Should an agent connect itNot proven either way yet

Whether its tools do the product's job has not been judged yet.
Checked on 3 of the 7 days it takes to judge reliability.

Once connected

Parameters are untyped or undescribed in 18 of 19 tools: check arguments before calling.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

compare_prices
Price of one medicine with the free FineRx card at US pharmacy chains, near a place. Use when the person asks what a medicine costs, where it costs less, or its price near them or in a ZIP code. ``drug`` is a name as typed or a slug from…
ui_prices
Card prices for another dose, quantity or place — called by the FineRx card itself. Same answer as compare_prices, for the package and place picked inside the card. ``where`` is the place as typed in the card (a ZIP, a city or an…
find_nearby_pharmacies
Pharmacy stores within 30 miles, per chain — with the card price when a drug is given. Use when the person asks where the pharmacies are near a ZIP or near them. ``zip`` is a 5-digit US ZIP (leave it out to use the host's approximate…
ui_nearby
Pharmacies near a place for the package on screen — called by the FineRx card itself. ``where`` is the place as typed in the card (a ZIP, a city or an address): used for this one request, never stored. Not for the model.
get_transfer_steps
How to move a prescription from the pharmacy that has it to the one the person wants to use. Use when the person says their prescription is at another pharmacy, asks how to switch pharmacies, or picked a chain from the card prices and…
compare_basket
Card prices for several medicines at once: which pharmacy chain was seen pricing the whole list, and the sum there. Use when the person names two or more medicines and asks what they cost together, or which one pharmacy to use for all of…
ui_basket
The same list of medicines for another place — called by the FineRx card itself. ``slugs`` with their packages in parallel lists (an empty string or 0 = not set). ``where`` is the place as typed in the card: used for this one request…
open_price_finder
Open the FineRx search inside the card, so the person can look a medicine up themselves. Use when the person asks to open FineRx, wants to search or browse on their own, or is not sure of the name. Optional ``query`` pre-fills the search…
ui_suggest
Medicines matching what the person is typing in the FineRx search — called by the card itself. Up to eight matches with where their card prices start (dated), and foreign brands that matched. Not for the model.
get_savings_card
The free FineRx discount card: its codes, how to use it, how to keep it. Use when the person asks for the card, how to pay less at the pharmacy, or right after you quoted a card price. Optional ``drug`` (a slug from search_drugs) adds…
email_savings_card
Email the free FineRx discount card to an address the person gave you. Use ONLY after the person has given an email address AND confirmed they want the card sent there — ask for both first, then set ``consent`` to true. The message…
search_drugs
Find a medicine by name (brand, generic, misspelled or in another script) and get its slug. Not needed before compare_prices, compare_basket or get_transfer_steps: they take a name as typed. Use it when the person asks what FineRx has, or…
get_drug
Strengths, forms and pack sizes of one medicine that have a card price, and its default package. Use when you have a slug and need to know which strengths and quantities exist before quoting a price. Returns ``configs`` (strength × form…
get_dataset_info
What FineRx covers: pharmacy chains with card prices, how fresh they are, stores on the map, terms. Use when the person asks what FineRx is, how big or current the data is, or how to cite it. Returns the pharmacy chain families we hold…
get_prescription_options
Routes to filling a prescription, including having none yet. Use when the person says they have no prescription, asks how to get one, or says the brand costs too much. Optional ``drug`` is a slug from search_drugs (a name works too)…
find_us_equivalent
What a medicine from another country is in the US, and its card price here. Use when the person names a medicine that is not a US product — a brand from home (No-Spa, Nurofen, Dolo-Neurobion, 999 Ganmaoling), a name in another script…
find_us_equivalents
What several medicines from another country are in the US — the list a person brought from home. Use when the person names two or more medicines that are not US products (brands from home, names in another script) and asks what they are…
ui_equivalent
One foreign brand the person picked in the FineRx search — called by the card itself. The same answer as find_us_equivalent for exactly that brand (its ``brandSlug`` from ui_suggest): the reviewed guidance, word for word, and the US…
foreign_brands_for_drug
What a US drug is called abroad — the reverse of find_us_equivalent. Use when the person has the US name and wants the home-country one ("what is lisinopril called in Mexico?"). ``slug`` comes from search_drugs. Returns the reviewed…

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
