Jev-scored observable web research for MCP agents

Automated README summary

Automatically summarized from the README on 20 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

An MCP stdio server exposing guarded_search, guarded_fetch, and research_report for agents that research the web. It annotates or gates search results and fetched pages, and streams every decision to a local dashboard.

How it uses Jev

One Jev call per search result judges relevance, credibility, and worth-fetching; one call per fetched page judges answered, content class, and steering risk. Scores drive annotate or gate mode, are written to a JSONL ledger, and stream to the dashboard over SSE.

Primitives:choicescorenoul

Technique worth stealing

Judge every research step, not a sample, using atomic observable-signal criteria and a fail-open unscored badge instead of a misleading 0%.

Try it

Run SearXNG with JSON enabled, clone jev-client and jev-scout, npm install, then register the stdio server with Claude Code.

Model judgments from README excerpts

Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence

These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
