SEO MCP: hand the whole SEO stack to your agent · Rankdelta
An SEO MCP lets your AI agent do real SEO work — site audits, rank tracking, keyword research, backlinks — over one connection. RankDelta ships a full-suite one, hosted, open-source, and it also measures AI visibility.
Quick answer
An SEO MCP is a Model Context Protocol server that lets an AI agent do SEO — run a site audit, check and track Google rankings, do keyword research, pull backlink and domain data — instead of you exporting numbers and pasting them into a chat. RankDelta ships a full-suite one (disclosed: it's our product), hosted at mcp.rankdelta.ai, open-source, with hard per-account spend caps. The reason to pick a full-suite SEO MCP over a raw-data one is the difference between an agent that fetches numbers and an agent that runs the workflow — audit → check ranks → find keywords → draft the fix — in a single conversation, on the same data your team uses in the dashboard. And because it's RankDelta, the same connection also answers the question classic SEO can't: whether ChatGPT and AI Overviews recommend you.
Raw-data MCP vs full-suite SEO MCP
This is the distinction most "SEO MCP" pages skip, and it's the one that decides whether the thing is useful to you:
| Raw-data MCP | Full-suite SEO MCP (RankDelta) | |
|---|---|---|
| What the agent gets | Numbers to build on | A workflow it can run end to end |
| Site audit | You build it | audit_page |
| Rankings | You build it | check_ranks, list_ranks, track_rank |
| Keyword research | Raw metrics | keyword_research (lookup / expand / domain) |
| Backlinks / domain | Raw metrics | backlink_summary, domain_overview |
| AI visibility | ✗ | ✓ (get_ai_visibility, list_ai_recommendations) |
| Who it's for | Developers wiring their own tools | Anyone who wants the agent to do SEO |
If you want raw SERP/keyword rows to wire into your own code, a raw-data MCP is the right lane and RankDelta isn't what you need. If you want to say "audit this and tell me what to fix," you want the suite.
The prompt you'd actually paste
Connect RankDelta. Audit
https://example.com/pricing, then check where the site ranks for its money terms and do keyword research (mode=expand) from the seed "ai seo software". List the top thin spots on the page, the keywords we already rank 4–15 for, and 10 related keywords with volume and difficulty. Draft only — don't publish. Stay within my spend cap.
What comes back
The agent calls audit_page, list_ranks / check_ranks, and keyword_research, and returns:
- Audit — title, headings, thin spots and obvious technical issues for the URL.
- Rank table — tracked keywords with their latest Google position (and a fresh SERP check if you asked for one, capped).
- Keyword ideas — a list of related terms, each with keyword, volume, difficulty and source.
That's three tools, one prompt, no exporting — and the "keywords we rank 4–15 for" cut is the striking-distance list you act on this week.
What makes this SEO MCP different
It runs the workflow, not just the query. The tools map to what an SEO actually does in a session — audit a page, check ranks, find keywords, look at backlinks, draft the fix — so the agent completes a task instead of handing you a spreadsheet.
It includes AI visibility. Every other SEO MCP measures Google. RankDelta's also measures whether AI engines recommend you — AI Share of Voice across ChatGPT, Perplexity, Gemini and AI Overviews — over the same connection. In 2026 that's not a nice-to-have; it's half the funnel.
It can't run up your bill. Per-account metered quotas and a hard spend cap mean an agent can operate the whole stack without burning through paid data. The scan and rank-check tools are capped and refuse to exceed your account limit.
It's open-source and hosted. Connect with one URL over OAuth (no API keys to paste), or self-host the whole thing if you'd rather own it. Setup and the full tool list are in the MCP docs.
When NOT to use it
- You only want raw data to build on. Use a raw-data MCP — you don't need the suite or the dashboard behind it.
- You never let an agent act. If you prefer clicking through a UI yourself, the MCP adds nothing over the dashboard.
- You want a free, zero-call read. Some tools spend metered credits (capped). For a no-cost first look, the manual free check is the place to start.
- Backlink index depth is your whole job. Our backlink data is a summary, not an exhaustive enterprise index — see the honest take in best MCP server for SEO.

FAQ
What is an SEO MCP?
An SEO MCP is a Model Context Protocol server that exposes SEO tools — audits, rank tracking, keyword research, backlinks — so an AI agent can run them directly over one connection. RankDelta’s is a full suite (it also measures AI visibility), hosted at mcp.rankdelta.ai, open-source, with hard spend caps.
How is it different from an SEO API?
An API is called by code you write. An MCP is called by an AI agent that decides which tool to use for a task in natural language. Same underlying data, an agent-native interface on top — so "audit this page and check my ranks" just works.
Does an SEO MCP replace my SEO tool?
It is the same tool, operated differently. RankDelta’s MCP exposes the same data as its dashboard, so the agent works on the numbers your team already uses — it is an interface, not a separate product.
Can the agent overspend on paid data?
No. Metered quotas plus a hard per-account spend cap; the scan and rank-check tools are capped by default and will not exceed your limit. An agent can run the whole workflow without running up your bill.
Which agents can connect?
Any MCP-compatible client — Claude (desktop and Cursor), ChatGPT connectors, Cursor, Grok. The server also implements the search/fetch convention ChatGPT Deep-Research connectors expect.
