Dated formula history, confirmed changes and evidence for U.S. pre-workout supplements.
Nobody here has read this server's code, because it publishes none. The description above is the maker's own, from the registry. A connection test shows whether it answers and what tools it says it has; it never calls a tool, so it cannot show what one does with your data.
Where it sits in the directory's order
What can be seen from outside, weighed as the directory publishes.
Observable signals: 60 of 100 points (at most 60 here)
| Input | Points | What was seen |
|---|---|---|
| Source published | held at 0 | No entry here publishes source: that is what puts it in this directory. |
| Licence stated | held at 0 | With no files, there is nothing for a licence to be stated in or held against. |
| Advisory state | held at 0 | Advisory databases index packages, and these entries publish none, so there is nothing to look up. |
| Auth declared | 15 of 15 | The registry entry declares a key or a token. |
| Latest connection test reached it | 20 of 20 | The latest test had its handshake answered. |

The tools it lists (18, as of 3 days ago)
The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.
record.searchAnswer one specific, bounded question from FormulaSignal's covered pre-workout Record. When to use: Use for a single natural-language question about a covered product: what it declares now, whether it changed, what it costs per serving, or which covered products meet one stated numeric condition. What it cannot provide: It cannot list the database, export products, answer medical or suitability questions, or answer about a product FormulaSignal does not cover. Limits: One question, at most 300 characters. Your plan has a daily limit on how many distinct products, Signals and ingredients you
products.resolveResolve a brand, product name, or alias to one canonical covered product. When to use: Call this first whenever you hold a user-supplied product name and need the canonical product_id every other capability takes. What it cannot provide: It never guesses. An ambiguous or generic name returns the candidate list and no match, and an uncovered product returns no match at all. Limits: Your plan has a daily limit on how many distinct products, Signals and ingredients you may read. Repeating a question about the same product costs nothing extra; reading many different products costs one each. Do
products.getReturn the controlled current Record for one covered product: identity, serving configuration, declared ingredients, captured price context, and freshness. When to use: Use when you need what a product declares right now, with the dates and limitations attached. What it cannot provide: It returns no preserved source bytes, no internal capture identifiers, no review notes, and no verdict about whether the product is good or suitable. Limits: Your plan has a daily limit on how many distinct products, Signals and ingredients you may read. Repeating a question about the same product costs nothi
products.historyReturn the controlled historical timeline for one covered product, with each state classified by what it can actually support. When to use: Use to find out whether a product has changed, how deep the recoverable history is, and which states are comparable to each other. What it cannot provide: It never presents an observation window as an exact reformulation date, and it never reports an unreviewed candidate as a confirmed change. Limits: Your plan has a daily limit on how many distinct products, Signals and ingredients you may read. Repeating a question about the same product costs nothing
How this entry becomes a listing
For the maker. The catalogue lists what it can read, and this server publishes nothing to read yet. There are two routes, and only the first is open today.
Publish the source Open today
- Put the server's source in a public repository on github.com, with a licence.
- Keep a server.json in that repository naming this server,
com.formulasignal/record, and declare the repository in it:"repository": { "url": "https://github.com/owner/repo", "source": "github" }, adding"subfolder"when the server lives in a folder. - Publish that version to the official MCP registry.
- The nightly registry sweep records the declaration. This page stays, dated, and says the source is declared but not yet read.
- The catalogue reads declared repositories at a pinned commit, in batches run by hand, and lists the servers that meet the batch's rules (among them a server.json at that commit naming the server, an https endpoint and a licence). When it lists this server, this page links to the listing. There is no schedule, so no date can be promised.
