# schema-markup-generator
Create and check JSON-LD schema markup for a page using facts you provide. It is for site owners, marketers, developers, and content teams. It generates and checks JSON-LD text only from facts you supply, never fetches a page, never edits a site, and gives no rich-result guarantee.

## What schema-markup-generator does, in the publisher's words

A human-guided MCP App for creating, reviewing, checking, and exporting schema.org JSON-LD from facts supplied by the user. It supports Organization, LocalBusiness, Product, Article, FAQPage, HowTo, Event, Service, WebSite, Person, and BreadcrumbList markup.

- open_schema_brief starts a brief and lists supported page types.
- review_schema_brief checks supplied facts and identifies required fields that are missing.
- generate_schema_markup uses an explicit approval receipt for the exact reviewed facts to create JSON-LD and reports recommended fields that were not supplied.
- check_schema_markup deterministically checks pasted JSON-LD for JSON validity, context, type, required and recommended properties, and common mistakes.
- export_schema_markup uses the approved brief to return both raw JSON and a safely escaped JSON-LD script tag.

The normal creation flow is open, review, approve, generate, then export. Checking pasted markup is available independently and does not imply eligibility for a rich result.
