# Json Ld Generator — MCP tool `findutils:json_ld_generator`

Generate JSON-LD structured data for 14 schema.org types (Article, BlogPosting, Product, Organization, LocalBusiness, Person, Event, FAQPage, HowTo, Recipe, WebSite, BreadcrumbList, JobPosting, Course) and return the JSON-LD string, a <script> tag, and the schema object. Known keys such as author, publisher, address, offers, brand, location, and worksFor are expanded into nested typed objects. JobPosting nests the address fields into jobLocation and baseSalary into a MonetaryAmount; datePosted defaults to today (UTC).
