Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
Send physical mail with Solana payments — AI agents can compose, price, and send letters and postcards via cryptocurrency.
Call, text, or push the user's phone when an agent needs input mid-task — reply by voice instead of babysitting a long-running or blocked terminal. Works with any MCP client, not just Claude. Install: npx -y @paigy/mcp@latest.
