IMBA Agent Spend MCP

Prepaid agent MCP: USDT TRC-20 deposit and catalog buy (cards, eSIM, gifts) using your Ed25519 key.

Not Partner B2B. Not a ChatGPT money plugin. No withdraw, C2C as payer, convert, Stars, EVM, BTC, or Altyn. Humans may C2C to this client_id. Raising agent_tier does not unlock cash-out.

Windows / Cursor: npx.cmd used to break scoped bins. npm 0.1.4 matches SQL webhook URL rules, caps streamed MCP bodies, omits unused allowlist GETs, and keeps KYT / card JWE / HMAC tools. Prefer node mcp/scripts/run-npx-mcp.mjs @imba_wallet/agent-mcp (or run-spend-npx.mjs with gitignored operator secrets).

Remote Streamable HTTP: https://imbawallet.com/mcp/spend with headers X-IMBA-Agent-Client-Id and X-IMBA-Agent-Private-Key. The private-key header must be one line (PEM with \n escapes, or base64url). A Wallet JWT or agent access token is not accepted. IMBA does not host a shared spend wallet. register_agent is stdio-only.

Always re-fetch get_deposit_address before sending USDT. Pass ext_id on buys. Optional email on register_agent receives 3-D Secure OTP. Never SMS.
