Every API key is bound to one brand and authenticates all MCP and agent requests made on that brand’s behalf. Keys are created in your ElarisLabs profile under API keys / MCP.

​
How do I create a brand-bound API key?

1

Open your profile

Go to your profile and select API keys / MCP.
2

Choose a brand

Select the brand this key will act on. All generation spend is billed to that brand’s credit balance.
3

Set expiry and spend cap

Set an expiry (max 24 weeks) and a per-key spend cap (max 2000 credits). Both are editable after creation.
4

Copy the key

Copy the key (elx_live_...). It is shown only once. Store it in a secrets manager or environment variable immediately.

Bound to a brand

The key acts on one brand. All spend is billed to that brand’s credit balance.

Expiry and spend cap

Required expiry up to 24 weeks. Per-key spend cap up to 2000 credits, editable anytime.

Revoke or rotate

Rotate to replace a key, or revoke to disable it instantly. Manage all keys from settings.

Scopes

Keys ship with studio:read and studio:generate. That is enough to list projects and run generation tools.
Endpoint: your MCP URL is https://studio.elarislabs.ai/api/mcp. Authenticate with Authorization: Bearer elx_live_.... The server uses Streamable HTTP (stateless). It works with Claude Desktop, Cursor, and mcp-remote for older clients.
Security: treat elx_live_... like a password. Never commit it to git, paste it in public channels, or share it in screenshots. Prefer separate keys per client (Claude vs Cursor vs CI) with low spend caps when possible.

​
Where to next

MCP setup

Paste the key into Claude, Cursor, or another MCP client.
