Best SEO MCP servers: DataForSEO, Ahrefs, Semrush

DataForSEO's official MCP server is the best pick for raw SEO data: Google results, keyword volume and backlinks, paid as you go from a prepaid balance that never expires. Ahrefs and Semrush run official remote servers for subscribers on their paid plans. Google has no official Search Console server. Through Locus Pro, an agent gets DataForSEO data as typed tools, priced per call from prepaid credits with no top-up minimum.

Which SEO MCP servers are worth using?

Four sources cover most SEO agent work: a raw data API, two SEO suites and your own Search Console data. Details and limits are from vendor pages on November 10, 2026.

Semrush is also in the Cursor Marketplace and the ChatGPT plugin directory. In Claude Code, add it with claude mcp add semrush https://mcp.semrush.com/v2/mcp -t http.

What SEO data can an agent get through Locus Pro?

Locus Pro wraps DataForSEO endpoints as separate, typed tools, so the agent does not have to build raw API requests. There is no top-up minimum. Each call is priced by request and carries a quote, and the final charge depends on the task DataForSEO runs, never more than that quote.

It suits agents that run SEO checks now and then, such as a weekly check on 100 keywords, or that mix SEO data with other vendors on one bill. These endpoints were in the Locus catalog on November 10, 2026:

What SEO data can an agent get through Locus Pro?
Data	Locus endpoint
Google organic results	dataforseo/serp-google-organic
Keyword search volume	dataforseo/search-volume
Keyword overview	dataforseo/dataforseo-labs-google-keyword-overview
Keyword ideas	dataforseo/dataforseo-labs-google-keyword-ideas
Backlinks for a target	dataforseo/backlinks-backlinks

How do you choose an SEO MCP server?

Start from the data you need, then the plan you already have.

Raw SERPs and keyword volume in bulk: DataForSEO's own server, since calls can cost less with your own DataForSEO account and API key.
Metrics from the Ahrefs or Semrush index: that vendor's server, on a plan you already pay for.
Your own site performance: a Search Console server, with your own Google OAuth client.
Occasional SEO checks, or SEO plus other data on one bill: Locus Pro.

Frequently asked questions

Is there a free SEO MCP server?

For your own sites, yes. Community Search Console servers are free and read your own data through your Google account. For market data, DataForSEO gives new accounts $1 of free trial credit.

Does Google have an official Search Console MCP server?

Not as of November 10, 2026. Google's own MCP repository lists servers for Google Analytics and other products, but not Search Console. The popular option is the community server AminForou/mcp-gsc.

Can I call the Ahrefs MCP server from my own scripts?

No. Ahrefs says custom scripts may not call the MCP endpoint. Use the Ahrefs API for scripts instead.

How does Locus Pro price a DataForSEO call?

Each call gets a quote first. After the call, Locus Pro charges for the task DataForSEO ran, and never more than the quote. You can also set a credit ceiling on the call.
