

    Mac: press ⌘ + Space, type Terminal, press Enter

    Windows: open Start, type Windows PowerShell, then Open

    Not installed: Open the official download page, pick the LTS version and the click-through installer: .pkg on Mac · .msi on Windows. Double-click and follow it to the end. No curl command needed

    Open the Node.js download page ↗

    When it’s done, close Terminal, open it again and run the same command. You should see a version number: node -v

    Install once; it works for everything that needs Node.js

  2. Sign up and create a Arcane RMCP key

    Open the maker’s site, sign up and create an API key for the next step. Check the maker’s site for pricing and free plans.

    Open the Arcane RMCP site ↗

  3. Fill in 1 setting(s)

Common questions

Is Arcane RMCP safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: RARCANE_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 13 days ago, and the latest version (0.4.4) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

README from the maker

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

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 RARCANE_API_URL and RARCANE_API_KEY, then run npx -y @dinglebear/rarcane status -> start loopback HTTP with RARCANE_MCP_HOST=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.

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, network, volume, registry, GitOps, update, vulnerability, and system state.
  • Create, update, start, stop, restart, delete, prune, deploy, sync, scan, and back up supported Arcane resources through action/subaction dispatch.
  • Enforce action scopes and destructive-operation confirmation before forwarding write operations to Arcane.
  • Expose the quick_start prompt and rarcane://schema/mcp-tool resource for client-side discovery.
  • Provide setup, doctor, and watch commands for local plugin/runtime checks.

Run the stdio MCP server or CLI without a manual binary install:

npx -y @dinglebear/rarcane --help

npx -y @dinglebear/rarcane mcp npx -y @dinglebear/rarcane status

The npm package downloads rarcane during postinstall. Override download behavior only when testing packaging:

cd rarcane cargo build --release ./target/release/rarcane --help

Minimum supported Rust version: 1.90.

Quickstart

1. Configure Arcane

Point the bridge at an existing Arcane API server:

export RARCANE_API_URL=https://arcane.example.com

export RARCANE_API_KEY=...

The API key is read from env or config only. Do not pass it in MCP tool arguments or CLI --params-json.

2. Run A Safe CLI Call
npx -y @dinglebear/rarcane status
3. Start Loopback HTTP MCP
RARCANE_MCP_HOST=127.0.0.1 npx -y @dinglebear/rarcane serve

In another shell:

curl -sf http://127.0.0.1:40110/health
4. Make A First MCP Call
curl -s -X POST http://127.0.0.1:40110/mcp \

-H "Content-Type: application/json" \ -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"arcane","arguments":{"action":"status"}}}'

Codex / Labby Gateway

Register Arcane through Labby as an HTTP upstream when sharing one long-running server, or run it directly as stdio for local-only use.

[mcp_servers.rarcane]

command = "npx" args = ["-y", "arcane-rmcp", "mcp"]

Generic MCP JSON
{

"command": "rarcane", "args": ["mcp"], "env": { "RARCANE_API_URL": "https://arcane.example.com" } }

Do not put RARCANE_API_KEY, registry credentials, Git credentials, OAuth secrets, SSH keys, passwords, or upstream bearer tokens in MCP tool arguments. Use env, config files, or the MCP client's secret storage. MCP callers never provide credentials, tokens, keys, or secrets as action arguments.

MCP Tool Reference

One MCP tool is exposed: arcane. Pass the required action argument and, for most domains, a required subaction.

Action specs in src/actions.rs and the generated schema notes in docs/MCP_SCHEMA.md are the source of truth for required parameters.

Example read-only tool arguments:

{

"action": "container", "subaction": "list", "envId": "default" }

Example destructive operation:

{

"action": "container", "subaction": "stop", "envId": "default", "id": "my-container", "params": { "confirm": true } }

CLI Reference

rarcane exposes the same service layer as the MCP tool:

rarcane status

rarcane help --domain container rarcane call --action container --subaction list --env-id default rarcane call --action system --subaction docker-info --env-id default rarcane call --action container --subaction stop --env-id default --id my-container --confirm rarcane doctor --json rarcane watch --url http://127.0.0.1:40110 rarcane setup check rarcane setup repair

--params-json accepts action-specific JSON payloads. Do not use it to pass credentials.

Configuration

Host installs read ~/.rarcane/.env, ~/.rarcane/config.toml, and process env. Containers read /data/.env, /data/config.toml, and process env.
