What it is
A local stdio MCP server that gives Cursor, Codex, and other MCP clients typed TypeSafe Jev judgments. The host agent still edits files and runs commands; Jev only returns Choice, Score, and Noul answers.
How it uses Jev
Nine tools route steps, select host-prepared tool calls, review patches, verify claims, screen content, rank candidates, and answer custom typed questions. Results include typed answers, token usage, and an action: auto, review, or escalate. Jev never invents arguments or executes tools.
Primitives:choicescorenoul
Technique worth stealing
Fuse step routing and prepared-call selection into one request to save an MCP round-trip and a host-model turn.
Try it
npm ci && npm run build, set TYPESAFE_API_KEY, then node dist/index.js doctor
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
