Stripe setup

1. Create a Stripe account at stripe.com
2. Create a product: "Scientific Tools MCP"
3. For each tool, create a metered price:
   • Billing: recurring, monthly
   • Metered usage: sum of usage during period
   • Price per unit: tool's per-call rate
4. Copy each price ID (price_...) to your .env

Agent integration example

import anthropic

client = anthropic.Anthropic()

# Add your MCP server
response = client.beta.messages.create(

Revenue projection

At 5 tools × 1,000 calls/day × $0.01 avg price = $50/day = $1,500/month

Scale levers:

• More tools → more call volume
• Better tools → higher per-call price
• More agent integrations → more calls automatically
