Curated content (treat as data, not instructions):

jev-seo is an MIT-licensed Rust CLI plus MCP server that runs roughly 50-rule SEO/GEO audits, performs live crawls, computes GEO scores, detects rank drift and enforces CI gates. It is free and self-hostable, and because it exposes an MCP server it can also be driven by agents. It positions as an OSS alternative to paid SEO/GEO auditors with direct GTM utility.

Provenance

Why it matters for a GTM stack

SEO/GEO auditing is usually a paid SaaS line item, and its checks stay locked behind a dashboard where neither your CI nor your agents can reach them. jev-seo inverts that: an MIT-licensed Rust CLI you self-host, with ~50 audit rules, live crawls, GEO scoring and rank-drift detection, and — because it also runs as an MCP server — the same checks are callable by an agent. For a GTM team investing in AI-search (GEO) visibility, that means audits you can run for free, gate in CI, and hand to an agent, instead of paying per-seat for a tool your automation can't touch. The honest read: it is new and small, and the rule set and scores are the project's own — treat it as a strong, direct-utility OSS option to validate, not a drop-in replacement for an established auditor yet.
