ATXP — Agent wallet, email, phone, and 100+ paid tools

What is ATXP?

ATXP (Agent Transaction Protocol) is an MCP server that gives AI agents a wallet, email, phone number, and access to paid MCP tools without managing API keys. It lets agents self-register and pay per use, and works with any MCP client.

How to use ATXP?

Install ATXP via the Gemini CLI extension or by adding it to an MCP client config (e.g., claude_desktop_config.json) with npx atxp@latest. Agents can self-register in one command by asking to register; alternatively, set an existing account via the ATXP_CONNECTION environment variable.

FAQ from ATXP

How does ATXP handle billing and API keys?

All tools are pay‑per‑use, billed in USDC to the ATXP account. There are no subscriptions, and agents never manage API keys — ATXP handles payments transparently.

What are the requirements to run ATXP?

ATXP runs as a standard MCP server over stdio. It requires Node.js and npx. For Gemini CLI, install the extension; for other clients, add the npx atxp@latest command to your MCP config.

Can I use an existing ATXP account?

Yes. Set the ATXP_CONNECTION environment variable to your connection string, or pass it directly to the CLI command. For Gemini CLI, enter the token and account ID when prompted.

What tools are available with ATXP?

Core tools (41 total) include account management, web/X search, image/video/music generation, full email, SMS/voice calls, contacts, and sub‑agents. Remote MCP tools (Gemini CLI only) add browsing, crawling, research, code execution, and file storage.

Where does my data live?

The README does not detail data residency. Account data is managed via ATXP’s accounts portal, and remote tools (e.g., file store) use cloud storage, but no further specifics are provided.
