Shopify Editions Spring '26 — MCP

Ask any AI agent what Shopify actually shipped in the Spring '26 Edition. 237 distinct changes (Shopify announced "150+"), each graded by source tier — 104 confirmed against primary docs, the rest tracked to Shopify's own marketing and flagged as such. Queryable in one call.

It doesn't claim every line is gospel — it tells you, per claim, exactly how much to trust it and why. That transparency is the point.

By Rick Watson / RMW Commerce. Snapshot: 2026-06-17 (Spring '26 release day) — coming_soon/preview items shift as Shopify ships them; re-run to refresh, or ask time_capsule(id) whether a forward-marker has landed.

See it run locally: node demo.js doc_teaming (or node demo.js all) — real dispatch() output, no faking.

Why trust it

Built by a multi-agent pipeline; every claim checked against Shopify's own docs (help center, dev docs, changelog, videos), adversarially red-teamed, with a public corrections log of what we got wrong and fixed. Full method → METHODOLOGY.md.

Found an error?

Corrections welcome — info@rmwcommerce.com. Every fix lands in the public corrections log (methodology → corrections_log); getting it right beats being right the first time.

Verify it yourself

npm install && npm test     # logic + HTTP + stdio, all asserted

About

This MCP is doc-teaming in production. See Doc-Teaming: Write Documents an Agent Can Check for the concept (grade every claim by source tier, corroborate across sources, quarantine marketing, red-team the contested lines), and Marketing to Agents for the broader playbook (for any site with a real API, shipping an MCP server beats an llms.txt).
