What does the mssql mcp server do?

It connects Mssql to MCP-compatible AI assistants such as Claude and Cursor. Instead of copying data back and forth by hand, the assistant works with Mssql directly.

How do I install the mssql mcp server?

Run it through your MCP client's configuration using `uvx mssql-mcp-server`. Add the server block to Claude Desktop's config file (or use `claude mcp add` for Claude Code), restart the client, and the tools appear automatically. Full snippets are on this page.

What credentials does it need?

It reads `MSSQL_DRIVER`, `MSSQL_HOST`, `MSSQL_USER`, `MSSQL_PASSWORD`, `MSSQL_DATABASE` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

Mssql MCP Server — Setup, Tools & Config

What is the Mssql MCP server?

Mssql mcp server connects Mssql to AI assistants that speak the Model Context Protocol. MSSQL MCP Server is a Model Context Protocol (MCP) server that enables secure and structured interaction with Microsoft SQL Server (MSSQL) databases. It allows AI assistants to: - List available tables - Read table contents - Execute SQL queries with controlled access.

Comprehensive Logging — for monitoring queries and operations

Installing the mssql mcp server

The server is distributed via PyPI as mssql-mcp-server, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Configuration

The server reads 5 environment variables: MSSQL_DRIVER, MSSQL_HOST, MSSQL_USER, MSSQL_PASSWORD, MSSQL_DATABASE. Keep credentials in your client's env block or a secrets manager rather than committing them.

Where it fits

Database servers turn schema archaeology and ad-hoc reporting into conversation, which is why they tend to be the second or third server people install. Mssql sits in that group. Worth comparing against the other databases servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.

MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the mssql mcp server actually does with your data.
Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.
