OnPage.dev — Claude Code MCP server: what it does, how to install
Hosted SEO MCP server that audits pages for Google and AI search engines, prepares metadata fixes, and sends changes directly to a CMS or pull request.
claude mcp add --transport http onpage https://onpage.dev/mcpWhat OnPage.dev does
OnPage.dev runs as a remote HTTP endpoint offering 37 built-in tools without an API key. It inspects pages for standard indexing and AI answer engines like ChatGPT and Perplexity. The audit checks bot crawler rules, the presence of llms.txt, Schema.org data, and core meta tags.
Instead of stopping at audit logs, the server prepares ready-to-apply fixes. You can push finished updates straight to a GitHub pull request or into content systems such as WordPress and Shopify. It retains site memory across separate chat sessions and links organic traffic drops to confirmed Google updates.
Because OnPage.dev runs remotely at https://onpage.dev/mcp, air-gapped environments without outbound internet access cannot use it.
What it helps with
- audit page readiness for AI search engines and web crawlers
- generate Schema.org structures and missing meta tags
- pinpoint Google algorithm updates behind traffic drops
- publish SEO fixes straight to a CMS or as a pull request
Example prompts for the agent
- Audit our pricing page for SEO issues and prepare meta tag fixes
- Create Product Schema markup and open a pull request with the change
- Check our llms.txt file to see if AI crawlers can access our content
