Connect MarketNewsAPI to Claude Desktop

Prefer a config file over the connector flow? Claude Desktop can run the server through the mcp-remote bridge with your API key.

Set it up

1. Install Node.js 18 or newer.
2. In Claude Desktop, open Settings → Developer → Edit Config.
3. Add the marketnewsapi entry below, with your key from the dashboard.
4. Quit and reopen Claude Desktop. The tools appear under the tools menu.

{
  "mcpServers": {
    "marketnewsapi": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.marketnewsapi.com/mcp",
        "--header",
        "Authorization:${AUTH_HEADER}"
      ],
      "env": {
        "AUTH_HEADER": "Bearer mna-live-YOUR_KEY"
      }
    }
  }
}

Replace mna-live-YOUR_KEY with a key from your dashboard. The Connect your AI page fills it in for you.

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, 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.
