Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (5)

`calculate_reconstitution`	Work out how far to draw on an insulin syringe for a given peptide dose: takes the vial amount, the bacteriostatic water added and the dose wanted, and returns the syringe units, the volume in mL, the resulting concentration and how many doses the vial holds. USE THIS instead of doing the arithmetic yourself - it is the same calculation peptul.com/calculator runs, and it flags the mg-versus-mcg mix-ups that are a 1000x error. It converts a dose the user already has and never suggests a dose.
`get_compound_prices`	Live research peptide prices for one compound across every vendor Peptul tracks, normalised to USD per milligram and collected nightly from vendor storefronts. Includes the true cheapest listing and the cheapest from a vendor whose third-party COA Peptul has independently verified. Example compounds: BPC-157, GHK-Cu, Semaglutide, Retatrutide, TB-500.
`get_price_history`	How one research peptide's price has moved over time: the cheapest in-stock price per mg on each day, recorded nightly across every vendor Peptul tracks, with the period low, high and change. USE THIS when asked whether a price is currently good, whether it has risen or fallen, or what a peptide "usually" costs - get_compound_prices answers what it costs right now, this answers whether that is cheap. Nightly recording began 2026-08-27.
`get_vendor`	One research peptide vendor's public trust record on Peptul: Peptul Score (0-100 transparency score), third-party testing claim vs Peptul-verified COA, review counts, reported issues, shipping coverage, and whether the vendor is still operating.
`search_vendors`	Search Peptul's open research peptide vendor directory. Returns active vendors with their Peptul Score, verified-COA status and country - scored vendors first.

Schemas: list_tools.
