m2m.monster MCP server (stdio): quote, build unsigned, verify and submit agent-to-agent payments over x402 on Solana.

Non-custodial payments between AI agents over x402 (m2m-split) on Solana Devnet. Free sandbox: quote a payment, build it unsigned for the payer to sign locally, verify it as the payee, submit it, and verify or refund with signed receipts. m2m.monster holds no agents' keys or funds and never signs or pays payment transactions.
