mcp-server-seo

Rust MCP server for SEO evidence used by Grok Build and Claude Code: on-page audit, robots/sitemap, polite crawl, PageSpeed Insights, Google Search Console, optional paid SERP.

stdio + JSON-RPC via rmcp. No Docker.

Build

cargo build --release
# target/release/mcp-server-seo

Config

Optional: ~/.config/mcp-server-seo/config.toml (see config.example.toml).

mkdir -p ~/.config/mcp-server-seo
cp config.example.toml ~/.config/mcp-server-seo/config.toml
chmod 600 ~/.config/mcp-server-seo/config.toml

Phase 1 tools work with zero keys. GSC needs a service-account JSON; PageSpeed needs a free API key; SERP needs Serper (optional).

Tools (summary)

Group	Tools
Foundation	`status`, `sites_list`, `site_resolve`
On-page	`page_audit`, `redirect_trace`, `robots_check`, `sitemap_fetch`, `sitemap_validate`, `extract_structured_data`, `schema_validate`, `link_check`
Crawl	`crawl_run`, `crawl_report`, `crawl_results`, `crawl_diff`, `sitemap_coverage`, `sitemap_build`
Performance	`pagespeed_audit`
GSC	`gsc_auth_check`, `gsc_search_analytics`, `gsc_opportunities`, `gsc_url_inspect`, `gsc_url_inspect_batch`, `gsc_list_sitemaps`, `gsc_submit_sitemap`
Keywords/SERP	`keyword_suggest`, `serp_fetch`, `rank_history`
Composites	`page_snapshot`, `page_history`, `audit_page`, `audit_site`, `verify_live`

Recommended free-first agent playbook

page_audit / schema_validate on home + 1–2 templates
Short crawl_run → read report.url_patterns (tag×geo / faceted explosion)
Fix in the app (not by inventing public copy)
verify_live after deploy (H1, OG ~1200×630, SearchAction probe, sitemap, patterns)
GSC sitemap submit only when the URL set is complete

Content publish (draft intros, FAQs) stays in the CMS/admin — this server is evidence, not a writer.

Safety

SSRF: public http(s) only; private/reserved IPv4+IPv6 blocked; redirect hops re-checked
sitemap_build: writes only under storage.data_dir (relative out_path)
GSC submit: confirm=YES-SUBMIT (sitemaps API — not URL Inspection)
Paid SERP: dry_run=true default; confirm=YES-PAY + budget ledger
Static HTML: rendered: false — use agent-browser for JS

Do not reimplement

Use sibling MCPs: google-analytics, google-adwords, cloudflare, namecheap, agent-browser.
