This week I shipped the world’s first MCP server for ISO 10012:2026 measurement uncertainty.

The build (~48 hours):

  • 10 MCP tools (JCGM 100:2008 + 101:2008 compliant)

  • - 6 pre-built uncertainty budgets (CMM, CD-SEM, DMM, OCD, thermocouple, balance)

  • - 44 passing tests, AST-whitelisted formula parser

Built for ISO/IEC 17025 calibration labs that spend hours in Excel on the same uncertainty math every month. The buyer is a QA manager whose audit is in six months, not an AI engineer.

Try it (free 50 calls/month):

Building in public. More next week.
