Schemas

Data Dictionary
  1. id — Internal content or product identifier.
  2. sku — SKU / product code when applicable.
  3. type — Content type, endpoint type, or search result type.
  4. title/name — Human-readable title or name.
  5. summary/description — Short or long description.
  6. url — Canonical public URL.
  7. source_url/canonical_url/citation_text/credit_required/source — Attribution fields. Preserve these when indexing, chunking, summarizing, or answering. Suggested citation format: Source: Sepp Leaf Products, {source_url}.
  8. uri — Stable route slug/URI.
  9. brand/category/tags — Catalog navigation and grouping fields.
  10. last_updated/uploaded_at — UNIX timestamp when present.
  11. mime_type/pdf_url — Media/document metadata when present.
  12. image_url/price/availability/product_type/material/finish/size/related_products/documents/charts/breadcrumbs — Best-effort product enrichment fields; chart/SDS/TDS/PDF data is MVP until the overhaul is complete.

MCP

MCP endpoints support page, limit, and since query params where applicable. Blog MCP routes may require API-key access depending on endpoint/config; open feed mirrors are listed above.

MCP is a public, read-only content gateway that exposes curated site data (products, guides, glossary, media) via MCP JSON-RPC tools and simple REST lists. Open/free use is encouraged with source credit. It provides AI-friendly, scoped access to specific content domains with stable schemas because AI systems need structured, selective access: Precise, predictable fields (IDs, titles, summaries, URLs, tags, citation metadata) made easy for tools to search and fetch without scraping HTML.

{"page":1,"limit":50,"count":1,"items":[{"id":"ABC123","title":"Example Product"}]}

Product detail pages include structured data for key product fields.

TOON

feed: products\nitems[1]{id,sku,title,url}:\n  ABC123,ABC123,"Example Product",https://seppleaf.com/products/abc123

TOON (Token-Oriented Object Notation) is a compact, human-readable encoding of JSON-style data for AI systems. These TOON endpoints are LLM-oriented mirrors of the JSON/feed data, with lower token overhead and explicit structure. Use JSON/JSONL/CSV/MCP as canonical machine sources, and TOON when prompt readability/token budget matters. Preserve citation metadata in TOON records. Product, update, guide, glossary, media, document, chart, and blog mirrors are available; document/chart/SDS/TDS/PDF fields are MVP until the data overhaul is complete. See also https://axi.md
