概要

What is Mailerastro?

Mailerastro is an MCP server that lets AI agents send transactional emails, check wallet balances, and query reputation scores. Payments are made with USDC on Base via the x402 protocol. No API keys, accounts, or subscriptions are required—just a wallet address. It is designed for developers building agent-based email workflows.

How to use Mailerastro?

Connect any MCP-compatible client to the hosted server at https://mcp.mailerastro.com/mcp (Streamable HTTP) or run locally with npx mailerastro-mcp-server. Tools include mailerastro_send_email, mailerastro_send_batch, mailerastro_check_balance, and mailerastro_get_reputation. Configure the MAILERASTRO_API_URL environment variable if needed. For local use with Claude Desktop, add the server to claude_desktop_config.json.

よくある質問

1

What does Mailerastro do that email APIs don’t?

It eliminates API keys and subscriptions entirely. Payment happens per email via your crypto wallet, and an agent’s identity is its wallet address. A reputation system rewards consistent sending.

2

Do I need an API key or account to use Mailerastro?

No. Your wallet address is your identity. The server creates an account automatically on the first use. No sign‑up or API key is required.

3

What runtime or environment does Mailerastro require?

Node.js. The server can run locally (stdio) or as a remote HTTP service. Self‑hosting is supported on platforms like Railway.

4

How are payments handled?

Each email payment is deducted from your USDC wallet balance on Base via the x402 protocol. Plain text emails cost $0.001 each; HTML costs $0.005. Batch sends receive a 10% discount.

5

Where does my email data live?

Email data is handled by the MailerAstro API backend. The MCP server itself is a thin proxy; delivery history and reputation data reside on the API servers.
