    How to choose the best SEO tool or MCP for you

    Start with the job

    Pick the source by task, not by brand. Keyword ideas and volumes come from the Google keyword tools, links and authority from Serpstat, SE Ranking, Moz, Majestic or Ahrefs, and AI visibility from DataForSEO.

    Read the unit

    Some tools charge per call, others per row, keyword or page. A per-call tool wins for a quick look at one domain; for long lists the price per row decides. Let your agent test with a small limit first.

    Live or historical

    Live calls show what ranks today. For trends, use the historical SERP, rank, traffic and search volume tools, and ask your agent which one it used before you draw conclusions.

    Country and language

    Keyword and SERP tools take a location and a language. Name your market up front, such as the US in English or Germany in German, because volumes and rankings differ per country.

    Quick picks: Google keyword ideas plus bulk volume for keyword research, Serpstat for a backlink overview, Moz for authority, DataForSEO for AI visibility and site audits, and Ahrefs when you want Ahrefs metrics without an Ahrefs account.

    Why use Agensi instead of separate SEO MCPs?

    DataForSEO, SE Ranking, Serpstat, Ahrefs and Semrush each run their own MCP server, and each one needs its own account and its own plan, credits or API units. That works for a team that lives in one tool. Most SEO questions need two or three sources. We put them behind one connection and one balance: your agent picks the tool for each job, runs it from your balance while it covers the price and tells you what each call cost. No API keys, no SEO tool subscriptions, and failed calls are free.

    When another way is the better choice. The official MCP server is the better choice when you already pay for Ahrefs, Semrush or SE Ranking and run hundreds of queries a day. Your plan then covers the calls, and you get that tool's full feature set inside your own account. Agensi fits better when you need data from several sources a few times a week and don't want a subscription for each.

    Set up in your AI agent

    Connect your AI agent to Agensi once, sign in and click Allow. After that it can use every tool: it runs one from your balance and tells you what it cost. No API keys or provider accounts.

    1. Open Settings, then Connectors, then Browse connectors and add Agensi (or Add custom connector and paste https://mcp.agensi.io/mcp/auth).
    2. Sign in to Agensi and click Allow. One agent per account: connecting a new one disconnects the old one.
    3. Ask for what you want, for example: "Find 30 keyword ideas for running shoes for flat feet in the US, in English, with volume and difficulty, and show who ranks in the top 3 for the 5 biggest." Top up from $5 if your balance is low; failed uses are free.

    Grok, VS Code, GitHub Copilot, Cline, Kiro and other agents with remote MCP and sign-in work too: see the setup guide.

    SEO MCP: frequently asked questions

    An SEO MCP server is a connector that lets an AI agent such as Claude, ChatGPT or Cursor pull SEO data by itself: keyword volumes, Google results, backlinks or authority scores. Connector and MCP server are two names for the same thing. With Agensi, one connection gives your agent every SEO tool on this page.

    It depends on the job. For keyword research we start with the Google keyword tools, for backlinks with Serpstat and Moz, and for AI visibility with DataForSEO. If you already pay for Ahrefs or Semrush and use it daily, their own MCP server makes sense. If you need several sources now and then, one connection is simpler.

    Yes. Ahrefs tools such as Domain Rating, organic keywords, top pages, backlinks and keyword metrics are in our catalog, paid per use from your Agensi balance, with no Ahrefs account or API key. Semrush is not in our catalog yet. If you have an Ahrefs plan and work in its projects every day, the Ahrefs MCP server is the better fit.

    Your agent runs each tool from your Agensi balance while it covers the price, then tells you what it found and what it cost. In Dashboard → Balance you can have it ask first, or only above an amount per use and per day, and set spending limits per use, per day and per month. Failed calls are free.
