Connect Gainium to ChatGPT
Connect Gainium to ChatGPT as an MCP connector. Use the read-only connector for screening, backtest review, and portfolio monitoring, or the custom connector for full read + write access.
TL;DR
Add Gainium to ChatGPT as a connector and authorize with a one-click sign-in (OAuth). The directory/read-only endpoint is https://mcp.gainium.io/read; the read + write endpoint is https://mcp.gainium.io/mcp.
Gainium connects to ChatGPT as a remote MCP connector, authorized with a secure one-click sign-in (OAuth) — no API key to copy.

Which endpoint should I use?#
| Read-only | Read + write | |
|---|---|---|
| URL | https://mcp.gainium.io/read | https://mcp.gainium.io/mcp |

| Best for | Screening, backtest review, portfolio monitoring | Hands-off trading and bot management |
Before you start#
- A Gainium account with 2FA enabled
- A ChatGPT plan that supports connectors / apps, with connector (developer/custom) access enabled in settings
Add the connector#
- In ChatGPT, open Settings → Connectors (you may need to enable custom/developer connectors first).
- Choose Add / New connector and enter the MCP server URL:
- Read-only:
https://mcp.gainium.io/read - Read + write:
https://mcp.gainium.io/mcp
- Read-only:
- ChatGPT opens a Gainium sign-in page. Sign in (with 2FA) and Authorize.
- The read-only endpoint grants view access only — nothing else to configure.
- The read + write endpoint lets you choose read or trading (write) access, and optionally paper-trading-only or a single-bot restriction, on the consent screen.
Once Gainium appears in the connector directory, you can also add it directly from there (read-only) instead of entering the URL.
Each connection is backed by a dedicated, scoped API key Gainium creates automatically; it will not appear in your manual API Keys list.
Manage or revoke#
Open Gainium → Settings → Connected apps to review or Revoke any authorized app at any time. Default to the read-only endpoint unless you specifically want ChatGPT to place or modify trades, and keep paper trading only enabled while testing.
ChatGPT's connector menus change over time — if the exact location differs, look for "Connectors," "Apps," or "MCP servers" in Settings. The Gainium URLs and OAuth flow above stay the same.
