Overview

askjev by pZacca is an unofficial MCP server for Jev that gives coding agents a quick second opinion. The agent asks a plain question about material it already has; the server works out whether it is a yes/no, a scale or a choice, sends it to Jev and returns calibrated probabilities in one round trip, with no generative model in the loop.

It runs either hosted at jev.zacca.dev/mcp on Cloudflare Workers, which keeps nothing and forwards each call with the key you send in a header, or locally with npx -y askjev over stdio (Node 22+). Setup instructions cover Claude Code, Claude Desktop, Cursor and Codex; it is also listed on Smithery and has CI and eval workflows. It is not affiliated with TypeSafe.

What the decision model decides

TypeQuestionAnswers
OtherPlain question from the agent, mapped by the server to a Noul, Score or Choice—

How it works

  1. Agent calls the askjev tool with a question and material
  2. Server decides the question type
  3. Jev answers with probabilities
  4. Agent uses the answer as a second opinion

Strengths

  • Cheaper and faster than a sub-agent, per the README
  • Hosted option stores nothing
  • CI and eval workflows

Caveats

  • Unofficial
  • Automatic question-type mapping may misjudge intent
  • Needs a TypeSafe key
