• Claude Code: claude mcp add --transport http nppes-npi-registry https://nppes-npi-registry.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "nppes-npi-registry": {
      "url": "https://nppes-npi-registry.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your email address and a 6-digit code.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/nppes-npi-registry/

This server needs no credential — NPPES NPI Registry is a public data source. On first connect you log in with your email: we send a 6-digit code from [email protected]. The address is used only to send the code; we keep a one-way hash of it as your account id, so your free calls and your plan stay yours.
