### Description (declared)

# pyodbc MCP Server

A [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) server that provides **read-only** access to Microsoft SQL Server databases using **Windows Authentication**.

Built for environments where:
- 🔐 **Windows Authentication is required** (no username/password storage)
- 🛡️ **Read-only access is mandated** by IT security policy
- 🖥️ **SQL Server is accessed from Windows workstations**
- 🤖 **AI assistants need safe database access** (Claude Code, etc.)

## Features

- **Windows Authentication** - Uses `Trusted_Connection` via pyodbc, no credentials to manage
- **Read-only by design** - Only SELECT queries allowed, dangerous keywords blocked
- **Comprehensive error handling** - Typed exceptions with retry logic for transient failures
- **Row limiting** - Prevents accidental large result sets (configurable, max 10,000)
- **Schema exploration** - 10 tools for tables, views, indexes, constraints, relationships, and more
- **MCP resources** - 5 URI-based endpoints for quick data access
- **Configurable** - CLI arguments, TOML config files, or environment variables
- **Production-ready** - Query timeouts, connection retries, comprehensive logging
