Summary
Pipes 238+ developer utilities directly into Claude through the Model Context Protocol. You get text processing (JSON formatting, Base64, markdown conversion), network tools (DNS lookup, WHOIS, SSL checks), code helpers (Dockerfile generation, regex testing, JWT decoding), and media operations (QR codes, image resizing, PDF generation) all as callable functions. The same endpoints power both the MCP interface and a public REST API at toolpipe.dev. Useful when you need Claude to generate a QR code, validate JSON structure, check DNS records, or format code without switching contexts. Free tier has no API key requirement, which makes it easy to drop into any MCP client configuration.
