- pass `tools.token_cost`: about 1,115 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`, `stability.new_links`: tool history recorded for 5 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

## Tools (4)

- `emetals_estimate_cbam`: Estimate embedded emissions (tCO2e) and EU CBAM certificate cost for steel exported to the EU. Input a production route (industry-average intensity, worldsteel 2023) or a carbon intensity such as an EPD A1–A3 value. The certificate cost is calculated only when an EU ETS price is given; no carbon price is assumed. Rough estimate: the free-allocation phase-out and carbon prices paid in the country of origin are not deducted. 估算鋼材出口歐盟的內含碳排與 CBAM 憑證成本；未提供 EU ETS 碳價時只算碳排量。
- `emetals_search_inventory`: Search steel products listed for sale on eMetals AI™ (plates, sections, bars, coils, pipes, offcuts and more): name, grade, size, quantity, price, city, and whether the item is EPD-certified green steel with its carbon intensity. Keyword and city accept English or Chinese (e.g. "angle" or 角鋼, "SUS304", "Taichung" or 台中市). A price of 0 means quote on request. Seller identity is not included; each item has a url to its page on emetals.tw, where signed-in members can request a quote. 搜尋平台上架中的鋼材現貨；價格 0 表示需詢價，供應商身分不在回傳內容中，詢價經由各品項的 emetals.tw 網址。
- `emetals_search_steel_specs`: Look up a steel grade: standard, description, typical uses, chemical composition limits (%) and mechanical properties by thickness (yield and tensile strength in MPa, elongation %). Data comes from published catalogues of Taiwanese mills (China Steel, Tung Ho Steel, Tang Eng, Yieh United and others): about 1,300 grades across JIS, ASTM, CNS, EN and SAE, each with its source. One grade can have different specs per product type (hot-rolled, plate, bar, section); each is listed separately. 查鋼種的規範、用途、化學成分與依厚度分段的機械性質；資料來自中鋼、東和、唐榮、燁聯、榮剛、中鋼鋁業、名佳利等鋼廠公開型錄，每筆標明來源。例：SS400、SPCC、A572 Gr.50、S45C。
- `emetals_search_suppliers`: Search a directory of Taiwanese metal material and processing suppliers; companies registered on eMetals AI™ are listed first. Filter by company name, material or city; material and city accept English or Chinese (e.g. "stainless" or 不鏽鋼, "Changhua" or 彰化縣). Returns company name, district, material and process categories, and a url to the company page on emetals.tw. Phone numbers, emails and full addresses are not included; contact goes through the emetals.tw page. 搜尋台灣金屬材料與加工供應商名錄（已入駐的優先）；回傳公司名、縣市區域、類別與公司頁網址，不含電話、email 與完整地址。
