LaissezWhat is Laissez?
With Laissez, you have full control over how you and your agents buy and sell in the agentic economy. Build paid MCP servers or agents that pay for themselves. You get full Laissez visibility and control.
1) For MCP Server Developers
Transform your MCP tools into revenue-generating assets with just a few lines of code. Using LaissezMCPProvider, you can configure each tool to require payment when called by AI agents. Simply define your tools, set your prices, and Laissez then settles payments straight into your wallet. Oh, and all revenue is logged transparently to your dashboard.
# Create your MCP server
mcp = FastMCP("Dice Roller")
@mcp.tool
def roll_die() -> int:
return random.randint(1, 6)
# Define your paid tools
paid_tools = [
PaidTool(
name="roll_die",
price=0.001,
description="Roll a die"
),
]
# Receive payments with Laissez
app = LaissezMCPProvider(
mcp=mcp,
tools=paid_tools,
wallet=wallet
)2) For Agent Developers
Empower your agents to pay for premium MCP tools automatically with LaissezMCPConnector. Simply define how your agents should spend, and Laissez will give you complete visibility on their spending.
# Connect to paid MCP servers

)
# Create a paying agent
agent = Agent(

"Roll a dice twice then multiply"
