Connect MarketNewsAPI to Windsurf

Give Windsurf's Cascade agent live market news.

Set it up

1. Open Windsurf Settings → Cascade → MCP servers and choose View raw config (~/.codeium/windsurf/mcp_config.json).
2. Add the entry below with your key and save.
3. Press Refresh in the MCP panel. The tools appear in Cascade.

{
  "mcpServers": {
    "marketnewsapi": {
      "serverUrl": "https://mcp.marketnewsapi.com/mcp",
      "headers": {
        "Authorization": "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.
