Schema Gen

sharozdawa/schema-gen
STDIOregistry active
Summary

Exposes 12 Schema.org JSON-LD generators through MCP tools like generate_schema, generate_product_schema, and generate_faq_schema. You get Person, Product, FAQ, Article, LocalBusiness, Event, and six other common types that map to Google Rich Results. Each tool takes structured input and returns valid JSON-LD markup ready to drop into your page head. There's also a validate_schema tool for checking existing markup. Reach for this when you need AI-assisted structured data generation without manually writing JSON-LD or context-switching to a web tool. The web app component gives you a standalone UI with live preview, but the MCP server is the faster path when working in Claude or Cursor.
