✓ Best for: AI agents paying for their own tools and services without API keys
✗ Not for: Users wanting traditional API key management or multi-chain support beyond Ethereum
What It Does
ATXP (Agent Transaction Protocol) is an MCP server that provisions AI agents with a complete identity stack: Ethereum wallet, email address, phone number, and instant access to paid tools. Agents self-register in one command and pay per use—no API keys to manage, no subscriptions to track.
💳
Agent Self-Registration
One command creates an account with 10 IOU tokens, unique @atxp.email address, Ethereum wallet, and saved connection string. No browser or human login required.
🔧
41 Core Tools
Account management, web/X search, AI media generation, full email inbox, SMS and voice calls, contacts with cloud sync, and sub-agent management.
🔗
Universal MCP Compatibility
Runs as standard MCP server over stdio. Works with Gemini CLI, Claude Desktop, Cursor, Windsurf, and any MCP-compatible client.
🔐
Self-Custody Ethereum Wallet
Agents control their own Ethereum wallet for payments. Fund the account to unlock ongoing tool usage beyond the initial 10 IOU tokens.
