* MCP Tools: OTTO Pipeline Tools |
| 4 |
* |
| 5 |
* Provides three MCP tools that close the loop for AI-driven SEO work: |
| 6 |
* 1. Trigger Otto Optimization — runs the full OTTO pipeline (warm |
| 7 |
* transient → SEO DB sync → plugin sync → cache purge → cache warm → |
| 8 |
* CDN purge) for a URL or post. |
| 9 |
* 2. Get Otto Status — returns the current OTTO state for a URL or post |
| 10 |
* (enabled flag, exclusion, transient warmth, last-written meta, |
| 11 |
* persistence settings, plugin sync timestamps). |
| 12 |
* 3. Verify SEO Output — fetches the live rendered HTML for a URL and |
| 13 |
* compares the rendered head tags against stored post meta. |
