seo-mcp by cnych

A free SEO data service delivered over the Model Context Protocol, built on Ahrefs data. It exposes backlink analysis, keyword ideas and keyword research, traffic estimation with history and trends, popular pages and country distribution, and keyword ranking tracking to any MCP client. The service handles the whole retrieval process itself, including solving the CAPTCHA with CapSolver, authentication and response caching for faster repeat queries. Installation is possible from PyPI or manually, then you run the service and call it through the documented API reference, with a troubleshooting section for common problems. Written in Python and released under the MIT license as open source and free to use. It suits SEOs and developers who want Ahrefs-style numbers inside an AI assistant without opening a dashboard.
