概览

AI 生成的概览

OpenFab 是一个远程 MCP 服务器，让助手为定制制造零件获取即时、非约束性的成本估算、交期和可制造性反馈。

可以做什么
查询支持的制造工艺、材料以及估算可接受的字段，并对同一零件在 2 至 8 种工艺间比较成本与交期，按总成本排序并给出最低成本与最短交期提示。为零件请求即时估算，并通过报价令牌在数量、材料、公差或表面处理变化时细化估算。按工艺和数量获取预计生产交期天数。针对零件规格获取基于规则的可制造性设计反馈。一次调用估算多零件物料清单，最多 50 行，返回逐行估算、BOM 总额和最长交期。
适用场景
适合助手在正式询价前快速评估零件或组件的制造方案，需要参考性价格、交期或早期可制造性提示时使用。也适合在 CNC、注塑、钣金、3D 打印或 PCB 制造等工艺之间比较成本与速度。
运行要求
需要远程 streamable HTTP 端点；未声明本地包或运行时。仅支持 stdio 的客户端可通过 mcp-remote 辅助工具连接。未声明认证、环境变量或请求头。
安装前请注意
估算仅供参考且不具约束力，服务不接受或履行订单。发送给服务的零件规格可能被记录用于改进服务，请避免提交机密设计。使用该服务不会建立商业关系。

安装

在 SourceWeft 中

  1. 打开 控制台中的 OpenFab，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/io.github.yyphilo%2Fopenfab/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

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.
