MCP & Integrations MIT E1 · source linked

MCP server for Jev (TypeSafe System One): the three official question types — choice, score, noul — plus batch classify. Calibrated probabilities, ~0.5s, <$0.001/call.

JEV · Decision point

Jev returns a structured decision for the local program; consult the source for the exact decision policy.

Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.

MCP & Integrations Apache-2.0 E1 · source linked

On success each tool returns its typed result directly. On failure the tool call fails at the MCP protocol level (`isError: true`) with a short, safe message — no response body or stack trace is ever echoed back.

CLI & Pipelines MIT E1 · source linked

I kept watching coding agents burn context on decisions that aren't hard - triage 400 tickets, tag 600 files, route to one of six teams. jev-mode moves those verdicts to a typed-judgment model. I A/B'd it: 78% fewer tokens, 16x less work-attributable input, accuracy 96.1% vs 93.7%. Python, no deps, MIT.

Security & Guardrails MIT E2 · source reviewed

A CLI that sends text to TypeSafe Jev for PII category Nouls and a sensitivity Score, then locates spans with regex and segmentation.

JEV · Decision point

For each text chunk, asks twelve PII-category Nouls and a three-level sensitivity Score.

Judgment runs on TypeSafe servers; local code only locates spans, so this is not an offline privacy scanner.
