The MCP server is part of Pro, including the 7-day trial. Server URL:
https://mcp.marketnewsapi.com/mcpSet it up
- Run the command below in your terminal.
- Start Claude Code and run
/mcpto check that marketnewsapi is connected. - Without the header, choose Authenticate in
/mcpto sign in through your browser instead.
With an API key
claude mcp add --transport http marketnewsapi https://mcp.marketnewsapi.com/mcp \
--header "Authorization: Bearer mna-live-YOUR_KEY"With OAuth sign-in
claude mcp add --transport http marketnewsapi https://mcp.marketnewsapi.com/mcpReplace 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.
