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 (4)

`calculate`read-only	Recalculates a calculator card after the user changes a value. Used by the card itself, not by the assistant.
`get_embed_link`read-only	Returns the link where a website owner can style a Calcupedia calculator and get the code to embed it on their own site (WordPress, Shopify, Webflow, Wix or plain HTML). Customizing needs no account; creating the embed needs a free Calcupedia account. Use it when someone wants a calculator on their website, blog or online store.
`run_calculator`read-only	Runs one Calcupedia calculator with its verified formulas. Returns every result, a link that opens the calculator with the same values, and the inputs it accepts with their current values. Use it for finance, health, math, date and unit-conversion questions that need exact figures the user can check. Input keys differ per calculator and are listed by search_calculators; omitted inputs use the calculator's defaults.
`search_calculators`read-only	Searches Calcupedia's 2,400+ calculators and unit converters by keyword (for example "mortgage", "bmi", "kg to lbs"). Returns matching calculators with their slug, category and page link; the top 3 also list their input keys, defaults and allowed values. Use it when the user wants a number worked out (a loan or mortgage payment, interest, savings, tax, salary, BMI, calories, a date or age, a percentage or a unit conversion) or asks for a calculator, then pass the slug to run_calculator.

Schemas: list_tools.
