OpenSEO is an open source SEO platform providing keyword research, backlink analysis, rank tracking, technical site audits, and AI visibility monitoring, with direct access for AI agents over 📝Model Context Protocol (MCP).
The platform covers the standard SEO toolchain — keyword volume and difficulty metrics, competitor analysis, backlink inspection, rank position tracking, and crawl-based technical auditing — plus tracking for whether a site surfaces in AI-generated search results. It is positioned explicitly against incumbent subscription tools such as 📝Ahrefs and 📝Semrush, on both cost and openness: the codebase is 🏷️#open-source and self-hostable at no cost, while the hosted version bills by usage rather than a fixed monthly seat.
Its differentiating choice is the MCP server, which exposes live SEO data as tools an agent can call directly rather than as a dashboard a human reads. Documented clients include Claude, Codex, OpenClaw, OpenCode, and Gemini. That design puts OpenSEO in a small category of SEO tools built agent-first, where the primary consumer of the data is a model doing research inside an editor rather than an analyst reading a report.
