Best SEO MCP Servers 2026: 10 Tested, Free to $129/mo

SEO data is leaving the dashboard. For fifteen years, checking a keyword meant logging into Ahrefs or Semrush, clicking through tabs, and copying numbers into a doc. Now you can ask your AI agent the same question and get the answer in the chat you are already working in.

The thing that makes that possible is an SEO MCP server, a connector that hands Claude, Cursor, or ChatGPT live search data through the Model Context Protocol. Plug one in and your agent can pull keyword volumes, difficulty scores, rankings, and competitor data on demand.

By 2026 there are real options, from free developer tools to official servers from the big SEO names to standalone products. This is an honest comparison of the ten worth knowing, who each one is for, and where each one falls down.

Pick an SEO MCP server by the job

Product access and advertised prices were checked against official sources on August 19, 2026, and SE Ranking’s MCP access model was re-checked on August 27. This page includes ContextBolt SEO, which we make. It is first because it is the only standalone server here, rather than a feature of a suite plan, and it saves the research to its own dashboard. The suites keep their place for people who already pay for them.

If you actually wanted web search rather than SEO data, you are in the wrong category and it is an easy mix-up. Servers like Exa, Tavily and Brave return what the web says; the ones below return where you rank in it. Web Search MCP Servers compares that side, where two of the seven are free and need no API key.

How we picked these 10 SEO MCP servers

The MCP ecosystem has hundreds of servers. These criteria narrowed the field to the ones that actually do SEO work.

• It exposes real SEO data: Keyword research, rankings, SERP, domain or backlink data. Not just generic web search.
• It works in mainstream agents: Claude, Cursor, Windsurf, or ChatGPT, through standard MCP.
• It is maintained in 2026: Live, documented, and not an abandoned side project.
• It serves a distinct buyer: No two entries here are the right call for the same person.

If you are new to the whole idea, start with the plain-English version first, then come back to compare the options.

The 10 best SEO MCP servers at a glance

1. ContextBolt SEO: a standalone SEO MCP server at $35 a month

Best for: founders, marketers, and indie hackers who do their own SEO and do not want a dashboard subscription.

Full disclosure, since you are reading this on the ContextBolt blog. We make this one. With that bias on the table, here is why it is first.

ContextBolt SEO is a hosted SEO MCP server. You subscribe, you get one MCP URL, and you paste it into Claude, Claude Code, Cursor, Codex, or Windsurf. There is no DataForSEO account to register and nothing to install, and every lookup saves itself to your SEO Dashboard as you go. It covers the whole surface, keyword and SERP research, domain and competitor analysis, page and site audits, backlinks (an overview, referring domains, and a competitor gap finder), AI visibility, and a read-only connection to your own Search Console with daily snapshots, all on one plan. Cross-session memory and the private SEO Dashboard run automatically alongside them.

It also audits your pages. Ask it to audit your site and it grades the on-page basics against a strict checklist, then hands back a score and a fix-list. Several servers here audit, and SEOptimer does little else. What is different is that this one runs inside the agent doing the work, so you can tell it to fix the top issues and re-check the same page in the same chat. The others hand you a report and stop there.

The pitch is two-fold. The first half is the price shape. It sits on DataForSEO so the numbers are Ahrefs-grade, but you pay $35 a month for 1,000 credits instead of a suite subscription for a dashboard you open twice a month. It is the only standalone product here. Every other paid entry is either a feature of a suite plan or an API bill you run yourself, and the two free ones only see sites you own. The second half shows up nowhere else on this list. ContextBolt SEO remembers what you have researched across sessions. Ask about the same keyword next week and the answer leads with what has changed (difficulty has gone from 47 to 52 and search volume from 4.4K to 4.9K a month, since you last looked 8 days ago), at no extra credit cost. Every lookup also lands on a private SEO Dashboard, so the research has a home rather than scrolling out of a chat. None of the other servers in this list do any of that. The ContextBolt SEO guide is a quick click-through of setup and a few real workflows.

The backlink tools cover the common questions, a domain’s authority, who links to it, and who links to your competitors but not you. Research calls draw on the 1,000 credits a month, with backlink calls costing three each; memory and the SEO Dashboard are free and do not count. It starts with a 7-day free trial, card required, with 100 credits to run it against your own site before the first charge.

Verdict: the standalone way to get keyword, SERP, domain, competitor, backlink and audit data into your agent without buying a dashboard, and the only entry here that remembers what you have researched across sessions and collects every finding on a private SEO Dashboard. If you do your own SEO, start the 7-day trial.

2. DataForSEO MCP: the raw data layer most SEO servers sit on

Best for: developers who want direct access to the raw data and will shape it themselves.

DataForSEO is a wholesaler. It sells the same class of keyword, SERP, traffic, and backlink data that quietly powers a long list of SEO products, and it now ships an official MCP server on top of that API.

The coverage is the widest on this list. The server exposes modular tools across SERP, keywords, backlinks, on-page, domain analytics, content analysis, and the DataForSEO Labs estimates. That is hundreds of low-level endpoints, with tool names like serp_google_organic_live.

The MCP code is free. What you pay for is the data you pull, billed pay-as-you-go from your own DataForSEO account, which needs a $50 minimum deposit to start. So “free” means free to run, not free to use.

The trade is curation. This is a raw developer tool. You bring your own account, manage credentials, and get the full firehose of endpoints with nothing filtered or pre-shaped for you. That is exactly what a developer building a custom workflow wants, and exactly what a non-technical marketer does not.

Verdict: the right pick if you are technical and want the raw pipe. Most people want something built on top of it instead of running it themselves, which is what ContextBolt SEO is.

3. Ahrefs MCP: the premium option if you already pay for Ahrefs

Best for: teams and agencies that already subscribe to Ahrefs.

Ahrefs released an official MCP server that connects its data to Claude, ChatGPT, Cursor, and Copilot. Setup in Claude Code is a single command pointed at the Ahrefs endpoint, and from there your agent can run keyword research, competitive analysis, content gap checks, on-page recommendations, and backlink audits in plain English.

Ahrefs built its name on a huge backlink index, and the MCP exposes that alongside keyword, SERP, content, and on-page data. If you already pay for an Ahrefs plan and want all of it inside your agent, this is the way to get it.

The catch is the price model. Ahrefs MCP is available on the paid Lite, Standard, Advanced, and Enterprise plans, which start around $129 a month. The MCP is a feature of the subscription, not a cheaper way in. You are paying dashboard prices and getting the agent access on top.

Verdict: if Ahrefs is already in your stack, turn the MCP on today. If you are picking a tool specifically to dodge dashboard prices, this is not the one, and our best Ahrefs alternatives round-up covers the cheaper picks.

4. Semrush MCP: live Semrush data, native in ChatGPT

Best for: Semrush subscribers, especially anyone who lives in ChatGPT.

Semrush ships an official remote MCP server that brings its keyword, traffic, and competitive data into your agent. It supports OAuth by default, with API key auth as a fallback, and it shows up as a built-in connector inside ChatGPT for Plus, Pro, and Business users.

That ChatGPT integration is the standout. For a lot of people, “set up an MCP server” still sounds like a config-file chore. With Semrush, ChatGPT users flip on a connector and start asking about rankings and competitors with nothing to install. The community version of the server exposes upward of 70 tools for people who want the full surface.

Like Ahrefs, it rides on a paid subscription. Semrush plans start at $139 a month, but the MCP is not on that tier. For a new account the qualifying plan is Starter at $199, so that is the real entry price, not a discount on it. The data is deep and the keyword database is enormous, but you are buying the platform first and getting agent access as a bonus. If you are weighing that bundled server against a standalone one, we put the two side by side in Semrush MCP vs ContextBolt SEO.

Verdict: the fit if you already pay for Semrush and work mostly in ChatGPT, where its built-in connector needs nothing installed. If you are looking at this list specifically to escape Semrush’s subscription, our best Semrush alternatives guide weighs the wider tradeoff.

5. SE Ranking MCP: the largest tool count behind one URL

Best for: teams who want keyword research, backlinks, audits, and AI visibility from a single connection.

SE Ranking ships an official hosted MCP server, and it exposes more than any other entry here, 180+ SEO and GEO tools covering keyword research, domain analysis, backlinks, site audits, competitor research, and AI search visibility.

The setup is the easiest on this list alongside ContextBolt. It is centrally hosted, so you authorize once and connect with one URL. No local install, no credentials to manage, no Node version to worry about. It works in Claude Web, Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Codex, Zed, and Gemini CLI.

The genuinely distinctive part is AI visibility sitting inside the same connection as the traditional SEO data. You can ask about your rankings and your brand’s presence across LLM engines without switching tools. Nightwatch and ContextBolt SEO do this too, and Ahrefs reaches Brand Radar through its MCP. SE Ranking pairs it with the largest tool count of the group.

The trade is that it is still a suite. MCP access is included in every SE Ranking subscription, so the honest way to read the price is the cost of the plan you need, with your data usage metered against that plan’s API credits. There is also an API-only route sold in credit blocks if you want the pipe without the dashboard, which is the closest thing here to a standalone option outside ContextBolt. SE Ranking prices in your local currency, so check the figure on their own page rather than trusting a converted one. The full breakdown is in our SE Ranking MCP pricing guide.

Verdict: the fit if you want the largest tool count behind one URL and you are comfortable buying a platform to get it. ContextBolt SEO covers keyword research, backlinks, audits and AI visibility at $35 without the platform.

6. Serpstat MCP: hosted or local, at mid-market prices

Best for: agencies and in-house teams who want a real suite behind their agent without Ahrefs money.

Serpstat runs an official MCP server exposing 63 tools across keyword research, competitor and gap analysis, backlink audits, site and page audits, rank tracking, and client reporting.

The useful quirk is that it ships in two shapes. The HTTP version is a one-click OAuth connection that works in Claude Web, Desktop, and Mobile plus ChatGPT. The STDIO version runs locally through Node with your own API token, which never leaves your machine, and works in Claude Desktop, Claude Code, Cursor, and Gemini CLI. Nothing else on this list gives you both a zero-install path and a keep-your-credentials-local path from the same vendor.

That matters more than it sounds. Agencies handling client data often cannot route API tokens through a third-party OAuth flow, and the local option solves that without giving up the tooling.

Pricing runs on API credits against a Serpstat plan, with a seven-day free trial and no card required, so you can measure your real credit burn before committing. Serpstat sits below Ahrefs and Semrush on price while still covering the full suite surface, which is the whole reason to look at it.

Verdict: the pick if your API token has to stay on your machine and you want a suite behind it at mid-market prices. It is still a suite bill, and the research still scrolls out of the chat. ContextBolt SEO keeps it on its own dashboard at $35.

7. Nightwatch MCP: rank tracking that connects to AI citations

Best for: people whose main job is watching positions move, across Google and the AI engines.

Nightwatch is a rank tracker first, and its official MCP server reflects that. The hosted endpoint at mcp.nightwatch.io/sse exposes live SERP positions across Google, Bing, and YouTube in a very large location set, plus keyword data, site audit findings including Core Web Vitals, competitor tracking, and report generation.

The feature worth the entry is Citation Intelligence. It tracks when ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews mention your brand, then ties those mentions back to your organic positions to show which rankings are actually feeding AI citations. That link between the two is the thing most AI-visibility tools skip, and it answers a question the others leave open, not just whether you are cited but what ranking earned it. Measuring citations is one half of the job. Earning them is the other, and that is what answer engine optimization covers.

The limits are the flip side of the focus. There is no meaningful backlink index here, so this does not replace an Ahrefs or a DataForSEO for link work. And the pricing is suite pricing, starting at €79 a month on Starter and climbing through €159 and €399 tiers, which is the highest floor of any specialist on this list.

Verdict: the best pick if rank tracking is the core of your work and you want AI citations tied to it. Pair it with ContextBolt SEO for links and the rest of the research.

8. SEOptimer MCP: audits on demand, and nothing else

Best for: consultants who mainly need to audit a site fast and explain the findings to a client.

SEOptimer runs an official MCP integration built around one job. You point it at any URL, it runs an SEO audit, and you interrogate the results in chat instead of reading a PDF. Ask why a score is low and you get the reasoning, then follow-up questions without regenerating anything.

The narrowness is the point. There is no keyword research here, no backlink index, no rank tracking. If your work is “look at this site, tell me what is wrong, help me explain it”, this is the cleanest path to that, and the audit output is genuinely built for handing to a client.

The pricing needs care, and it is the reason this sits at 8 rather than higher. SEOptimer’s plans look cheap at $29, $39, and $59 a month, but those tiers ship only a 50-call testing quota. Real API access, which is what an MCP server consumes, is a separate add-on starting at around $100 a month. So the sticker price and the price to actually run this through an agent are very different numbers. Worth knowing before you plan around the $29.

Verdict: the right shape for audit-led consulting, as long as you price in the API add-on rather than the headline plan. It hands you the report; ContextBolt SEO runs the audit and the fixes in the same chat.

9. Google Search Console MCP: your own site’s real Google data

Best for: anyone who wants their site’s actual Google numbers in their agent, not estimates.

Every tool above sells estimates. Nobody outside Google has Google’s exact figures. A Google Search Console MCP server is the exception, because it reads the data Google reports to you directly, meaning impressions, clicks, average position, the queries and pages behind them, and index status.

There are several community and open-source GSC servers, and they connect through OAuth to your verified Google account. They are free. The only thing they cannot do is look at sites you do not own, because this is first-party data by definition. Picking between them is a real decision, and it comes down to whether you want to stand up a Google Cloud project yourself. The Google Search Console MCP guide compares the servers and both setup routes.

This is the most underrated entry on the list. Estimate tools tell you where to aim. GSC tells you what actually happened, which queries you already rank for, which pages are one position away from page one, which impressions never turn into clicks. Pairing it with an estimate tool is the whole game.

Verdict: a free must-have to run alongside an estimate tool. First-party truth plus directional estimates is a stronger setup than either alone, and ContextBolt SEO connects Search Console read-only with daily snapshots so both sit in one chat.

10. Google Analytics MCP: the downstream traffic story

Best for: closing the loop from rankings to traffic and conversions.

SEO does not end at a ranking. The point is traffic that does something. A Google Analytics MCP server connects your GA4 property so your agent can pull sessions, users, events, and conversions by channel and landing page. Google offers an official option, and community servers exist too. All free.

This is not a keyword research tool, and it should not be your only SEO server. It is the outcome half. Once you know what you rank for from GSC and what to target from an estimate tool, GA tells you whether the traffic you won actually converted.

The honest knock is that GA4’s data model is fiddly, and asking loose questions can return numbers that need a second look. Used with a clear question, it closes a loop nothing else here can.

Verdict: round out the stack with it once Search Console and an estimate tool are in place. On its own it is not an SEO research server.

Honorable mention SEO MCP servers

Moz MCP: There is no official Moz server yet, but community projects such as metehan777/moz-mcp wrap the Moz API so you can pull Domain Authority and keyword data into an agent. Worth knowing if Moz metrics are what your reporting is built on.

Coupler.io MCP: Not an SEO tool exactly, more a universal connector across hundreds of business data sources including the SEO platforms. Useful if your real problem is joining SEO numbers to revenue or ad data rather than pulling SEO numbers at all.

Community DataForSEO wrappers: Several open-source projects, such as Skobyn/dataforseo-mcp-server, wrap the DataForSEO API into a lighter, self-hosted server. Useful if you want fewer tools than the official one exposes and you are happy to run it yourself.

Similarweb MCP: Official, hosted, and pointed at traffic and audience data rather than rankings, though it does carry keyword tools too. The catch is that it needs a Business, Enterprise or API-only Similarweb plan and none of those have a published price, which is why it sits here rather than in the ten. Full breakdown in what the Similarweb MCP reads and what it costs.

Brave Search and Tavily MCP: Not SEO tools, but live web search servers that pair well when your research spills past keyword data into reading what is actually ranking. They show up in our best MCP servers for knowledge workers shortlist.

How to choose an SEO MCP server for your workflow

Pick the line that sounds like you.

If you do your own SEO and do not want a dashboard bill: ContextBolt SEO at $35 a month is the standalone option, the only one here that saves the research to its own dashboard, and it starts with a 7-day trial.

If you already pay for Ahrefs or Semrush: turn their official MCP on today. You are already paying for the data, so there is nothing to weigh.

If you need deep backlink data and you are technical: DataForSEO MCP gives you the widest coverage for the lowest per-call cost. ContextBolt SEO sits on the same data with the backlink overview, referring domains and gap finder already shaped, if you would rather not run the pipe.

If you want the largest tool count in one connection: SE Ranking exposes the most tools of anything here and folds AI visibility in beside the traditional data, at suite prices.

If you are an agency that cannot route client tokens through OAuth: Serpstat offers a local server where your API token stays on your machine, and the DataForSEO MCP does the same if you run it yourself.

If rank tracking is the actual job: Nightwatch, because it ties AI citations back to the positions that earned them.

If you mostly audit sites for clients: SEOptimer, priced honestly at the API add-on rather than the headline plan.

If you just want your own site’s real numbers: the Google Search Console MCP is free and the only source of first-party Google data here.

The strong free combo: Search Console plus Google Analytics gives you first-party data end to end. Add one estimate tool for the keyword and competitor side, DataForSEO if you are technical or ContextBolt SEO if you are not, and you have a complete stack. The full pattern, including which AI clients support all of this, is in Which AI Tools Support MCP in 2026.

The dashboards are not dead. But the data is leaving the dashboard, and the right SEO MCP server for you comes down to two questions. What do you already pay for, and how technical are you. If the answers are nothing and not very, start with ContextBolt SEO. If you already pay for a suite, its server is included, and the 7-day trial is still the cheapest way to find out what a dashboard that fills itself and a memory of last week’s lookups are worth to you.
