How to Monetize an MCP Server — Payment Links, Guardrails, and Scoped Tokens

MCP (Model Context Protocol) servers let AI agents use tools. But how do you charge for them?

Here's the stack I use across 61 MCP servers:

The Payment Flow

1. User discovers your MCP server on Smithery, Glama, or mcp.so
2. Free tier works instantly — no auth, rate-limited
3. Pro tier ($19/mo) — Stripe payment link → API key → full access
4. Unlimited ($99/mo) — enterprise-grade, no rate limits

The Infrastructure

Each MCP server ships with:

mcp-server/
├── src/            # TypeScript MCP implementation
├── smithery.yaml   # One-click deploy config
├── package.json    # npm publish ready
├── README.md       # Docs + Stripe link
├── LICENSE         # MIT
└── landing/        # GitHub Pages landing page

Guardrails That Matter

• Scoped tokens: Each payment creates a token scoped to one server
• Rate limiting: Free = 10 req/min, Pro = 100, Unlimited = 1000
• Audit trail: Every API call logged with SHA-256 hash
• Auto-expiry: Tokens expire when subscription ends

The Numbers

I've published 61 MCP servers with this exact stack. Every one has:

• GitHub repo with README, LICENSE, landing
• npm package
• Smithery deployment
• Stripe payment link
• Production-ready guardrails

Build Your Own

The AgentPay SDK handles auth, tokens, and payments. Drop it into any MCP server:

npm install @agentpayxyz/sdk

Ship your MCP server. Monetize it. Let agents pay agents.
