Summary
Gives your AI agent a wallet, email address, and phone number so it can pay for tools without you managing API keys. The agent self-registers via the atxp_register tool, gets 10 IOU tokens to start, then pays per use for 41 built-in operations: web search, X/Twitter search, image/video/music generation, sending emails and SMS, making voice calls, and code execution. Everything bills to an ATXP account in USDC at rates like $0.01 per email or $0.05 per SMS. Reach for this when you want your agent to operate independently with real communication channels and access to paid services, not just read-only tools.

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.
