Install the alpha

Alpha v0.1.0 · macOS · Apple Silicon · Invite only

Prerequisites

• macOS 13 or later, Apple Silicon (M1 or newer) — Intel Macs are not supported in the alpha
• Claude Code installed and signed in (claude --version should succeed)

That’s it. No API key required — Sci uses the Claude Code login you already have, including Claude Pro or Max via OAuth. Storage is local SQLite, so there’s no Docker or Postgres to install either.

Install

Run the installer in your terminal:

curl -fsSL https://raw.githubusercontent.com/sovereign-cognitive-identity/sci/main/scripts/install.sh | bash

It asks for sudo twice — to trust the local CA certificate and to install the launchd services. The installer downloads the binary, trusts the CA, registers the sci MCP server with Claude Code, configures the proxy, and starts the background services.

If the installer offers to store an Anthropic API key, you can skip it (just press Enter) — your existing Claude Code login already works through the proxy. A key is only needed if you prefer key-based auth over OAuth.

Verify

Open a new terminal, then:

sci status     # should print  ok: true
sci verify     # sends a real request and proves your name didn't leak

If sci verify reports PASS, you’re live. Start Claude Code normally — Sci works in the background.
