OpenFab

Experimental, agent-friendly custom-manufacturing sourcing sandbox.

This is NOT a real supplier and is not affiliated with any manufacturer. Quotes are indicative, synthetic, and non-binding. No orders are placed. Built by an engineer at Fictiv as an independent research experiment - not an official channel. Requests may be logged for research.

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.

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

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

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
• REST: /capabilities, /quotes, /lead-time, /dfm, /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

A research experiment 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.
