Overview

This server exposes 28 distinct tools to your AI agent, covering mobile proxies, non-VoIP SMS verifications, dedicated phone numbers, and global eSIM plans. It requires a VoidMob API key for live operations, though a sandbox mode is available for testing with mock data.

Our verdict

This project carries a high risk level with a security score of 33/100. It is a community-maintained server that has not yet undergone editorial review, and it lacks verified security documentation for its OAuth and read-only implementations. Due to the high-risk score and potential for financial impact through its paid services, users should exercise caution and ideally rely on the sandbox mode for initial testing.

Supports a sandbox mode with mock data for testing
Provides 28 specific tools across six service domains
Uses only two direct dependencies to minimize supply-chain surface
Includes documentation for integration with Claude Desktop, Cursor, and Claude Code

Community-maintained project lacking official vendor verification
Security score of 33/100 indicates high risk
Authentication and read-only tool behaviors remain unreviewed
Single-contributor project with a high bus-factor risk

Setup

Claude Desktop

{
  "mcpServers": {
    "voidmob-mcp": {
      "args": [
        "-y",
        "@voidmob/mcp"
      ],
      "command": "npx"
    }
  }
}

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop. Some servers require API keys or tokens as environment variables — check the project's README and add an "env" object if needed.

No read-only mode — running this grants full read/write access.
No built-in authentication — anyone with access to this config can invoke every tool it exposes.

Frequently asked questions

›How can I test the server without an API key?

You can set the environment variable VOIDMOB_SANDBOX=1 to run the server in a sandbox mode. This provides in-memory mocks with a $500 play-money balance and resets state on every restart.

›What is the format of the API key?

API keys are 32-character secrets that must be prefixed with vmk_live_.

›How do I troubleshoot connection issues or inspect requests?

You can set the VOIDMOB_DEBUG environment variable to 1, which will log requests to the stderr output.

›Can I use the same API key across multiple MCP clients simultaneously?

Yes, but note that all connected clients share the same per-account rate limit. If you experience a RATE_LIMITED error during heavy parallel usage, you should implement a back-off and retry strategy.

›Is it possible to override the default API host?

Yes, you can use the VOIDMOB_BASE_URL environment variable to specify an alternative API host for advanced configurations.
