# Connect MarketNewsAPI to ChatGPT

ChatGPT connects through a custom connector with OAuth sign-in.

> The MCP server is part of [Pro](/pricing), including the 7-day trial. Server URL: `https://mcp.marketnewsapi.com/mcp`

## Set it up

1. In ChatGPT, open **Settings → Apps & Connectors → Advanced settings** and turn on **Developer mode**.
2. Back in **Apps & Connectors**, choose **Create**.
3. Name it **MarketNewsAPI**, set the MCP server URL to `https://mcp.marketnewsapi.com/mcp` and authentication to **OAuth**.
4. Click **Create**, sign in to MarketNewsAPI and click **Allow**.
5. In a new chat, add MarketNewsAPI from the **+** menu and ask away.

> Custom connectors depend on your ChatGPT plan and workspace settings. Menu names change often; look for “Connectors” or “Apps”.

## Try it

Ask something that needs current news, for example:

- “What's the latest news on NVDA and AAPL?”
- “Find press releases about semiconductor stocks from last week.”
- “Read the full Microsoft buyback press release and list the key numbers.”
- “Give me a briefing on what moved markets overnight.”

Or start from one of the built-in [prompts](/docs/mcp-tools#prompts), such as `morning_briefing`.

## Troubleshooting

- **401 / “couldn't connect”:** the key is wrong or revoked, or the OAuth sign-in didn't finish. Check your keys in the dashboard and reconnect.
- **403:** the key belongs to a Free account. MCP needs Pro.
- **Tools don't appear:** restart the app after editing config files, and make sure the JSON is valid.
