Seonio MCP: Connect Live SEO Data to ChatGPT, Claude, Cursor and Other AI Assistants

Updated 13 October 2026: 22 tools, current prices and plans.

Seonio MCP lets your AI assistant look up live SEO data while you chat. Connect ChatGPT, Claude, Cursor or another MCP client to https://seonio.com/mcp, and your assistant can check search volumes, read Google results, compare competitors and inspect backlinks for you. Each lookup costs the same as in the Seonio API, from $0.001, and a free account comes with a $1 testing balance.

Ask SEO questions in plain language

MCP (Model Context Protocol) is a standard way for AI assistants to use outside tools. Once Seonio is connected, you don't copy data into your prompt. You ask a question, and the assistant picks the Seonio tools it needs.

For example, you can ask: “Who are the organic competitors of example.com, and which of their keywords show commercial intent?” The assistant can call website_competitors, then website_ranking for each competitor, then keywords_intent, and summarize what it found.

Use it to:

• Plan content. Expand a seed keyword, group the ideas into clusters and check the intent of each one.
• Check a competitor. Compare organic traffic, ranking keywords, authority scores and backlinks.
• Write a brief from today's results. Read the current top results for a keyword as Markdown and look for gaps.
• Review a page. Run an on-page SEO check on its URL and ask the assistant what to fix first.

Connect Seonio to your AI assistant

The server address is the same for every app: https://seonio.com/mcp.

• ChatGPT and Claude: add Seonio as a custom connector and sign in to Seonio in your browser. There's no key to copy.
• Developer tools such as Claude Code, Codex, Cursor and VS Code: add the server address. If a tool can't sign in through the browser, it can send your Seonio API key as Authorization: Bearer <apikey>.

The steps differ by app and change from time to time, so follow the guide for your app on the Seonio MCP setup page. Your API key is under Settings in your Seonio account, and the same key works for the REST API.

Choose the right tool

Your assistant chooses tools on its own, but knowing them helps you ask better questions and estimate the cost. All tools only read data.

Know what you pay

MCP, the REST API and the Seonio website share one balance and the same prices. There's no separate MCP plan.

• Try it for free. A free account gets a $1 testing balance, once per person, with no card or subscription.
• Use a plan for regular work. Starter ($15 a month), Pro ($30) and Business ($60) include $15, $37.50 and $90 of usage every month. Included usage doesn't carry over to the next month. On any plan, Extra Usage packs add balance that's valid for one year.
• Know the order. Seonio spends your testing balance first, then your included monthly usage, then Extra Usage, starting with the pack that expires first.
• No overage bills. If your balance runs out, requests pause until your plan renews or you add an Extra Usage pack. On a free account, start a plan to continue.

A lookup that finds no data, such as a domain without backlinks, still costs the normal price, because the answer is real information. If a lookup fails on our side, you aren't charged and the assistant gets an error instead of an empty result. Requests for an unsupported country or a domain that doesn't exist are refused at once, without a charge.

Before a large job, ask your assistant to check account_balance. The pricing page always has the current plans and prices.

Check your request limit before automating a job

MCP and the REST API allow a set number of requests per second, depending on your plan: 5 on a free account, 10 on Starter, 15 on Pro and 20 on Business. A request above the limit gets a “too many requests” error (HTTP 429) and is never charged.

Get started

Create a free account, then follow the guide for your app on the Seonio MCP setup page. If you'd rather call the tools from your own code, see the REST API documentation.
