PUBLIC BETA
sku-md/mcp
SKU.md Conformance and published-resource verification: remotely process caller-supplied documents without third-party fetching, or independently recheck exact public URLs at a recorded time.
Three caller-content duties, two published-resource duties
All caller-supplied content is sent to the sku.md service for processing. The first three tools make no outbound fetch to third-party URLs; the two online tools check only caller-specified exact public resources and bounded graphs explicitly declared by those documents.
Exact published-document checks and bounded declared-graph checks

Five public tools
5 tools · 57 resourcessku_md_validate_documentValidate caller-supplied SKU.md v1 Markdown and source-linked knowledge only; no live commerce authority or platform adoption guarantee.
sku_md_validate_document_graphValidate supplied catalog/product documents and safe Source checks. SKU.md v1 Markdown and source-linked knowledge only; no live commerce authority or platform adoption guarantee.
sku_md_compare_documentsCompare normalized v1 structures and a bounded Markdown diff. SKU.md v1 Markdown and source-linked knowledge only; no live commerce authority or platform adoption guarantee.
sku_md_validate_published_documentSafely fetch exact bytes through bounded public redirects. SKU.md v1 Markdown and source-linked knowledge only; no live commerce authority or platform adoption guarantee.
sku_md_validate_published_graphFetch only recognized bounded product links and Sources. SKU.md v1 Markdown and source-linked knowledge only; no live commerce authority or platform adoption guarantee.
Canonical HTTPS Resources
Every Resource uses a versioned https://sku.md/... URI and byte-matches its public Pages file. Tool names, descriptions, and the count below come directly from the implemented MCP contracts.
No surrounding-site scan
No homepage, robots.txt, Sitemap, llms.txt, platform-signal, or guessed-path scanning. Graph discovery accepts only same-origin links explicitly declared by validated Markdown documents.
No generation or user-state product
No content generation, search/index, account, draft storage, Prompt, transaction, or automatic publishing, and no merchant resource is modified.
Published-resource boundary
Exact public HTTPS URLs only, zero redirects, Markdown MIME, per-document and whole-graph budgets, same-origin declared links, and repeated DNS/private-target checks. Network uncertainty returns incomplete, never a pass.
Independent check, not certification
A remote result describes an exact response at its recorded time. It is not certification, adoption, ranking, or SEO/GEO/AEO evidence, and it does not show endorsement by any platform.
Protocol and compatibility
The primary path uses stateless MCP 2026-07-28 requests. A stateless 2025-11-25 compatibility path remains available while Claude products roll forward. Static tools and Resources do not advertise change notifications.
Data handling and anonymous access
The service is anonymous, read-only, and rate-limited. All caller-supplied content is sent to the service. Application logs do not record request bodies, document text, target URLs, source IPs, request headers, or credentials; operations use aggregate Cloudflare metrics. Do not submit secrets, credentials, or sensitive data you are not authorized to process.
Public service limits
Requests are limited to 640 KiB, each document to 256 KiB, and a graph to 32 resources and 1 MiB, with a 15-second request deadline. Limits are 20 requests per minute per source, 6 network-tool requests per minute, and 3 per target per minute.
