## Overview
Over the past week, the #meta.discourse.org AI category saw **lively discussions** across three broad areas:
1. **New and evolving features** – from the community-driven design of a Discourse Model Context Protocol ([MCP](https://meta.discourse.org/t/-/364859/20?silent=true)) to improvements in ask.discourse history management and AI-driven content localization.
2. **Plugin innovation** – with the release of a customizable summary-gist plugin and ongoing work around AI bot personas, PDF support, and potential persistent memory enhancements.
3. **Bug fixes and stability** – several #Bug reports addressed AI spam misclassifications, embedding toggle errors, and a critical 500 Internal Server Error during manual AI configuration.
Below are the **10 most interesting topics** from August 18–25, followed by a breakdown of **who posted where**.
