MCP + A2A

Pay anywhere with USDT,
through your AI agent.

Fund your account with USDT and tell your AI agent what to buy. Payment details are filled in securely on the server — you direct every purchase, and no card details are ever exposed.

Get Started API Reference

How it works

Run one command

Run npx livincard in your terminal. Pick your platform. Restart your app. That's the setup.

Your agent guides you

Say "Set up my LivinCard account" — the agent walks you through creating an account, picking a deposit network, and funding.

Ask your agent to buy

Tell your agent what to buy and paste the checkout URL. You confirm the amount, and payment is completed securely on the server — no card details exposed.

What the conversation looks like

You:

"Set up my LivinCard account"

Agent:

Your account is ready. API Key: lc_a87...
Save this key securely.

Which network for USDT deposits?
• TRON — lower fees
• EVM — Ethereum, BSC, Polygon, Arbitrum

You:

"TRON"

Agent:

Send USDT (TRC-20) to: TBMdv...65Z
Balance updates automatically. Ask me to buy something when you're ready.

You:

"Buy me a $50 Amazon gift card"

Quick Start

One command to connect LivinCard to your AI assistant:

Run in your terminal

npx livincard

It will ask which platform you use and auto-configure everything. Then restart your app and say:

"Set up my LivinCard account"

Cursor

Run npx livincard, pick 1. Cursor. It creates .cursor/mcp.json and a Cursor Rule that teaches the agent how to use LivinCard.

Restart Cursor, then say:

Set up my LivinCard account

What's my balance?

Buy me a $50 Amazon gift card

Pay for this: https://example.com/checkout

Manual setup (if you prefer)

Add to .cursor/mcp.json:

Claude Desktop

Run npx livincard, pick 2. Claude Desktop. It auto-configures claude_desktop_config.json.

Restart Claude Desktop, then say:

Set up my LivinCard account

Manual setup (if you prefer)

Add to claude_desktop_config.json:

OpenAI / ChatGPT

Run npx livincard, pick 4. OpenAI / ChatGPT. It prints a ready-to-paste code snippet.

Agents SDK (Python)

ChatGPT Workspace: Go to Admin → Apps → Add MCP Server and paste:

Gemini CLI

Run npx livincard, pick 3. Gemini CLI. It auto-configures ~/.gemini/settings.json.

Restart Gemini CLI, then say:

Set up my LivinCard account

Manual setup (if you prefer)

Add to ~/.gemini/settings.json:

A2A Discovery

LivinCard also supports the Agent-to-Agent (A2A) protocol. Any A2A-compatible agent can discover LivinCard automatically:

Authentication

Every user gets a unique API key when they call create_account. This key must be passed to every subsequent tool call. It ensures users can only access their own balance, cards, and transactions. Treat it like a password — do not share it.
