ATXP — Agent Payment & Wallet Infrastructure: Claude Code MCP server
Equips AI agents with an Ethereum wallet and pay-as-you-go access to external APIs without managing vendor keys.
claude mcp add atxp -e ATXP_CONNECTION=<ATXP_CONNECTION> -- npx -y atxpWhat ATXP — Agent Payment & Wallet Infrastructure 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.
What it helps with
- dispatch SMS text messages and place voice calls
- run web queries and generate media without separate API keys
- assign an agent its own email address on @atxp.email
- settle tool usage fees via an on-chain Ethereum wallet in USDC
Example prompts for the agent
- Create an ATXP account and show my available token balance
- Send an SMS to +1234567890 confirming the build has finished
- Create an image depicting a mountain ridge during sunset
