OpenSEO MCP & Agent Skills
OpenSEO exposes an MCP server so AI agents like Claude Code, OpenClaw, and Hermes can use your SEO data directly. Agent Skills are reusable workflows that guide your agent through SEO tasks using the MCP.
Self-Hosting
OpenSEO supports two self-hosting paths:
- Simple: Docker for personal use on your own machine (recommended for getting started). See
docs/SELF_HOSTING_DOCKER.md. - Advanced: Cloudflare for internet-facing self-hosting across multiple devices or with your team (works on the free plan). See
docs/SELF_HOSTING_CLOUDFLARE.md.
Either way, you need a DataForSEO API key to get SEO data. See docs/DATAFORSEO_API_KEY.md.
Costs
OpenSEO needs a DataForSEO API key so that you can get SEO data. You pay them directly when self hosting.
When you self host, your costs will be slightly lower than the estimates on our website. The way the hosted service makes money is by charging 28% extra for every request we make to DataForSEO.
Local Development
