Parsley Health is a physician-led virtual and in-person medical practice founded in 2016 by Dr. Robin Berzin, MD, headquartered at 126 5th Ave, New York, NY, that delivers functional medicine as a membership-based primary and specialty care service. Members are matched with board-certified MD, DO, NP or PA clinicians who hold additional functional medicine fellowship training through Parsley and the Institute for Functional Medicine, and are supported by functional nutrition coaches, an RN care manager and a care coordinator. Care programs cover gut and digestive health, hormone balance, autoimmune and inflammatory conditions, unexplained symptoms, mental and emotional health, heart and metabolic health, longevity, perimenopause and menopause, fertility, pregnancy and postpartum, and environmental exposure. The membership bundles five medical visits, two nutrition coaching sessions, advanced diagnostic lab testing, a personalized care plan, a symptom tracking dashboard and unlimited messaging, priced at $150/month or $1,500/year with insurance and $275/month or $2,750/year self-pay. Parsley is available nationwide via telehealth with in-person care in New York City and Los Angeles, is in network with major commercial insurers including Aetna, Cigna, UnitedHealthcare, BlueCross BlueShield, Humana and Centene, and also operates a direct-to-consumer supplement store. Parsley Health is a consumer healthcare service rather than a developer platform: it publishes no developer portal, no API reference, no API keys and no OpenAPI, and its public GitHub organization contains internal engineering tooling (Docker images, GitHub Actions, lint configs, an Apollo Router fork) rather than any client SDK. It does, however, serve real agent-callable surfaces on its supplement store at store.parsleyhealth.com: a live anonymous Universal Commerce Protocol MCP endpoint exposing thirteen catalog, cart, checkout and order tools, an anonymous Shopify Storefront GraphQL endpoint, an llms.txt and agents.md written for agents, and OAuth 2.0 / OpenID Connect discovery documents. Those surfaces are provided by the Shopify commerce platform under Parsley Health's own hostname, cover retail supplement purchase only, and are governed by a published rule that agents must not complete payment without contemporaneous human approval. No clinical data is reachable by machine: there is no FHIR endpoint, no patient-access API and no appointment, lab or medical-record surface, and the member application at my.parsleyhealth.com remains an authenticated single-page app with no documented public API.
