SEO tools for Claude: Semrush MCP or a pay-per-run server

SEO tools for Claude used to mean pasting exported spreadsheets into a chat window. That has changed. Through the Model Context Protocol, Claude Code and Claude Desktop can now call an SEO data service directly, run a report, read the result and act on it. Semrush has an MCP server, and so do smaller services built for this kind of use. The difference between them is mostly in how access is priced, and that shapes what an agent can afford to do.

Plans and prices were checked on the vendors' pages in October 2026.

What changes when the agent fetches the data

With a chat-only setup, a person decides which report to run, exports it, and hands it over. With MCP, the model picks the tool and the inputs. A prompt like "find our three closest search competitors and list keywords they rank for that we don't" becomes several tool calls the agent chains on its own: find competitors, pull their keywords, compute the gap, then write a content plan.

That shifts two things. Usage becomes bursty, since an agent may run ten reports in a minute and then nothing for a week. And cost control matters, since the person approving the work is no longer choosing each call.

Semrush's MCP: suite pricing

Semrush lists MCP access on its Starter plan, at $199 a month or $165.17 billed annually. The $139 SEO plan does not include it. Full API data integration is on Advanced, now a custom quote. Extra users start at $45 a month.

For a team that already lives in Semrush, connecting Claude to it is a natural step. The agent gets the same breadth the team uses: keyword research, competitor insights, tracking. For a developer or small team who wants Claude to look up a competitor now and then, it means buying a full suite tier to reach one interface.

seogeoaeo.ai: per-run pricing built for agents

seogeoaeo.ai takes the other approach and is the better fit for most agent setups. Every tool is an MCP tool named by its slug, every plan includes MCP and REST, and each run spends a fixed number of credits. Plans start at $29 a month for 2,000 credits. Agent runs cost the same as browser runs.

The tools an agent reaches for in place of Semrush:

Two parameters are there for unattended use. maxCredits makes the server refuse any run above a set price, so an agent cannot overspend on one call. idempotencyKey lets it retry a timed-out request without paying twice. Failed runs are refunded.

Setup in Claude Code is one command:

claude mcp add --transport http --scope user seogeoaeo https://seogeoaeo.ai/api/mcp --header "Authorization: Bearer YOUR_API_KEY"

The same account also covers AI search checks that matter more each year: which AI crawlers a site's robots.txt allows, llms.txt validation and generation, and AI Answer Visibility (120 credits), which asks ChatGPT, Perplexity and Gemini a customer question and reports whether your brand is named.

What the agent will not get

Per-run data has limits that Claude should be told about in its instructions. seogeoaeo.ai does not track rankings, keeps no link index of its own, and stores no history of how a site changed. It does not return the keywords a competitor bids on. Its figures are estimates from a third-party provider, so an agent should present them as estimates for comparison, not exact counts.

Other MCP-capable options

• SE Ranking Core, $129 a month: MCP access and 25K API credits, plus 2,000 keywords tracked daily.
• Ahrefs Lite, $129 a month: API and MCP access with 1,000 credits per user.

Both suit agents that need daily tracking data alongside research.

Which setup fits

If Claude is helping a team that already works in Semrush daily, use Semrush's MCP and pay for Starter. If Claude is the one doing occasional competitor research, a credit plan with MCP included costs less and gives the agent a hard price ceiling on every call.
