NeverBounce MCP by usefulapi

Connect your NeverBounce account.

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://neverbounce.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http neverbounce https://neverbounce.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": {
    "neverbounce": {
      "url": "https://neverbounce.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 NeverBounce credentials.
