概覽

AI 產生的概覽

OpenFab 是遠端 MCP 伺服器，讓助理為客製製造零件取得即時、非約束性的成本估算、交期與可製造性回饋。

可以做什麼
查詢支援的製造製程、材料以及估算可接受的欄位，並針對同一零件在 2 至 8 種製程間比較成本與交期，依總成本排序並附上最低成本與最短交期提示。為零件請求即時估算，並透過報價權杖在數量、材料、公差或表面處理變動時細化估算。依製程與數量取得預估生產交期天數。針對零件規格取得規則式的可製造性設計回饋。一次呼叫估算多零件物料清單，最多 50 行，回傳逐行估算、BOM 總額與最長交期。
適用情境
適合助理在正式詢價前快速評估零件或組件的製造方案，需要參考性價格、交期或早期可製造性提示時使用。也適合在 CNC、射出成型、鈑金、3D 列印或 PCB 製造等製程之間比較成本與速度。
執行需求
需要遠端 streamable HTTP 端點；未宣告本機套件或執行環境。僅支援 stdio 的用戶端可透過 mcp-remote 輔助工具連線。未宣告驗證、環境變數或標頭。
安裝前請注意
估算僅供參考且不具約束力，服務不接受或履行訂單。傳送給服務的零件規格可能被記錄用於改善服務，請避免提交機密設計。使用本服務不會建立商業關係。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 OpenFab，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/io.github.yyphilo%2Fopenfab/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

README

OpenFab — instant manufacturing cost estimates

Instant parametric cost estimates for custom manufacturing: CNC, molding, sheet metal, 3DP, PCB.

Estimates are indicative and non-binding; final pricing and manufacturability are subject to formal RFQ review. OpenFab is an independent estimation service and does not accept or fulfill orders. Requests may be logged to improve the service.

Autonomous sourcing and procurement agents welcome - structured MCP and REST endpoints are provided. Send a part spec and get an instant cost estimate.

OpenFab answers autonomous sourcing agents with indicative quotes, lead times, and DFM feedback across: CNC machining, injection molding, sheet metal, laser cutting, metal stamping, 3D printing, urethane casting, PCB fabrication.

Connect (agents)

Remote MCP (streamable HTTP): https://openfab-22100483453.us-central1.run.app/mcp/

Stdio MCP clients (Claude Desktop, etc.) - no install to maintain:

npx mcp-remote https://openfab-22100483453.us-central1.run.app/mcp/

REST:

curl -s -X POST https://openfab-22100483453.us-central1.run.app/quotes \  -H 'content-type: application/json' \  -d '{"process":"cnc_machining","quantity":50,"material":"aluminum","tolerance_mm":0.1,"bounding_box_mm":[120,80,25]}'

Returns indicative unit price, total, lead time, a quote_token, and assumptions. Non-binding.

Tools / endpoints

  • MCP tools: discover_capabilities, request_quote, refine_quote, get_lead_time, dfm_feedback, estimate_bom, compare_processes
  • REST: /capabilities, /quotes, /quotes/{token}/refine, /lead-time, /dfm, /bom, /compare, /openapi.json
  • Discovery: /.well-known/ai-catalog.json, /.well-known/agent-card.json, /.well-known/agent.json, /.well-known/mcp.json, /.well-known/did.json, /llms.txt

Why this exists

An instant cost-estimation service measuring whether autonomous AI agents are beginning to source custom manufacturing - what they source, how they discover suppliers, and what they expect of a supplier endpoint. Indicative only; no commercial relationship is created.
