## What it 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.
