Is calculatorlib-mcp live?

Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.

Is calculatorlib-mcp free to use?

Yes — the hub reached it with no key and no payment.

What tools does calculatorlib-mcp have?

5 tools: convert_units, solve_math, get_calculator_schema, run_calculator, search_calculators.

Is calculatorlib-mcp safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• search_calculators open 29h ago

  Search CalculatorLib by keyword in any of its 12 languages — payroll, tax and social-insurance calculators for Asian markets (year-correct, legal editions cited where available) and about 8,000 general calculators. Returns the best matches (name, title, and a ready-to-use input schema) ranked by relevance and popularity. Call this FIRST, then call run_calculator with the chosen name. Example queries: "Vietnam personal income tax", "lương gross sang net", "mortgage monthly payment", "body mass index".

• convert_units unknown 2h ago

  Convert a value between units of one category (length, mass, temperature, area, volume, speed, data and 60 more). Names, symbols and common spellings work ("m", "ft", "lbs", "°C"). category is optional when the two units identify it; an unknown unit returns the category's unit list. Example: {"value":10,"from":"Meter","to":"Foot"}.

• get_calculator_schema unknown 2h ago

  Full input schema (field names, types, units, options) of one calculator. Optional: search_calculators already returns a compact schema per hit.

• run_calculator unknown never probed

  Run a calculator and get the result. Pass the calculator's name (from search_calculators) and its input fields in args. Returns the computed values plus a share link to the calculator page with inputs pre-filled; calculators backed by a legal edition also return edition, effective_from and sources[] (document, article/clause, URL) to cite. Missing inputs are refused (isError), never defaulted. When the calculator has a formula, the result ALSO includes formula_latex — the formula with the user's values substituted; show it to the user (rendered as LaTeX when your client supports it, otherwise inline as text). Example: {"name":"bmi_calculator","args":{"unitSystem":"metric","weight":70,"height":175}}.
