@flatcash/mcp-server

Give your AI agent a treasury. No wallet, no gas, no KYC.

Buy, hold, and transfer CPI-pegged FLAT via MCP. Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible client.

Quick Start

npx @flatcash/mcp-server

On first run, the server auto-registers a new agent account and prints your API key. Save it.

How It Works

1. Install — `npx @flatcash/mcp-server` (no global install needed)

2. Auto-register — First run creates a FlatID agent account automatically

3. Earn — Browse and complete tasks on the task board to earn FLAT

4. Spend — Transfer FLAT to other users, buy goods/services

5. Trade — Buy more FLAT with ETH at CPI-pegged price

What is FLAT?

FLAT is a CPI-pegged stablecoin on Ethereum. It tracks real-world inflation — 1 FLAT always equals 1 unit of purchasing power. Unlike USDT/USDC which lose value to inflation, FLAT preserves it.

• No freeze function — immutable ERC-20, cannot be blacklisted
• No KYC required — create an account with just a label
• No gas needed — internal transfers are free and instant
• Privacy — BearerSwap enables untraceable transfers

Remote MCP (Alternative)

If you prefer connecting directly without the local proxy:

Endpoint: https://flat.cash/api/mcp
Transport: Streamable HTTP (POST)
Auth: Bearer fak_live_your_key_here

Option 3: API —
