What is Arcanon?

Arcanon scans your codebase locally and uploads service dependency results to a shared hub. Your team gets a live service map, instant blast-radius analysis, and drift detection. The results are also exposed to your AI assistant through the bundled MCP server, so Claude can answer cross-repo impact questions without leaving your editor.

Local vs. Team

Arcanon has two surfaces. They share the same data model; you choose how far it travels.

	Local plugin	Arcanon Hub (`app.arcanon.dev`)
Who it's for	Solo dev on your machine	Your team, across repos
Where the graph lives	`~/.arcanon/` on your machine	Cloud storage, scoped to your org
How you view it	Local graph viewer at `http://localhost:37888`	Team dashboard in the browser
Cross-repo drift / impact	Not in the local viewer	Yes, across everything the org has scanned
Sharing	Export PNG / JSON	Live dashboard, invite teammates
Needs an account?	No	Yes (free)

/arcanon:map gets you running fully locally — no account, nothing leaves the machine. When you want to share, /arcanon:sync uploads to Hub and teammates see the same graph.

Quick Start

Install the Arcanon Claude Code plugin:

claude plugin marketplace add https://github.com/Arcanon-hub/arcanon
claude plugin install arcanon@arcanon --scope user

Then, from any repo root, run:

/arcanon:map

This builds a local service graph on your machine. Nothing leaves the box until you explicitly sync.

First-Run Flow

Install the plugin (above). The next session displays Arcanon active. and the full command list.
Log in to Arcanon Hub — get your API key from Settings → API Keys and run /arcanon:login arc_your_key_here.
Scan — run /arcanon:map in any repo to build the local graph.
Sync — run /arcanon:sync to push results to Hub (or enable auto-sync in arcanon.config.json).
View — open the dashboard at app.arcanon.dev.

How It Works

Scan locally — The plugin analyses your code on your machine via Claude Code agents. Nothing leaves until you push.
Upload results — /arcanon:sync pushes scan results to Arcanon Hub over HTTPS.
See the graph — Open the dashboard. Your entire service graph is live.
