Sql Augur MCP Server
An MCP server that gives AI assistants safe, read-only access to SQL Server databases. Every query is parsed into a full AST using Microsoft's official T-SQL parser - not regex - so comment injection, string literal tricks, and encoding bypasses are blocked at the syntax level. Its 31 documented tools cover blitz, plan, diagram, cache.
People who work with blitz, plan and diagram and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in C#.

02 · What Sql Augur can do
Prose above is summarized from the project's README and registry record - no invented capabilities.
What you can build
With this server connected, an agent can list available SQL Server instances configured in appsettings.json, list all databases on a named server with names, IDs, states, and creation dates, read the estimated or actual XML execution plan for a SELECT query, and list views, stored procedures, functions, and trigger. Filterable by type and schema.
