OpenFab tools (7)

write = sends, deletes, buys or posts
  • compare_processesFree

    Compare cost and lead time for one part across manufacturing processes. Provide 2-8 process names and a quantity; returns per-process estimates sorted by total cost, plus a lowest-cost / shortest-lead-time note. Indicative and non-binding.

  • dfm_feedbackFree

    Rule-based design-for-manufacturability feedback for a part specification.

  • discover_capabilitiesFree

    List supported manufacturing processes, materials, and the fields an estimate accepts.

  • estimate_bomFree

    Estimate costs for a multi-part bill of materials in one call. Each part: {process, quantity, material?, bounding_box_mm?, tolerance_mm?, finish?}. Returns per-line estimates, a BOM total, and the longest lead time. Indicative and non-binding. Max 50 lines.

  • get_lead_timeFree

    Estimated production lead time in days, by process and quantity.

  • refine_quoteFree

    Refine a previous estimate (change quantity, material, tolerance, finish) by passing its quote_token.

  • request_quoteFree

    Get an instant cost estimate for a custom manufactured part. Returns unit price, total, lead time, and assumptions. Indicative and non-binding.

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: discovercapabilities, requestquote, refinequote, getleadtime, dfmfeedback, estimatebom, compareprocesses

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.

Nothing above is checked by us. What we check is on the safety report.
