d365fo-mcp-server

Active·★ 163·MIT·Updated 2026-10-20

This server addresses the challenge of AI assistants generating incorrect X++ code for Dynamics 365 Finance & Operations by pre-indexing the entire D365FO installation. It exposes over 20 specialized tools that validate every reference against your real metadata, ensuring generated code compiles correctly.
