Audn.ai Authentication Setup

Set up authentication to the Audn.ai API. This must be done before using any other audn skill.

Step 1 — Check if MCP server is already configured

Run this command to check:

claude mcp get audn-redteam 2>/dev/null && echo "EXISTS" || echo "NOT_FOUND"

Step 2 — Register the MCP server (if NOT_FOUND)

If the MCP server is not configured, register it now. Run this exact command:

claude mcp add --transport http audn-redteam https://mcp.audn.ai/mcp/audn-rn8sx

This adds the Audn.ai MCP server with OAuth 2.1 support. Claude Code will auto-discover the OAuth endpoints at https://mcp.audn.ai/.well-known/oauth-authorization-server/mcp/audn-rn8sx and handle Dynamic Client Registration automatically.

Step 3 — IMPORTANT: Restart Claude Code

After adding the MCP server, the user MUST restart Claude Code for it to pick up the new server. MCP servers are only loaded at startup — they cannot be hot-reloaded mid-session.

Tell the user exactly this:

The MCP server has been registered. You need to restart Claude Code to activate it.

1. Exit this session — type /exit or press Ctrl+C
2. Start Claude Code again: claude
3. Run /audn-login again to continue authentication

STOP HERE. Do not proceed to Step 4 until the user has restarted and re-invoked this skill.

Step 4 — Authenticate via OAuth

After restarting, the MCP server should now appear in the server list. Tell the user:

Run /mcp now, select audn-redteam, and click "Authenticate". A browser window will open — log in at auth.audn.ai (or sign up at https://audn.ai if you don't have an account). After approving, your tokens are stored securely in the system keychain and refresh automatically.

Wait for the user to complete authentication.

Step 5 — Verify

After the user authenticates, check the MCP server status:

claude mcp get audn-redteam

If it shows connected, authentication is complete. All 34 Audn API tools are now available as MCP tools.

If the user has trouble with OAuth, fall back to API token method (see below).

Fallback — API Token Method

If OAuth doesn't work (firewall, SSH, container), use an API token instead:

1. Tell the user to generate a token at: https://audn.ai/dashboard/settings (API Keys section)
2. Then run in this session:

export AUDN_API_TOKEN="<their-token>"

3. For persistence, add to shell profile:

echo 'export AUDN_API_TOKEN="<token>"' >> ~/.zshrc

4. Verify it works:

curl -s -H "Authorization: Bearer $AUDN_API_TOKEN" https://audn.ai/api/user/profile

Should return user profile with success: true.

Output

After successful authentication (either method), report:

## Authenticated with Audn.ai

**Method**: MCP OAuth / API Token
**Status**: Connected
