Claude SEO is an open-source Claude Code plugin that runs specialized agents and skills to audit websites across technical SEO, content quality, structured data, AI-search optimization, local and e-commerce SEO, and international SEO. SEO practitioners use it to produce prioritized recommendations based on primary-source guidance, with optional extensions for external data and crawling.
Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00098 | $0.04208 |
| Opus 5.5 | $0.00039 | $0.01683 |
| Sonnet 5.5 | $0.00020 | $0.00842 |
| Haiku 4.5 | $0.00010 | $0.00421 |
Grade A, and why
seo-dataforseo scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts
The opening of the file, as written. The whole thing — 416 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DataForSEO: Live SEO Data (Extension)
Live search data via the DataForSEO MCP server. Provides real-time SERP results (organic + images), keyword metrics, backlink profiles, on-page analysis, content analysis, business listings, AI visibility checking, and LLM mention tracking across 9 API modules with 79+ MCP tools.
Prerequisites
This skill requires the DataForSEO extension to be installed:
./extensions/dataforseo/install.sh
Check availability: Before using any DataForSEO tool, verify the MCP server
is connected by checking if serp_organic_live_advanced or any DataForSEO tool
is available. If tools are not available, inform the user the extension is not
installed and provide install instructions.
API Credit Awareness
DataForSEO charges per API call. Be efficient:
- Prefer bulk endpoints over multiple single calls
- Use default parameters (US, English) unless user specifies otherwise
- Cache results mentally within a session; don't re-fetch the same data
- Warn user before running expensive operations (full backlink crawls, large keyword lists)
Cost Guardrails
Before every DataForSEO MCP call, run cost estimation:
"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run dataforseo_costs.py check <endpoint> [--count N]
- If
"status": "approved"→ proceed with the API call - If
"status": "needs_approval"→ show the cost estimate to the user and ask for confirmation before proceeding - If
"status": "blocked"→ inform the user that the daily budget limit would be exceeded; do NOT proceed
After each API call completes, log the cost:
"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run dataforseo_costs.py log <endpoint> <actual_cost>
User commands for cost management:
/seo dataforseo costs today→ show today's spending breakdown/seo dataforseo costs summary→ show 7-day spending history/seo dataforseo costs config --mode threshold --threshold 0.50→ configure approval mode
Load references/cost-tiers.md for the full pricing table, budget presets, and cost reduction tips.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
