## What it does

This stdio MCP server links coding agents directly to 41 paid services. Instead of juggling vendor API keys, the assistant settles fees directly in USDC. Initial setup runs autonomously. Calling `atxp_register` provisions an Ethereum wallet, creates an `@atxp.email` inbox, and credits 10 starter IOU tokens.

The catalog includes web search, media creation, and SMS messaging. Usage is billed strictly per call. Rates range from $0.001 for searches up to $2.00 to lease a phone number. Once the starting allowance runs out, paid tool execution halts until the balance receives more funds. Account tracking is handled via `npx atxp@latest balance` or the `ATXP_CONNECTION` environment variable.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `ATXP_CONNECTION` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
