Orlyn: Quit Drinking

npx add-mcp 'https://mcp.orlyn.ai/mcp'

Orlyn helps adults who want to drink less or stop. This server gives ChatGPT, Claude and other assistants nine small tools. Orlyn is not medical care, therapy or treatment, and the tools do not diagnose.

Tools

• score_alcohol_self_check
  Scores the AUDIT-C, the three question alcohol self-check, after the person agrees that their answers are sent. It returns the 0 to 12 score and whether it reaches the standard screening cutoff of the US Preventive Services Task Force, in fixed words that say it is not a diagnosis.
• estimate_drinking_cost
  Multiplies drinks per week by the price per drink and returns weekly, monthly, yearly and ten year totals.
• start_craving_exercise
  Returns one short exercise from the Orlyn app, box breathing, urge surfing or 5 4 3 2 1 grounding. If the person reports physical withdrawal symptoms it returns fixed medical safety text instead.
• get_support_resources
  Returns fixed safety text with emergency numbers, or a fixed suggestion to see a doctor for medication, detox or taper questions. Orlyn is not an emergency service.
• get_orlyn_app_link
  Says what the Orlyn iPhone app does and who it is for, and links its information page. Outside ChatGPT it also gives an orlyn.ai link that opens the app on the App Store.
• search_orlyn_guides
  Searches Orlyn's informational guides on orlyn.ai for a few keywords and returns up to five matches, each with sentences quoted from the guide, the date it was last updated and its link. A query about suicide, self-harm, severe withdrawal or medication gets fixed safety text instead of guides.
• count_standard_drinks
  Works out the pure alcohol and the calories from alcohol in a drink from its volume and strength, counts it under the US, UK, Australian, New Zealand, Canadian and WHO definitions, each with its official source, and adds weekly to ten year spending when drinks per week and the cost of one drink are given.
• plan_alcohol_free_challenge
  Lays out 31 Days Alcohol Free from a chosen start date, with the dates of the milestones, links to Orlyn's guides for them and for up to three hard moments, and the fixed safety line. If the person reports physical withdrawal symptoms it returns fixed medical safety text instead.
• count_alcohol_free_days
  Counts the whole alcohol-free days since the date of the last drink, after the person agrees that the date is sent, with the same rule as the Orlyn app's sober streak. It returns the milestones reached, the next one with its date, a guide for the milestone and, when drinks per week and what one drink cost are given, the money not spent. If the person reports physical withdrawal symptoms it returns fixed medical safety text instead.

Data handling

• Every tool works without sign in and is read only.
• The server receives only the inputs of the tool that was called. Inputs are fixed choices, numbers and dates, apart from the guide search, which receives a few keywords as free text. Search text is used only to find guides and is never stored, logged or counted.
• The date of the last drink is sent only after the person agrees, is used only for the count and is never stored, logged, counted or put into a link.
• Inputs are used to calculate the result and are not stored, apart from the anonymous counts below. The server does not log inputs, results, IP addresses or user agents, and keeps no conversation data.
• Our hosting providers keep short technical request logs for security, as described in the privacy policy.
• Per call metadata from the assistant, such as anonymous user or session ids and location hints, is dropped before any tool runs.
• To maintain the tools, Orlyn keeps only anonymous counts of how often each tool is used, broken down by the assistant, the outcome of the call and the language, exercise or topic chosen, with no identifier.
• Links to orlyn.ai carry campaign tags that name the assistant and the tool, never a person.
• Outside ChatGPT, links into the app open orlyn.ai/go/app, which names only the assistant, the tool and where the link sat, and forwards to the App Store page of the app with a campaign tag for the assistant. The redirect stores and counts nothing. In ChatGPT, links go to orlyn.ai pages only.
• The day count, the 31 day break, the standard drinks count, the craving exercise and the self-check can also show a card in assistants that display apps. The card runs inside the assistant with no network access, no storage and no tracking, and its links open only orlyn.ai. On an iPhone it shows a button, on a computer a QR code, and on Android one line with no link.
