What Meds is for

Most "what is this drug" answers on the internet are a paraphrase of a paraphrase. Meds goes to the documents themselves: the FDA-approved label (via openFDA) for what a drug is for, how it is taken, its warnings, contraindications, side effects and interactions; RxNorm for what a name actually is (brand ↔ generic, ingredients, forms); FAERS for what has been reported to FDA once the drug was on the market; the FDA recall and shortage lists; the NDC directory for the code on the bottle; ClinicalTrials.gov for studies; and MedlinePlus for plain-language health topics. Every answer links to the source it came from.

How the label lookup works

A name is normalised with RxNorm first (so "metformn" → metformin, "Lipitor" → atorvastatin), then the best current label is chosen: the product named that, from its original manufacturer, most recent version first; a single-ingredient oral product over a combination or an injection when the name is a generic; a repackager's copy only as a last resort (the approved text is the same). Section headings and table noise are stripped, and long sections are clipped with the full length reported so the agent can ask for more. OTC "Drug Facts" labels have no overdose or pregnancy section — Meds pulls the sentences from Warnings that address the topic and says that is what it did.

Interactions, honestly

There is no free, keyless interaction database any more (NLM retired its interaction API), so interactions does the one thing that can be done from primary sources: it reads both labels and reports every sentence in which one names the other — by generic, brand, or class ("NSAIDs", "CYP3A4 inhibitors", "ACE inhibitors"). A hit is quoted verbatim; no hit is reported as not listed, never as safe, with a nudge to the pharmacist.

What it is not

Meds is information, not medical advice, and it never invents a dose. FAERS counts are voluntary reports, not rates. Dietary supplements, non-U.S. brands and compounded products are outside the FDA label set and are said to be. For a possible overdose or poisoning the answer is always Poison Control (1-800-222-1222) or 911.

Tools

A drug

drug_lookup — What a drug is, from RxNorm and its current FDA label: brand ↔ generic, active ingredients, drug class, Rx or OTC, routes and dose forms, manufacturer, approval number, what it is approved for (label 'uses'), the boxed warning if any, which label sections exist, links to the DailyMed label and the MedlinePlus consumer page. Start here for any drug question; use label_section for the full text of a section. Args: name, prefer.

label_section — The full text of one section of the drug's FDA-approved label — uses, dosage, forms_and_strengths, boxed_warning, warnings, contraindications, side_effects, interactions, pregnancy, pediatric, geriatric, overdose, storage, mechanism, pharmacokinetics, clinical_studies, patient_info, ingredients, abuse_and_dependence, and OTC 'ask_doctor' / 'stop_use'. Use for "how is X taken", "who must not take X", "what does the label say about pregnancy". Args: name, section, prefer, max_chars, set_id.

side_effects — Two views of a drug's adverse effects: what the FDA label lists (adverse reactions section, and the boxed warning if any) and what has actually been reported to FDA's FAERS system in the last N years — the most-reported reactions with counts and the share of reports marked serious. FAERS is voluntary reporting: counts are signals, not rates. Use for "side effects of X", "is hair loss reported with Y". Args: name, prefer, years.

interactions — Do two drugs' FDA labels warn about each other? Searches each label's interaction, warning and contraindication sections for the other drug — by generic and brand name and by drug class (e.g. 'NSAIDs', 'CYP3A4 inhibitors') — and returns the matching label sentences. 'Not listed' means neither label mentions the other, which is NOT the same as safe: tell the user to confirm with a pharmacist. Use for "can I take X with Y". Args: drug_a, drug_b.

similar_drugs — Other drugs in the same FDA pharmacologic class (EPC) as this one — e.g. every statin, every SSRI — as generic names with how many labels each has, plus the class's mechanism-of-action term. Use for "what are the alternatives to X", "which drugs are in the same class as Y". Alternatives are not interchangeable; a prescriber chooses. Args: name, prefer, limit.

Safety lists

recalls — FDA drug recalls (enforcement reports): product, reason, lots, firm, class (I = could cause serious harm), distribution and dates, newest first. Use for "any recalls for X", "eye-drop recalls this year", "Class I drug recalls this month". Args: query, days, classification, limit.

shortages — FDA's drug shortage list: which presentations are in shortage, availability per manufacturer, reason, estimated resupply and the company contact. Use for "is X in shortage", "why can't I get Y", "when will Z be back". Args: query, status, limit.

ndc_lookup — Identify a product from its NDC: brand and generic name, strength, form, route, labeler, Rx/OTC, DEA schedule, package description, marketing category and the label link. Use for "what is NDC 0071-0155-23", "what's in this bottle". Args: ndc.

Research & health

clinical_trials — Studies on ClinicalTrials.gov by condition, intervention, status and place: title, phase, sponsor, status, enrollment, eligibility (age, sex), sites, central contact and the summary, with links. Use for "trials for X recruiting near Y", "is there a phase 3 for Z", "who is studying W". Args: condition, intervention, status, location, keywords, limit.

health_topic — Plain-language health information from MedlinePlus (U.S. National Library of Medicine): the topic summary — what it is, causes, symptoms, diagnosis, treatment — with the page link, related names and MeSH terms. Use for "what is atrial fibrillation", "what causes kidney stones", "what does an A1C test measure". Args: query, limit.

Conventions

• Read-only. Every tool reads public data or computes; nothing is written anywhere and nothing about the user is stored.
• Result envelope. ok: true with data, or ok: false with a structured error (bad_input, not_found, upstream_error). degraded lists optional sources that were unreachable.
• Rate limits. Free tier 60 tool calls/minute and 300/day per user (keyed on the user identifier supplied by the host agent, else client IP); Pro keys raise this. Over-limit calls return HTTP 429 with Retry-After. initialize and tools/list are never counted.

Meds — Privacy Policy

Effective 22 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Meds is. Meds is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf for U.S. drug and health information: FDA labels, side effects, label-based interaction checks, recalls, shortages, NDC lookup, clinical trials and MedlinePlus health topics. You interact with your assistant; the assistant sends us only the specific request needed: a drug name, an NDC, a condition or a topic.

What we receive. The arguments of each tool call, the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one), and standard server logs.

Health information is sensitive; we keep none of it. A request naming a drug or a condition could reveal something about a person's health. We do not store request arguments: they are used to fetch the answer and discarded. We do not receive your conversation with the assistant, your name, contacts, health records or credentials for any service. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting-provider access logs, which contain IP addresses and request paths but not request bodies, are retained for up to 30 days for security and abuse prevention. Nothing is used to build a profile, sold, shared, or used to train models.

Nothing personal is needed. Meds answers questions about drugs and conditions in general; it never asks who is taking a medicine, for a date of birth, a prescription number or any identifier.

Sub-processors. To answer requests we send only the drug name, code, condition or topic asked about (never anything about you) to openFDA (U.S. Food and Drug Administration), RxNorm and MedlinePlus (U.S. National Library of Medicine) and ClinicalTrials.gov (U.S. National Institutes of Health). Hosting: Vercel (United States regions).

Not a covered entity. Meds is a general-information service and does not provide care, hold medical records or act as a HIPAA covered entity or business associate.

Legal bases and your rights. For users in California, the EU/UK and elsewhere, our processing is necessary to provide the service you request through your assistant. Because we store no personal data beyond short-lived logs, requests to access, correct or delete personal data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days.

Children. Meds is a general-audience service operated by the adult using the assistant.

Changes. We will post changes here with a new effective date.

Meds — Terms of Service

Effective 22 September 2026. These terms govern use of the Meds connector ("the Service") operated by Unify Dynamics LLC ("we", "us").

1. The Service. Meds returns U.S. drug and health information from FDA, NLM and NIH sources: FDA-approved label text, RxNorm identity, FAERS adverse-event counts, recalls, shortages, NDC directory entries, ClinicalTrials.gov records and MedlinePlus health topics. It is accessed through an AI assistant or directly over MCP or HTTP.
2. Not medical advice. The Service provides general information reproduced from public sources. It is not medical advice, diagnosis or treatment, does not create a clinician–patient relationship, and is not a substitute for a physician, pharmacist or other qualified professional who knows the person. Never start, stop or change a medicine on the basis of the Service alone. In an emergency call 911; for a possible poisoning or overdose call Poison Control at 1-800-222-1222.
3. Accuracy and currency. Label text is reproduced as published on openFDA, which may lag DailyMed; FAERS reports are unverified and do not establish causation; recall and shortage lists change daily. Verify at the linked source before relying on anything.
4. Interaction checks. interactions reports what two labels say about each other. A result of "not listed" means neither label mentions the other, not that the combination is safe.
5. Acceptable use. Do not use the Service to overwhelm the underlying government services, to circumvent rate limits, or to make automated clinical decisions without professional review. Automated use within the published limits is welcome.
6. Availability. The Service is provided "as is" without warranty. We may change, limit or discontinue it at any time.
7. Data. Our Privacy Policy describes what we process. In short: nothing about you is stored.
8. Attribution. openFDA data is in the public domain (U.S. FDA; see open.fda.gov/terms); RxNorm and MedlinePlus are products of the U.S. National Library of Medicine; ClinicalTrials.gov is a service of the U.S. National Institutes of Health. Their terms apply to reuse of their content.
9. Pro keys. Optional Pro API keys are issued at our discretion, are personal to the holder and may be revoked for abuse.
10. Liability. To the fullest extent permitted by law, Unify Dynamics LLC is not liable for any loss, injury or harm arising from use of or reliance on the Service. Our total liability is limited to US $100.
11. Governing law. California law; venue in San Mateo County, California.
