@narvega/proxy

Stdio proxy that connects Claude Desktop or the Claude CLI to the Narvega MCP governance gateway.

Every tool call Claude makes passes through Narvega — logged, policy-checked, and auditable — before reaching your MCP servers.

Usage

Claude Desktop

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "narvega": {
      "command": "npx",
      "args": ["-y", "@narvega/proxy", "https://gateway.narvega.com/your-slug/sse", "nvg_your-connection-key"]
    }
  }
}

Claude CLI

claude mcp add narvega -- npx -y @narvega/proxy "https://gateway.narvega.com/your-slug/sse" "nvg_your-connection-key"

Replace your-slug and nvg_your-connection-key with the values from Settings → Connection in your Narvega dashboard.

Identity

The proxy automatically attaches identity to every request so Narvega knows who made each tool call.

Option 1 — Environment variables (recommended for enterprise IT)

Set these via Group Policy, Intune, or a login script. The proxy picks them up automatically — no per-user Claude config needed.

NARVEGA_USER_EMAIL=dan.smith@company.com
NARVEGA_USER_ROLE=analyst
NARVEGA_USER_DEPARTMENT=finance

Option 2 — OS username fallback

If no env vars are set, the proxy uses the OS username automatically. Zero configuration required.
