58-rule SEO and GEO audits
Analyze local Markdown, HTML, and live-site content across crawl, on-page, content, links, structured data, AI-access, performance, security, and canonical checks.
jev-seo
Freemium
jev-seo is an open-source Rust command-line toolkit for auditing websites and local content for SEO and generative engine optimization. It also tracks rank changes, gates CI checks, and exposes its capabilities through a 15-tool MCP server for coding agents.
O que é jev-seo?
jev-seo is a free, open-source SEO and GEO command-line tool written in Rust. It runs as a single binary and is designed for developers, indie hackers, technical writers, and coding agents that need SEO evidence without relying on a dashboard subscription.
The toolkit audits local Markdown and HTML trees as well as live websites under 58 stable rules. Its checks cover areas including crawling, on-page content, links, structured data, AI access, performance, security, and canonicalization. Crawls honor robots.txt, and the same rule registry is used for crawling and auditing.
Beyond conventional SEO checks, jev-seo can score pages for AI answer-engine citation readiness using typed TypeSafe AI Jev primitives. It also stores rank history in a local SQLite file, supports rank-drift analysis, and can block CI when configured rules do not meet a required threshold. A 15-tool stdio MCP server exposes the same functionality to compatible coding agents.
The free path uses DuckDuckGo and local files. Jev semantic calls are controlled by a per-run budget, with the source documenting a default of $0.25; optional paid backends remain disabled unless a user supplies an explicit flag and key. The project is distributed under the MIT license.
O que jev-seo pode fazer?
Live crawling with robots.txt handling
Crawl live hosts while respecting robots.txt, using the same rule registry as the audit workflow.
AI citation-readiness scoring
Use TypeSafe AI Jev typed primitives to evaluate intent, GEO composite scores, and page quality; weak semantic results can be marked `[verify]` or dropped through confidence gates.
Rank history and drift analysis
Store ranking history in a local SQLite database and compare changes over time to identify rank drift.
CI gates and operational reports
Set minimum-pass or blocking-rule conditions for automated checks, with HTML reports, terminal output, CSV action tracking, and optional manifest data for requests and token usage.
15-tool MCP server
Run the toolkit as a stdio JSON-RPC 2.0 MCP server so supported coding-agent workflows can access the same SEO and GEO checks.
Casos de uso
“Pre-merge SEO checks for code changes”
Run an audit against a documentation or website directory in CI and require a minimum pass score before a change is accepted.
“Technical audits of live sites”
Crawl a live host to inspect page-level SEO and technical conditions while retaining robots.txt controls.
“Agent-assisted content and code work”
Connect the MCP server to a compatible coding agent so the agent can run SEO checks while editing site files, rather than relying only on a separate dashboard.
“Monitoring search-position changes”
Keep rank history in local SQLite and review drift between measurement periods when investigating changes in visibility.
“AI-search readiness review”
Evaluate whether pages provide signals useful for answer-engine citation and use confidence-aware outputs to identify results that require verification.
Perguntas frequentes
What is jev-seo?
jev-seo is a Rust CLI and MCP server for SEO and GEO auditing. It checks local content and live sites, evaluates AI citation readiness, tracks rank history, and supports CI enforcement.
Who is it intended for?
The source identifies developers, indie hackers, technical writers, and autonomous coding agents, including Claude Code, Gemini CLI, Cursor, and Antigravity workflows.
How does the free path work?
The documented free path uses DuckDuckGo and local files. The rules, crawls, reports, and rank history are described as free. Jev semantic calls use a configurable budget, with a documented default of $0.25 per run, and optional paid backends do not run without an explicit flag and key.
Can it be used in continuous integration?
Yes. jev-seo can gate CI on blocking rules or a minimum-pass threshold. The source shows an audit command using `--min-pass`, but the repository materials provided here do not define a complete CI setup for every platform.
How does it connect to coding agents?
It exposes 15 tools through a stdio JSON-RPC 2.0 MCP server. The source names Claude Code, Gemini CLI, Cursor, and Antigravity as compatible agent workflows, while the exact configuration depends on the MCP client.
