dbhub and mssql-mcp-server
These are complements—the zero-dependency Postgres/MySQL/SQL Server client (A) provides general-purpose database operations across multiple engines, while the specialized SQL Server MCP server (B) offers enterprise-focused schema discovery and administration tools that would work alongside A for comprehensive SQL Server management.

bytebase/dbhub
Zero-dependency, token-efficient database MCP server for Postgres, MySQL, SQL Server, MariaDB, SQLite.
Implements just two core MCP tools—`execute_sql` and `search_objects`—with optional custom parameterized operations defined in TOML config, minimizing token overhead for AI context windows. Supports stdio, HTTP, and SSE transports for integration with Claude Desktop, VS Code, Cursor, and other MCP clients, plus includes a built-in web workbench for direct database interaction. Enforces safety guardrails including read-only mode, row limits, and query timeouts while enabling secure multi-database connections through SSH tunneling and SSL/TLS.
