# Release: datasette-mcp 0.2 Source: [https://simonwillison.net/2026/Sep/1/datasette-mcp/](https://simonwillison.net/2026/Sep/1/datasette-mcp/) > - `"rows"`from`execute\_sql`is now an array of objects\. Previously it was an array of arrays\. This should help weaker models avoid losing track of which positional array element maps to which column\.[\#1](https://github.com/datasette/datasette-mcp/issues/1) - Now depends on`mcp\>=2\.1\.1`\. This is the first non\-alpha release of the plugin\. I'm confident it's ready as I've been using it quite a bit myself\.
