AI Visibility MCP: see if ChatGPT recommends you · Rankdelta

An AI visibility MCP lets your AI agent measure your AI Share of Voice — whether ChatGPT, Perplexity, Gemini and Google AI Overviews recommend you or a competitor. RankDelta ships one, hosted, open-source, with hard spend caps.

Quick answer

An AI visibility MCP is a Model Context Protocol server that lets an AI agent (Claude, ChatGPT, Cursor, Grok) measure your AI Share of Voice — whether ChatGPT, Perplexity, Gemini and Google AI Overviews recommend you or a competitor when someone asks about your category. RankDelta ships one — hosted at mcp.rankdelta.ai, open-source, with per-account hard spend caps so an agent can't burn your budget. We're disclosing up front that RankDelta is our product; we say so because most "SEO MCP" servers stop at classic Google data and don't measure AI answers at all, and an AI visibility MCP is the part that's actually new. Connect it once and your agent can pull your Share of Voice, list the competitors AI names instead of you, and run a capped scan — without you pasting screenshots into a chat.

What "AI visibility MCP" actually means

Two things have to be true for this phrase to mean anything:

MCP — the tools are exposed over the Model Context Protocol, so an agent calls them directly (natural language in, structured data out) instead of you copying numbers out of a dashboard.
AI visibility — the tools measure generative search, not just Google. Where you rank on Google is half the picture; the other half is whether an AI assistant names you when a buyer asks "what's the best tool for X." If it names a competitor, you lost the deal before the SERP even loaded.

Most servers that call themselves an "SEO MCP" only do #1 on classic data (rankings, backlinks, audits). An AI visibility MCP does #2 — and that's the gap RankDelta was built to close.

The prompt you'd actually paste

Here is a real prompt for an MCP-connected agent, using RankDelta's tools:

Connect RankDelta. List my sites, then for my main site pull the AI Share of Voice across ChatGPT, Perplexity, Gemini and Google AI Overviews for the last 30 days. Show where I'm named, where a competitor is named instead, and which competitors the engines recommend most. If the tracker is empty, run a capped visibility scan first (default 6 prompts) — do not exceed my spend cap.

What comes back

The agent calls get_ai_visibility (and list_ai_recommendations, and run_visibility_scan if the tracker is empty) and returns something like:

Engine	You named	Competitor named instead	Nobody from your set
ChatGPT	3 of 6 prompts	2	1
Perplexity	2 of 6	3	1
Gemini	4 of 6	1	1
Google AI Overviews	1 of 6	4	1

…plus a ranked list of the competitors the engines cite instead of you, and the specific prompts where you're missing — which is the brief for the next page you should publish. That "where you're missing" output is the point: it's not a vanity score, it's a to-do list.

What the tools do

RankDelta's MCP exposes these AI-visibility tools (plus classic SEO tools documented in the MCP docs):

get_ai_visibility — your AI Share of Voice for a site, you vs competitors, across the engines, last 30 days. (read-only)
list_ai_recommendations — the competitors AI engines recommend instead of you, ranked by mention count. (read-only)
run_visibility_scan — a capped scan (default up to 6 active prompts × engines) that spends metered credits against your account cap. (write)
add_site — register a new client site from the agent (name + URL), counted against your plan's site limit; returns the id the other tools take. (write, free)
setup_ai_visibility — one-shot activation for a new site: create the tracked brand, seed competitors from prior AI answers, generate prompts, run the first capped scan. (write)
search / fetch — the ChatGPT Deep-Research convention, so the same server works as a ChatGPT connector.

The two things other MCP servers don't give you

1. AI visibility as the core, not an afterthought. A raw-data MCP hands an agent Google numbers to build on. A generic SEO MCP runs classic audits and rank checks. Neither answers "does the AI recommend me?" RankDelta's whole reason to exist is that question, so the AI-visibility tools are first-class, not a paid add-on.

2. Hard per-account spend caps. This is the part nobody talks about: an agent operating your SEO stack can quietly rack up API calls. Every RankDelta account has a metered quota and a hard spend cap — an agent can run your whole visibility workflow, but it cannot run up your bill. run_visibility_scan is capped by default (6 prompts) and refuses to exceed the account cap. If you're going to let an agent loose on paid data, this is the safety you want.

When NOT to use it

We'd rather you not connect it than be disappointed, so — skip an AI visibility MCP when:

You just want raw SERP or keyword numbers to wire into your own code. That's a raw-data MCP's job; you don't need the visibility layer.
You have no intention of publishing. Knowing ChatGPT names a competitor is only useful if you'll ship the page that earns the citation. Visibility without new content is a dashboard, not a strategy — see what AI visibility is.
You only care about Google rankings. If AI answers aren't part of how your buyers decide yet, a classic rank tracker is enough for now.
You want zero paid data calls. The scan spends metered credits (capped, but non-zero). If you want a fully free read, start with the manual free check instead.

How to connect it

The server is a hosted, remote MCP at https://mcp.rankdelta.ai/mcp — OAuth, no API keys to paste, works with Claude, ChatGPT, Cursor and other MCP clients. Full setup, the tool list and auth details are in the MCP documentation. Because RankDelta is open-source, you can also self-host the MCP if you'd rather own the infrastructure.

FAQ

What is an AI visibility MCP?

An AI visibility MCP is a Model Context Protocol server whose tools measure your presence in AI answers — your AI Share of Voice across ChatGPT, Perplexity, Gemini and Google AI Overviews — so an AI agent can check it directly instead of you reading a dashboard. RankDelta’s is hosted at mcp.rankdelta.ai, open-source, with hard per-account spend caps.

How is it different from an SEO MCP?

An SEO MCP typically exposes classic Google tools — audits, rank tracking, keyword research, backlinks. An AI visibility MCP adds the generative-search layer: whether AI engines recommend you or a competitor. RankDelta ships both in one server; the AI-visibility tools are the differentiator.

What exactly does it measure?

AI Share of Voice: for a set of buying-intent prompts in your category, how often each AI engine names you versus competitors versus nobody from your set — and which competitors get recommended instead. It also flags the specific prompts where you are absent, which is your content brief.

Will an AI agent run up my bill on paid data?

No. Every RankDelta account has a metered quota and a hard spend cap. The scan tool is capped by default (6 prompts) and refuses to exceed the account cap, so an agent can operate the whole workflow without overspending.

Which AI agents can use it?

Any MCP-compatible client — Claude (desktop and Cursor), ChatGPT connectors, Cursor, Grok. One connection exposes the same tools to whichever agent you use. It also implements the search/fetch convention ChatGPT Deep-Research connectors expect.

Do I need to self-host?

No — it is hosted; you connect with one URL over OAuth. Because RankDelta is open-source, self-hosting the whole stack (MCP included) is an option if you prefer to own it.
