If you built an MCP server, you can sell it to AI agents globally. Here is how.
The opportunity
There are 8,560 MCP skills indexed on MarketNow. 675 developers install the MCP server every week. AI agents (Claude, Cursor, Cline) are actively looking for tools to install.
But most MCP server developers give their work away for free. They should not.
How to sell MCP skills
Step 1: Build your MCP server
from mcp.server import Server
server = Server("my-tool")
@server.tool()
def my_tool(query: str) -> str:
"""Does something useful"""
return result
Step 2: List it on MarketNow
Go to https://marketnow.site/submit
- Set your price: $0.99 to $9.99 (one-time, not subscription)
- You keep 80% of every sale
- MarketNow handles: security audit, payment processing, license issuance
Step 3: Get paid
Two payment methods:
Stripe (credit card) for human developers.
x402 + USDC on Base (crypto) for AI agents. This is especially useful for developers in countries where Stripe is not available (India, China, Southeast Asia, Africa, Latin America). USDC works everywhere.
Why USDC on Base?
Base is a Layer 2 on Ethereum. Transactions cost $0.01 and settle in 2 seconds.
For developers in India: no need for an international bank account. Just a crypto wallet and you receive USDC directly.
For developers in China: no need to worry about payment processing restrictions. USDC is borderless.
For developers in Africa: no PayPal, no Stripe, no bank verification. Just a wallet address.
Security: Sentinel L2
Every skill gets a Sentinel L2 security audit: 18 Semgrep rules + Docker sandbox + OSV check.
