## Quick Connect

### Option 1: Direct Remote Streamable HTTP (Recommended — Zero Install)

```bash
claude mcp add --transport http ariadne-nexus https://ariadnenexus.com/mcp
```

Or add to `.cursor/mcp.json` / `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "ariadne-nexus": {
      "url": "https://ariadnenexus.com/mcp",
      "headers": {
        "X-Nexus-API-Key": "nexus_live_..."
      }
    }
  }
}
```

### Option 2: Local Stdio Bridge (`npx` or Docker)

```json
{
  "mcpServers": {
    "ariadne-nexus": {
      "command": "npx",
      "args": ["-y", "github:dotlink-ops/ariadne-nexus-mcp"],
      "env": {
        "NEXUS_API_KEY": "nexus_live_..."
      }
    }
  }
}
```

To bind a specific vertical sub-server over stdio, pass `--vertical=cusip-bond-trace-finance`, `--vertical=ofac-sanctions-escrow`, or `--vertical=sec-forensics-whistleblower`.
