Connects to Deer Supply's Canadian pharmacy for GLP-1 weight-loss medications. Browse products, compare medications, get delivery estimates, track orders, and log weight and side effects on a treatment plan.

Example request: "Show me the price difference between Tirzepatide and Retatrutide pens and when they'd arrive in Toronto."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Deer Supply to help me. It is a free service with an MCP server at https://deer.supply/api/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

- get_product: Everything Deer Supply publishes about one product: what it is, sizes and prices, the published dosing schedule, what is in the box, lab (COA) reports, and the related FAQ answers. product_id comes from search_products (e.g. 'retatrutide').
- compare_weight_loss_medications: Side-by-side comparison of the three GLP weight-loss medications Deer Supply sells (Semaglutide, Tirzepatide, Retatrutide): mechanism, generation, the landmark trial's average weight loss, maintenance dose, today's starting price and lowest price per mg in CAD. Use this when some
- estimate_weight_loss: What the clinical trials averaged for someone at a given starting weight, per medication, at 6, 12 and 18 months, using the same curves as deer.supply/calculator. These are trial averages, not a prediction for any one person.
- quote_cart: Price a cart exactly as Deer Supply's checkout would: line prices with any sale or quantity break, an optional coupon code, shipping and the total in CAD, plus a delivery estimate when a Canadian postal code is given. variant_id values come from search_products. Nothing is reserv

- delivery_estimate: When an order placed now would ship and arrive, for a Canadian postal code, using the dates Deer quotes on its product pages (orders by noon Eastern ship that weekday; pens travel on the fastest service).
- get_help: Answers from Deer Supply's FAQ (shipping, storage, payment, using the pens, eligibility, returns) plus links to its policies. Pass the question; leave it empty for the whole FAQ.
- get_store_info: Who Deer Supply is and how buying works: what it sells, where it ships, payment methods accepted right now, shipping costs, the money-back policy, lab testing, and how to reach a person.
- get_lab_results: Third-party lab (COA) reports Deer Supply publishes per product size. Optional product_id.
- track_order: Status of a Deer Supply order, given its order number AND the email it was placed with (the same check as deer.supply/track). Returns the status, dates, items and tracking number. Never returns addresses or payment details.
- get_my_account: Requires signing in with a Deer account. A plain-language summary of the signed-in customer's Deer account: their name, orders with status and tracking, store credit and rewards, and (when health access was granted) each health profile's weigh-ins, plan and side effects. The same

- log_weight: Requires signing in with a Deer account. Record a weigh-in on one of the customer's health profiles. Confirm the number with the person first.

- report_side_effect: Requires signing in with a Deer account. Send a side effect to the customer's care team on one profile. If it sounds severe, tell the person to get medical help right away (call 911 or go to an emergency department) as well; this report is not an emergency channel.
