SaferSkills independently audited Seo Optimizer Mcp (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
An MCP server that exposes a multi-agent SEO analysis toolkit to your own Claude client (Claude Code, Claude Desktop, Cursor, …): 12 specialist agents as prompts plus crawl/data tools (fetch_page, pagespeed, serp).
The reasoning runs on your own Claude (your subscription / login). You invoke a prompt, your Claude performs the analysis using these tools. No ANTHROPIC_API_KEY for the server, no central billing, no per-URL cost.
Ships as a single self-contained bundle (dist/index.js) — the only runtime dependencies are@modelcontextprotocol/sdk,zod, andcheerio.
Tools (deterministic, no LLM):
| Tool | Purpose |
|---|---|
fetch_page(url) | Fetch a URL → cleaned, readable HTML |
pagespeed(url, strategy) | PageSpeed/Lighthouse summary (Core Web Vitals + opportunities) |
serp(keyword, location?, numResults?) | Organic search results — SerpAPI if SerpAPI_KEY is set, else a key-less DuckDuckGo lookup |
Prompts — technical-auditor, page-speed, meta-optimizer, internal-link, semantic-content, cannibalization, competitor-gap, ai-visibility, company-intelligence, feedback-analyzer, geo, blog-writer, and `seo-full-analysis` (gathers evidence once, runs all 11 analysis lenses, then outputs a prioritized report).
Requires Node.js 18+. Pick whichever you prefer — both are one command, no clone, no file paths:
# From npm (after the package is published)
npx -y seo-optimizer-mcp
# …or straight from GitHub, no npm publish needed
npx -y github:emirhanyenici/SEO-Optimizer-MCPnpx installs the three deps on first run and caches them.claude mcp add seo-optimizer -s user -- npx -y seo-optimizer-mcp
# or: ... -- npx -y github:emirhanyenici/SEO-Optimizer-MCP-s user makes it available in all your projects (use -s local for justthe current one, or -s project to write a shared .mcp.json).
-e SerpAPI_KEY=… -e GOOGLE_PAGESPEED_API_KEY=….claude mcp list, or /mcp inside a session. The prompts appear asslash commands like /mcp__seo-optimizer__seo-full-analysis; the tools are available automatically.
Edit claude_desktop_config.json (Windows %APPDATA%\Claude\…, macOS ~/Library/Application Support/Claude/…):
{
"mcpServers": {
"seo-optimizer": {
"command": "npx",
"args": ["-y", "seo-optimizer-mcp"],
"env": { "SerpAPI_KEY": "optional", "GOOGLE_PAGESPEED_API_KEY": "optional" }
}
}
}Add to .cursor/mcp.json (or global ~/.cursor/mcp.json):
{
"mcpServers": {
"seo-optimizer": { "command": "npx", "args": ["-y", "seo-optimizer-mcp"] }
}
}| Var | Used by | Notes |
|---|---|---|
SerpAPI_KEY | serp | With it: SerpAPI (richer, location-aware). Without it: automatic DuckDuckGo fallback. |
GOOGLE_PAGESPEED_API_KEY | pagespeed | Works without a key (public quota); a key raises the rate limit. |
The server runs and every tool works with no env at all.
In your Claude client, pick a prompt — e.g. Full SEO Analysis — and pass url (required), keyword and competitorUrls (optional). Your Claude runs the analysis and returns an overall score + a prioritized action table + per-lens findings. All inference is billed to your account. For a single lens, invoke that specialist's prompt instead (e.g. page-speed); for an SEO article, invoke blog-writer.
The TypeScript source lives in the main SEO Optimizer project (it reuses that project's agent prompts and helpers). To cut a new release of this distributable:
# in the main project's mcp/ folder
npm run build # esbuild → dist/index.js (self-contained)Then publish/push the bundle:
npm publish # to npm → users get `npx -y seo-optimizer-mcp`
# and/or push dist + package.json + README to the public repo for `npx github:…`~30 seconds. Free. No account. Every finding cites a rule and a line of evidence.
