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.
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.
