## Tools (as reported by the server, not verified)

- `search\_calculators`: Search MFG Calcs' library of 5,000+ manufacturing calculators \(machining, molding, welding, OEE, cost estimating, energy, quality, maintenance, and more\). Returns matching calculators with their tool slug for run\_calculator. Try: \{"query":"OEE"\}
- `get\_calculator`: Get a calculator's inputs \(labels, units, defaults, min/max\) and formula before running it. requiresPositive marks a field whose documented minimum of 0 is really exclusive. Use the tool slug from search\_calculators. Try: \{"tool":"oee"\}
- `run\_calculator`: Run a manufacturing calculation. Provide inputs by field key or slugified label \(see get\_calculator\); missing inputs use the calculator's documented defaults. Returns labeled results with units, the formula, and a citation URL that should be shared with the user. Inputs are checked against their doc
- `lookup\_tariff`: Look up U.S. manufacturing import tariffs: HTS General/Special fields, informational Chapter 99 references, observed effective calculated-duty rate, eligible families' aggregate customs unit value, source shares, and named-source HHI floor with retained-board coverage. Search by keyword, family, or
- `get\_index`: Fetch a published MFG Calcs index, board, ledger, forecast, vintage, revision record, seasonal series, or HS-NAICS map. Tariff targets distinguish the tracked manufacturing panel's observed effective calculated-duty rate; origins are statistically associated with those reported Calculated Duties, no
- `get\_provenance`: Get the MFG Calcs Provenance Manifest: the verifiable record for every branded index and ledger on the site. For each one it returns a SHA-256 of the committed artifact and of every committed public-data input it was built from, plus the generator that reproduces it and the page that renders it. Use
- `search\_site`: Search everything on mfgcalcs.com beyond calculators: 64 live economic data series \(imports, prices, wages, energy\), 57 tariff families, state cost data, calculator categories, and datasets. Returns typed matches with URLs to cite. Use search\_calculators for the 5,000+ calculators themselves. Try: \{
- `get\_whats\_new`: Get the daily what-changed digest for the newest data day, in one call with links deeper: every agency series that published a new reading, every agency value restated \(derived signals that recomputed are listed separately by name\), every projection graded against its printed actual, and the day's M
- `get\_receipts`: Get the append-only archive of Ed25519-signed data receipts: every value signed for a series within the rolling window \(current + previous signing year\), revisions retained, each entry carrying its claim, claimHash, signature, and keyId. Call with no series for the catalogue plus the keyId→publicKey
- `get\_freshness`: Get the freshness contract for MFG Calcs' live data: every series with its measured publishing cadence, latest period, age in days, and an honest state \(current \| due \| stale \| unknown\). This is the number that decides 'answer from memory or call the tool' — and the cheapest way to know whether a re
- `get\_change\_events`: Get every published or revised observation in order with a cursor. Poll by offset instead of re-pulling series. Same engine as /api/events and the vintage archive.
- `get\_citation`: Get a ready-to-paste citation for an MFG Calcs dataset — including, for vintage-tracked datasets, the ?asOf= URL that returns the numbers exactly as they read on the access date, so the citation stays checkable after revisions instead of rotting. Carries a stable site identifier rather than a DOI; n
- `get\_vintages`: Get the MFG Calcs Vintage Archive: reproduce what a series said on a past date, before later revisions. Use series + asOf \(YYYY-MM-DD\) for the historical snapshot, series alone for its revision trail, or omit both for the catalogue. Multiple entries for one period indicate revision. Cite the returne
- `get\_revisions`: Get every restatement of a published figure with its old value, new value, and first-known date. Filter by series, artifact, since, or limit; omit filters for the full record and per-series revision summary. Use it to judge whether a recent print needs a revision caveat. Cite the returned url.
- `optimize\_sourcing`: Solve the cheapest legal supplier mix as a real linear program: given candidate suppliers with unit costs, tariff rates, freight and capacities, return the exact cost-minimizing allocation under a demand requirement, per-supplier capacity limits, and an optional diversification cap on any one suppli
- `ask`: Answer manufacturing questions from committed data; deterministic, no LLM. Missing subjects and product ties ask for clarification. Calculators collect required inputs, retain corrections via \`context\`, and run when complete; defaults appear only in explicit worked examples. Statistics name period,
- `brief`: Describe a SITUATION rather than a question and get every fact bearing on it, each answered and cited. \`ask\` for one figure, \`brief\` for a decision. Names what it could not establish. Try: \{"situation":"sourcing bearings from china"\}
