# @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

```bash
npx @flatcash/mcp-server
```

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

## Claude Desktop Config

```json
{
  "mcpServers": {
    "flatcash": {
      "command": "npx",
      "args": ["@flatcash/mcp-server"],
      "env": {
        "FLATCASH_API_KEY": "fak_live_your_key_here"
      }
    }
  }
}
```

## Cursor / Windsurf Config

```json
{
  "mcpServers": {
    "flatcash": {
      "command": "npx",
      "args": ["@flatcash/mcp-server"],
      "env": {
        "FLATCASH_API_KEY": "fak_live_your_key_here"
      }
    }
  }
}
```

1. **Install** — `npx @flatcash/mcp-server` (no global install needed)
2. **Auto-register** — First run creates a FlatID agent account automatically

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
```

## Get an API Key

**Option 1: Auto-registration** — Just run the server, it registers automatically.

**Option 2: Manual** — Visit https://flat.cash/agents and create one from the dashboard.

**Option 3: API** —
```bash
curl -X POST https://flat.cash/api/agents/register \
  -H "Content-Type: application/json" \
  -d '{"label": "my-agent"}'
```
