# DC Hub × ChatGPT — Integration Package

DC Hub ([dchub.cloud](https://dchub.cloud)) is a live data layer for the physical
infrastructure behind AI: data center facilities worldwide, power-market scores
(Data Center Power Index), live ISO grid telemetry, interconnection queues, fiber,
gas, water and disaster risk, and tracked data center M&A. It is served over MCP
at `https://dchub.cloud/mcp` (Streamable HTTP) and over a REST API.

## Connect

### ChatGPT connector (MCP)

> **This platform takes no MCP config file.** It runs MCP server-side and
> exposes a connector **URL field with no header field**, so there is nothing to
> paste a JSON block into.
>
> **Install:** open the DC Hub connector settings and paste
> `https://dchub.cloud/mcp` as the server URL. Auth blank — DC Hub answers
> keyless at free-tier depth. For a higher allowance call the `claim_free_key`
> tool once connected; it returns a `connect_url` carrying the key in the URL,
> which is the only durable state on this kind of client.
>
> Clients that *do* take a config file, each generated from canon:
> [Claude Desktop](https://dchub.cloud/install/claude-desktop) ·
> [Claude Code](https://dchub.cloud/install/claude-code) ·
> [Cursor](https://dchub.cloud/install/cursor) ·
> [Cline](https://dchub.cloud/install/cline) ·
> [VS Code](https://dchub.cloud/install/vscode) ·
> [Windsurf](https://dchub.cloud/install/windsurf) ·
> [Gemini CLI](https://dchub.cloud/install/gemini-cli) ·
> [Antigravity](https://dchub.cloud/install/antigravity)

### Custom GPT with Actions

1. ChatGPT → Create a GPT → Configure → Actions
2. Import from URL: `https://dchub.cloud/integrations/chatgpt/openapi.json`
3. Authentication: none for free-tier depth, or API Key → Custom header →
   `X-API-Key` → your key
4. Paste `instructions.txt` from this package into the GPT's instructions

### Direct REST

```bash
curl -H "X-API-Key: YOUR_DCHUB_KEY" \
     "https://dchub.cloud/api/agent/facilities?q=Equinix&country=US"
```

## Access

DC Hub answers keyless at free-tier depth. For a higher allowance, send
`X-API-Key: YOUR_DCHUB_KEY` (REST) or add the same header to your MCP client.
Claim a free key with the `claim_free_key` MCP tool or `POST /api/v1/keys/claim`;
plans are at <https://dchub.cloud/pricing>. `YOUR_DCHUB_KEY` in this package is a
placeholder, never a working key.
