What it is
jev-cli is a small Python CLI and stdio MCP server for TypeSafe Jev, aimed at developers who need fast classification or judgment in application code instead of generated prose.
How it uses Jev
It sends text, JSON, files, or stdin state plus typed questions as noul, choice, or score, in one request or in batch via run, then returns machine-readable JSON or just the primary value for shell scripts.
Primitives:noulchoicescore
Technique worth stealing
Batch independent questions into one System One request with run to avoid one API call per question.
Try it
uv tool install jev-cli; export TYPESAFE_API_KEY='your-api-key'; jev noul -q 'Is this urgent?' -s 'Restore service today.' --value
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.
