## The Hook

Jev MCP exposes TypeSafe’s cheap typed judgments — verify, screen, find, rerank, classify, decide, compare, extract, review, gate — as MCP tools your coding agent can call in-loop.

## What's Good

MIT (`@jkudish/jev-mcp`). Ten focused tools return probabilities/confidence in ~150–500 ms for sub-cent cost. Install via `npx -y @jkudish/jev-mcp` into Claude Code, Amp, Codex, Cursor. Broader than a single diff scorer: claim checks, context screening, and completion gates without spinning a frontier model on every page.

## The Catch

Vs Jev Review and typesafe-computer-use: this is a multi-tool judgment MCP, not the one-tool diff scorer and not a computer-use loop. Every call needs a TypeSafe API key — the MCP is OSS, the brain is not. Early software; judgments are typed scores, not prose root-cause essays.

## Verdict

MIT MCP wrapper for TypeSafe Jev when agents need cheap verify/screen/rerank/gate loops; budget the API key.
