## Charge for your MCP tools

Use `LaissezMCPProvider` to enforce payment when agents call your MCP tools. Set prices per tool and receive settlement via x402 to your wallet.

### 1) Install

```bash theme={null}
uv add laissez
uv sync --group examples
```

### 2) Wrap your MCP server

```python theme={null}
import random, secrets
from fastmcp import FastMCP
from eth_account import Account
from laissez.types import PaidTool
from laissez.mcp import LaissezMCPProvider

mcp = FastMCP("Dice Roller")

@mcp.tool
def roll_die() -> int:
    return random.randint(1, 6)

@mcp.tool
def multiply(a: int, b: int) -> int:
    return a * b

paid_tools = [
    PaidTool(name="roll_die", price=0.001, description="Roll a die"),
    PaidTool(name="multiply", price=0.005, description="Multiply numbers"),
]

wallet = Account.create(secrets.token_urlsafe(32))

app = LaissezMCPProvider(mcp=mcp, tools=paid_tools, wallet=wallet)
app.run()
```
