Single-purpose MCP server gating screen content through Jev decisions.

Content Moderation99%Runner-up: Classification & Routing

What it is

A single-tool MCP server that screens text for spam and toxicity. It returns a structured verdict with probabilities, category, severity, confidence, and a recommended action, for host agents that need a moderation gate.

How it uses Jev

Jev answers typed questions over the input text: spam and toxic probabilities, a category choice, and a severity score. The server combines these into violates_policy and an allow/review/block action, gated on confidence rather than spam_prob alone.

Primitives:choicescorenoul

Technique worth stealing

Gate auto-actions on calibrated confidence, not on a single probability threshold.

Try it

npm install && npm run build; run node dist/index.js, or doctor for diagnostics.
