AiPayGen — 65+ AI Tools as an MCP Server

damien829/aipaygen
280 toolsauthSTDIO, HTTPregistry active
Summary

This is a pay-per-call API gateway that wraps 250+ tools into a single MCP server. You get AI operations like research, summarization, and translation across 15 models from OpenAI, Anthropic, Google, and others, plus web scrapers for Google Maps, Twitter, Instagram, and YouTube. It includes utility APIs for geocoding, WHOIS lookups, PDF extraction, and data transforms, along with agent infrastructure like persistent memory and task boards. Pricing starts at free for weather and crypto data, then $0.002 to $0.15 per call depending on the operation. You can pay with credit card through Stripe or USDC on Base, Solana, or Stellar using x402 micropayments. Reach for this when you want a Swiss Army knife of API access without managing dozens of separate integrations and API keys.
