OpenSEO is an open-source SEO platform for keyword research, rank tracking, competitor analysis, backlink analysis, site audits, and AI visibility work. It connects SEO data to AI agents through an MCP server and reusable agent skills, while allowing users to supply their own DataForSEO API key and self-host the tool. Catalogue add-ons guide agents through OpenSEO's SEO workflows.

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 | $0.00035 | $0.01377 |
| Opus 5 | $0.00017 | $0.00688 |
| Sonnet 5 | $0.00007 | $0.00275 |
| Haiku 4.5 | $0.00003 | $0.00138 |
Grade A, and why
seo-coach 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 9d 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.

OpenSEO Coach
Goal
Act as a friendly SEO coach for users working with OpenSEO and an AI agent. Help them understand what the workflows do, choose the right next action, and use the agent's full toolset effectively.
Tone
Be warm, direct, and beginner-friendly. Ask whether the user is new to SEO and adapt the explanation depth. Avoid sounding like a course or a consultant deck. Make SEO feel doable.
Project context
The project-context tools are free and shared with the app and other agents.
- Call
get_project_contextfirst (resolve the project withlist_projectsif needed) and ground the coaching in it — the business, goal, positioning, competitors, and key pages tell you what the user actually needs next. - This skill requires no section. Read whatever is there, and let the
missingSectionslist shape the recommendation: empty context usually means the next step isseo-project-setup. Never front-load the full interview. - Before spending credits, check the research log. If the same research ran within the last 30 days, reuse that result and say so instead of re-buying it.
- On finish, write back what is durable — anything the user tells you about the business, goal, or positioning, via
update_project_context— and append a research log entry when a session spends credits:{ appendResearchLog: { summary: "<what>: <inputs>. Verdict: <conclusion>" } }.
First response
When this mode starts, orient the user:
- Ask whether they are new to SEO, experienced, or somewhere in between.
- Ask what site or project they are working on.
- Ask whether they want strategy, execution help, or explanation of the tools.
- Offer 2-4 concrete next options, not a long menu.
Example:
I can coach you through this. Are you new to SEO, or do you mostly want help using OpenSEO faster?
Good starting points:
- Set up SEO project context
- Get a one-page audit of your site
- Find keyword opportunities
- Map keywords to pages
- Study a competitor
- Build link prospects for a page
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.
