ATXP — Agent wallet, email, phone, and 100+ paid tools

ATXP — Agent Payment & Wallet Infrastructure

Give your AI agent a wallet, email, phone number, and instant access to paid MCP tools — web search, image/video/music generation, X/Twitter search, SMS, voice calls, code execution, file storage, and more.

ATXP (Agent Transaction Protocol) lets AI agents pay for their own tools and services without managing API keys. Self-register in one command, pay per use. Works with any MCP client.

Install

Gemini CLI

gemini extensions install https://github.com/atxp-dev/atxp

After installing, start a new Gemini CLI session for the extension tools to load.

Claude Desktop / Cursor / Windsurf

Add to your MCP client config (e.g. claude_desktop_config.json):

{
  "mcpServers": {
    "atxp": {
      "command": "npx",
      "args": ["-y", "atxp@latest"]
    }
  }
}

Any MCP Client

npx atxp@latest

ATXP runs as a standard MCP server over stdio. Point any MCP-compatible client at the command above.

Setup

Option 1: Agent self-registration (recommended)

No browser, no human login needed. Just ask your agent:

Register me on ATXP so I can use paid tools

The agent calls the atxp_register tool, which creates an account instantly with:

• 10 IOU tokens to start
• A unique email address
• An Ethereum wallet
• A connection string (saved automatically)

No settings to configure — the agent is ready to use all tools immediately.

Option 2: Use an existing ATXP account

If you already have an ATXP account from accounts.atxp.ai, set the ATXP_CONNECTION environment variable to your connection string, or pass it to the CLI:

ATXP_CONNECTION="https://accounts.atxp.ai?connection_token=<TOKEN>&account_id=<ACCOUNT_ID>" npx atxp@latest

For Gemini CLI, enter the token and account ID when prompted during extension setup.
