Ecosistema de Jev y cómo acceder a él

10 MCP judgment tools — verify a claim, screen content, rank, compare, extract, review a patch — for Claude Code / Desktop / Codex.

A single Go binary MCP connector — typed Jev decisions (yes/no, choice, score) with no runtime deps. Accepts a custom base URL.

curl -fsSL https://raw.githubusercontent.com/itsmostafa/typesafe-mcp/main/install.sh | sh

Skips YouTube sponsors from the captions and paints a color-coded sponsor-probability heatmap right on the seek bar. Catches ~77% of sponsor seconds at ~$0.0008/video. Endpoint is configurable.

git clone https://github.com/valentynkit/jev-skip && cd jev-skip
npm install && npm run build   # then load dist/chrome-mv3 unpacked

Detects and skips YouTube sponsor reads with Jev — three modes (transcript / smart / listen). Ships an extension and a web app; benchmarked against SponsorBlock.

git clone https://github.com/trungdq88/youtube-sponsor-detection
# chrome://extensions → Developer mode → Load unpacked → pick extension/

Strips the clutter off any page — Jev classifies each element as essential or noise and remembers per-site hide rules. Works via the Vercel AI Gateway or a TypeSafe key.

git clone https://github.com/kitze/unclutter && cd unclutter
bun install --frozen-lockfile && bun run build   # load .output/chrome-mv3 unpacked

Unofficial "Jev drives the tab" — sub-second click / type / select actions in the current page, no text generation. Works via OpenRouter or Cloudflare Workers AI.

git clone https://github.com/chy4pro/jev-for-chrome && cd jev-for-chrome
npm install && npm run build   # then load dist/ unpacked

Asks Jev "is this element an ad?" and removes it. The author calls it a fun prototype rather than a production ad blocker — a neat, honest demo of Jev on the DOM.

git clone https://github.com/realZachi/typesafe-adblock
# chrome://extensions → Developer mode → Load unpacked → paste your key

Semantic grep — filter text, JSON or CSV lines by meaning ("a user getting frustrated") with probabilities. Part of a suite (jsort / jselect / jlink). Runs on a gateway or fully local, no key.

uv tool install jev-grep   # then: jgrep "lines where the user is frustrated" logs.txt

Free SEO / GEO auditor — 53-rule audits, live crawl, GEO scores, rank-drift and CI gates in one static Rust binary. A key adds sections; without one it degrades to local-only.

cargo install jev-seo   # then: jev-seo audit docs/   ·   jev-seo crawl <url>

Per-turn model + reasoning-effort routing for the Pi coding agent — Jev grades each turn and picks fast / balanced / frontier, through the Vercel AI Gateway.

pi install npm:pi-jev-router   # needs Pi 0.85.1+, then /login vercel-ai-gateway

A local, OpenAI-compatible proxy between your coding agent and providers — Jev picks the cheapest capable model per turn, with a dashboard at 127.0.0.1:8787.

npm install --global jevonian   # then: jevonian

The official TypeScript / JS client for the typed decision API — the fastest way to build your own Jev tool. (A Python twin, typesafe-sdk-python, also exists.)

npm install @typesafe-ai/sdk

A hosted playground for Choice / Noul / Score with preset examples (routing, urgency, frustration, risk). Works in the browser with nothing to install.
