Configure claude mcp https://nordicsemi.mcp.kapa.ai

[Francis S]

The MCP server requires authentication. To complete the setup, you'll need to:

1. Get an API key from Nordic Semiconductor / Kapa.ai
2. Reconfigure the server with the auth header:

claude mcp remove nordic-semiconductor-docs
claude mcp add --transport http -H "x-api-key: YOUR_ACTUAL_API_KEY" nordic-semiconductor-docs https://nordicsemi.mcp.kapa.ai

Hi,

You should be able to run this command without an API key:

claude mcp add --transport http nordic-semiconductor-docs https://nordicsemi.mcp.kapa.ai

At what point are you being prompted for a key? Please share your terminal output.

Best regards,

Benjamin

As Francis S  said, Claude says "needs authentication" when the URL is entered with the `https` prefix.

Worth noting that the "copy command line" option on the website does not include that https prefix.  If I simply paste the provided command as-is I get a different error:
