Mssql Writer

Connects Claude directly to Microsoft SQL Server for data operations without touching your schema. You get read access through queries and write capabilities for INSERT, UPDATE, and DELETE, but DDL commands are explicitly blocked so you can't accidentally drop tables or alter structures. Reach for this when you want Claude to manipulate production data through a safer subset of SQL operations. The read/write split with DDL restrictions makes it reasonable for scenarios where you need data access but want guardrails against schema changes. Built by Connor Britain and runs over stdio transport.
