Mcp Server
Wraps the mate.tools public JSON API as an MCP server with 35 utility tools covering text analysis, encoding, hashing, password generation, JSON/CSV/XML parsing, regex, DNS lookups, SSL certificate inspection, and JWT decoding. No API key required, zero dependencies, runs via npx. You get functions like count_lines (16 text metrics including reading time), case_convert (9 case styles in one call), url_metadata (scrapes OpenGraph and Twitter Card tags with SSRF protection), meta_tags_generate (emits ready-to-paste HTML with an SEO score), and random_gen (CSPRNG-backed UUID/dice/country generators). Useful when you need Claude to perform repetitive transformations, validate structured data, or pull metadata without writing one-off scripts.
