MCP server for Microsoft SQL Server — schema discovery, profiling, safe writes, and DDL

VerifiedSTDIODesktop onlyDatabases

Overview

AI-generated overview

Lets an assistant inspect a Microsoft SQL Server database and run profiling, safe writes, and DDL against it.

What you can do
This MCP server connects an assistant to Microsoft SQL Server. According to its registry description it supports schema discovery, profiling, safe writes, and DDL. No individual tools are listed in the manifest, so the exact operations are not shown.
When to use it
Worth adding when an assistant needs to explore a SQL Server schema, profile tables, or make controlled changes and schema updates during database work. Less useful if you only need read-only queries or do not use Microsoft SQL Server.
Requirements
Runs locally as a stdio process started with Node.js from the npm package @connorbritain/mssql-mcp-server. Desktop only. No environment variables, headers, or authentication are declared in the manifest, so the connection details for the SQL Server instance are not shown.
Before you install
The description mentions safe writes and DDL, so the assistant can change or delete data and alter schema; review what it is allowed to run and use a least-privilege database account. No credentials are declared in the manifest, so how the connection is authenticated is not shown here.

Installation

In SourceWeft

  1. Open Mssql in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Tools

0
SourceWeft has not started this package in its sandbox yet, so its tools are not known.

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
