MCP.Pizza Chef: cnych

Four things come back from this one: the sites linking to a domain, keyword ideas built out from a seed word, a difficulty score for a phrase, and a rough traffic estimate with top pages and countries. All of it is scraped out of Ahrefs by getting past their bot check, which means a paid CapSolver account is required even though the project calls itself free. Nothing in the code has changed since April 2025, so expect it to break. Cursor is the only app it documents.

seo-mcp FAQ

Is this still being maintained?
No. The code has not changed since April 2025, and because it works by slipping past Ahrefs' bot check, that gap makes breakage likely. Test it before relying on it.
Is it actually free?
The tool is free, but it cannot run without a CapSolver account, and CapSolver charges for every puzzle it solves. Budget a small running cost.
Do I need to pay for Ahrefs too?
No, and that is the whole trick — it reads Ahrefs data without a subscription. The author labels the project educational and asks people not to abuse it.
Can I use this to research keywords before writing an article?
Yes — give it a seed phrase and it returns related terms with search volume and a difficulty score.
Can it change anything on my website?
No. Every tool only reads and reports numbers.
Which apps does it work in?
Cursor is the only one with written instructions, though any app that takes a standard MCP setup snippet should work.
What do I need installed?
Python 3.10 or newer, plus a short config block holding your CapSolver key.
