Overview

AI-generated overview

Gives an AI assistant a prepaid ATXP account with a wallet, email, phone number, and pay-per-use tools such as search, media generation, SMS, and calls.

What you can do
ATXP runs as a local MCP server over stdio and exposes around 41 tools grouped into account, search, media, email, phone, contacts, and agents. Account tools let the agent self-register, check balance, fund the account, and view transactions; other tools cover web and X/Twitter search, image, video and music generation, sending and reading email from an @atxp.email address, SMS and voice calls, contact sync, and sub-agent management. Some additional remote tools, such as browsing, crawling, research, sandboxed code execution, and cloud file storage, are described as available only through the Gemini CLI extension and require settings.
When to use it
Worth adding when an assistant should pay for its own tools per use instead of managing separate API keys, or when it needs an agent-owned email address, phone number, or wallet. It suits tasks like web and social search, media generation, outbound SMS or calls, and sandboxed code execution.
Requirements
A local Node.js runtime to run the npm package atxp over stdio, plus an MCP client such as Claude Desktop, Cursor, Windsurf, or Gemini CLI. An ATXP account is needed: either self-register through the atxp_register tool or supply the ATXP_CONNECTION connection string from an existing account. Network access is required, and the account must be funded in USDC for paid tools.
Before you install
Tools are pay-per-use and billed in USDC to the ATXP account, with listed costs such as $0.05 per SMS, $0.10 per voice call, $1.00 to claim an email username, and $2.00 to register a phone number. Self-registration creates an Ethereum wallet and a connection string, and the ATXP_CONNECTION secret grants account access, so treat it as sensitive. The agent can send email, SMS, and voice calls, and can delete email, so review outbound and destructive actions. Requests and content are handled by…

Installation

In SourceWeft

  1. Open ATXP — Agent Payment & Wallet Infrastructure in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

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

bash
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):

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

Any MCP Client

bash
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:

bash
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.
