Experimental sandbox: custom-manufacturing quotes, lead time, DFM. Not a real supplier.
Do not connect
The assessed surface is high-risk. Remediate the findings before connecting.
Scanned 1 month ago Due for re-check
A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The OpenFab MCP server exposes 7 tools, focused primarily on general-purpose capabilities. Its published description reads: "Experimental sandbox: custom-manufacturing quotes, lead time, DFM". It communicates over Streamable HTTP using the 2025-06-18 protocol revision, and does not require authorization to connect. MCPGrade currently rates OpenFab D — the assessed surface is high-risk and should be remediated before use. Its most notable findings include "Data-exfiltration parameters" and "Data-exfiltration parameters". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check OpenFab's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add OpenFab to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

The tools this server advertises via tools/list — names, purposes, and the parameters each accepts, exactly as enumerated read-only.
List supported manufacturing processes, materials, and the fields an estimate accepts.
Get an instant cost estimate for a custom manufactured part. Returns unit price, total, lead time, and assumptions. Indicative and non-binding.
Refine a previous estimate (change quantity, material, tolerance, finish) by passing its quote_token.
Sorted worst-first. Each finding shows its severity, what it means, its OWASP MCP Top-10 mapping, and a recommended fix — the check id links to the exact methodology row that produced it.
