Connect in Grok (consumer)

Copy the endpoint above: https://dchub.cloud/mcp.
In Grok, open Settings → Connectors / Integrations and choose the option to add a custom connector (remote MCP server).
Paste the URL. For auth, leave it blank (keyless free tier) or supply Authorization: Bearer <your-dchub-key>.
Save, then ask Grok: "Use DC Hub — which US grid has the most headroom right now?" and confirm a get_grid_scoreboard tool call fires.

Via the xAI API (Remote MCP)

The xAI API can attach remote MCP servers to a request. Point the Remote MCP tool block at the same endpoint with a Bearer header (exact field names per the current xAI docs):

{
  "type": "mcp",
  "server_url": "https://dchub.cloud/mcp",
  "authorization": "Bearer <your-dchub-key>"
}

Authentication

Optional. DC Hub accepts Authorization: Bearer <your-dchub-key> — and Bearer is what both Grok surfaces send: the consumer custom-connector auth field and the API's Remote MCP block. No key? Leave auth blank and use the keyless free tier.

Free tier — works with no key at all

The endpoint is keyless out of the box: 10 calls/day free, no signup. Need more headroom? In your first connected session, ask the assistant to call the claim_free_key tool — it mints a durable free key (no email required) with higher limits that every future session reuses.
