Why ARM?

The AI agent ecosystem deserves the same tooling quality that web developers have had for years.

Security-first

Every package is automatically scanned for dangerous patterns — command injection, file system abuse, network exfiltration. You see the grade before you install.

CLI-first

Search, install, audit, and publish — all from your terminal. ARM integrates directly with Claude Desktop, Cursor, VS Code, and any MCP client.

Open Source

ARM is fully open source. The CLI, the registry, the security scanner — everything. Audit the code yourself, contribute, or self-host.

Get Started in Seconds

ARM works with every MCP-compatible client. Install a package and it's automatically configured in Claude Desktop, Cursor, VS Code, and more.
