      "command": "npx",
      "args": [
        "-y",
        "@vonage/vonage-mcp-server-api-bindings"
      ],
      "env": {

      }
    }

Gotchas

Claude Code stores MCP servers under an "mcpServers" object in ~/.claude.json. It also reads a project-scoped .mcp.json and supports adding servers from the command line with "claude mcp add". Each entry must declare either a "type" or a "command"; Claude Code refuses an entry that has neither. Remote servers connect natively over Streamable HTTP with OAuth.
