The phrase SEO agent is being used for two very different things, and the difference matters before you connect anything to your site. One is an assistant that can look at your real data and help you decide what to do. The other is an autonomous system that goes off and changes your website. MrKeyword is firmly the first.
Here is what the AI SEO agent version of this actually is: your assistant — Claude, Cursor, or any MCP client — plus MrKeyword's 24 tools. Ask it a question and it queries your workspace: your Search Console performance, your tracked positions, the queries you appear for, what the last crawl found. It answers with real rows, each carrying a source and an as-of date. That is an agent in the useful sense: something that can take a goal, choose which data to look at, and come back with an argued answer.
What it is not: there is no MrKeyword process that edits your pages, publishes content, changes your Google or Bing accounts, or acts while you are asleep. 19 of the 24 tools are reads. The other 5 change something inside MrKeyword only — tracking a keyword, setting a target page, adding an annotation, starting a crawl, running a saved report — and only for a token created with “Allow this token to make changes” ticked, with every call written to the workspace audit log.
We are spelling this out because “AI SEO agent” is currently being sold as autonomy, and autonomy pointed at a production website is a bigger promise than most tools can keep. The judgement and the publishing stay with you. What changes is that the judgement now happens with your actual numbers in front of it instead of a guess.
