Had a fun new class of debugging problem yesterday. My MCP server was live on the new version. Health check confirmed it. The new tool schema was definitely there. ChatGPT was still seeing the OLD tool definition😂 I eventually got the catalogue to refresh, but apparently “have you cleared the cache?” now applies to AI tool schemas too.
