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.
After installing, start a new Gemini CLI session for the extension tools to load.
Add to your MCP client config (e.g. claude_desktop_config.json):
ATXP runs as a standard MCP server over stdio. Point any MCP-compatible client at the command above.
No browser, no human login needed. Just ask your agent:

No settings to configure — the agent is ready to use all tools immediately.
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:
For Gemini CLI, enter the token and account ID when prompted during extension setup.
