I Built a Pay-Per-Use MCP Server with 52+ Services

Every MCP server I found was either free (good luck scaling), subscription-based (hello, vendor lock-in), or required yet another API key.

I wanted something different: a pay-per-use MCP server where you pay exactly what you use — $0.01 to $0.05 per request — via USDC micropayments on the Base blockchain.

The Stack

The x402 MCP Server wraps 52+ services behind a single HTTP endpoint:

AI Services: Web search, code analysis, text generation, translation, sentiment analysis
Web Tools: Scraping, RSS, PDF extraction, URL fetching
Halal Screening: Crypto Sharia compliance checks
Financial Data: OHLCV, crypto prices, gold/silver
URL-to-MCP Bridge: Convert any webpage into MCP-compatible tools
Marketing as a Service: Full campaign generation

Why Micropayments?

Subscription models are broken. You pay $20/month and use 2% of the quota. x402 uses the HTTP 402 Payment Required pattern — you pay per call. No commitments, no overages.
