aid: cerebelly name: Cerebelly description: 'Cerebelly is an organic baby and toddler food company founded by a practicing neurosurgeon with a PhD in developmental neurobiology from Stanford, making veggie-first purees, bone-broth protein purees, dairy-free smoothie pouches, Smart Bars and Clever Bars formulated around 16 brain-supporting nutrients. Its direct-to-consumer storefront at cerebelly.com runs on Shopify, and that storefront is its API surface: an anonymous Universal Commerce Protocol (UCP) MCP endpoint exposing 13 catalog, cart and checkout tools, a public Shopify Storefront GraphQL API answering unauthenticated introspection, an OpenID Connect customer-account authorization server, and a published llms.txt / agents.md pair that tells AI shopping agents how to transact. Cerebelly ships no developer program of its own — every machine-readable surface here is the Shopify commerce platform as deployed on Cerebelly''s own hosts.' image: https://cdn.shopify.com/s/files/1/0745/9091/2725/files/Cerebelly_Pantry_01_6a49ec81-265a-437a-ba3d-b5b94590be47.png?v=1759935945 url: https://raw.githubusercontent.com/api-evangelist/cerebelly/refs/heads/main/apis.yml x-type: company x-source: harvest:secondary-market specificationVersion: '0.23' created: '2026-08-09' modified: '2026-08-09' tags: - Company - Baby Food - Consumer Packaged Goods - Food and Beverage - eCommerce - Retail - Direct to Consumer - Shopify - Agentic Commerce - Universal Commerce Protocol - Nutrition maintainers: - FN: Kin Lane email: kin@apievangelist.com - FN: APIs.json email: info@apis.io x-enrichment: date: '2026-08-09' status: enriched artifacts_added: 24 pass: local-v1 x-coverage: state: covered reason: agent-commerce-surface-live detail: >- A consumer baby-food brand with no developer program still turned out to have three live, anonymously readable machine surfaces on its own host — an MCP endpoint returning 13 UCP commerce tools with full JSON Schemas, a Storefront GraphQL API answering unauthenticated introspection with 416 types, and an llms.txt/agents.md pair carrying a real agent policy.
