Unit conversion toolbox covering 20 categories — length, mass, temperature, area, volume (incl. US cooking units), speed, time, data sizes (decimal MB vs binary MiB), data transfer rates (Mbps vs MB/s), acceleration incl. g-force, illumination (lux / foot-candle), pressure, energy, angle, frequency, power incl. three horsepower definitions, force, torque, typography (px/pt/em/rem), and fuel economy (mpg ↔ L/100km). Two tools — convert_unit and list_units — zero runtime dependencies, pure arithmetic; each result includes the formula applied.

Strict ISO 8601 parsing, IANA timezone conversion, and UTC calendar arithmetic.

Hosted tool server over MCP: invoice and bank-statement extraction with in-code arithmetic checks, ledger reconciliation in integer cents, PDF and table conversion, SQL dialect transpiling, and mainland-China reachability probes run from a China Mobile network vantage point.

Adds a calculate tool backed by a hand-written parser with no eval, batch evaluation and an exact-decimal mode for money math.

Checks an invoice ledger for duplicates keyed on code + number, arithmetic consistency, payer mismatch, date anomalies and template placeholders, and emits an anomaly list plus a workbook.

Checks an FMEA worksheet for element completeness and for the arithmetic that follows from it - severity, occurrence and detection against the resulting risk priority number - following published FMEA method standards. Reports inconsistencies; it does not judge whether the ratings themselves are appropriate.

Checks a bid evaluation scoring matrix for internal arithmetic consistency: that each factor's maximum, the scores recorded and the total agree with each other. Reports the differences it finds; it does not judge whether the evaluation itself was correct or fair.

Offline identifier checks and Chinese money/tax arithmetic. Checksum-verified identifiers (mainland ID, USCC, bank card, plate, VIN, ISBN, IMEI, IBAN, EAN/UPC) plus amount-in-words, IIT, VAT, mortgage schedules and 调休-aware workday counts.
