ATXP — Agent Payment & Wallet Infrastructure MCP Server

io.github.atxp-dev/atxp

Give AI agents a wallet, email, phone, and 41 paid tools—search, generation, SMS, calls, and more.

What is the ATXP — Agent Payment & Wallet Infrastructure MCP server?

The ATXP MCP server is an agent payment and wallet infrastructure that gives AI agents their own Ethereum wallet, email address, phone number, and instant access to 41 paid tools including web search, media generation, SMS, voice calls, and file storage. Agents can self-register and pay per use without managing API keys, with all transactions billed in USDC.

ATXP enables AI agents to independently access and pay for external services—web search, image/video/music generation, email, SMS, voice calls, code execution, and file storage—through a unified wallet system. Instead of managing API keys and subscriptions, agents self-register once and pay per use, making it ideal for autonomous agents that need to interact with the real world.

ATXP — Agent Payment & Wallet Infrastructure MCP server FAQ

What is ATXP?

ATXP is an agent payment and wallet infrastructure that gives AI agents their own wallet, email, phone number, and access to 41 paid tools (search, media generation, SMS, calls, code execution, file storage). Agents self-register and pay per use in USDC without managing API keys.

Is ATXP free?

ATXP is not free, but uses a pay-per-use model with no subscriptions. New agents receive 10 IOU tokens to start. Typical costs range from $0.001–$0.05 for searches and image generation, $0.01 for email, $0.05 for SMS, and $0.10 for voice calls.

How do I install ATXP in Claude Desktop or Cursor?

Add ATXP to your MCP client config (e.g., claude_desktop_config.json) with the command `npx atxp@latest`, or install via npm. After installation, restart your client for tools to load.

Do I need to authenticate or set up API keys?

No. Agents can self-register in one command by calling the `atxp_register` tool, which creates an account with a wallet, email, and phone number instantly. Alternatively, you can use an existing ATXP account by setting the `ATXP_CONNECTION` environment variable.

What payment methods does ATXP accept?

ATXP bills all transactions in USDC to your account. The README mentions funding options available via the `fund` tool, but specific payment methods are not detailed in the documentation.

Can I use ATXP with any MCP client?

Yes, ATXP runs as a standard MCP server over stdio and works with any MCP-compatible client, including Claude Desktop, Cursor, Windsurf, and Gemini CLI.

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.
