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.

Related MCP server: agentline-mcp

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.

Available Tools

Core Tools (41 tools, always available)

Remote MCP Tools (Gemini CLI extension only, requires settings)

Usage

Just ask your agent naturally:

Search the web for the latest AI research papers

Generate an image of a sunset over mountains

Send an SMS to +1234567890 saying "Hello from my AI agent"

Check my ATXP email inbox

Run this Python script in a sandbox

The agent uses the appropriate ATXP tool automatically.

Managing Your Account

Use the built-in tools or the ATXP CLI:

npx atxp@latest balance          # Check balance
npx atxp@latest fund             # Show funding options
npx atxp@latest transactions     # View transaction history
npx atxp@latest whoami           # Show account info

Billing

All tools are pay-per-use, billed to your ATXP account in USDC. Typical costs:

No subscriptions, no API keys to manage.
