MCP server for Microsoft SQL Server — read and data write operations, no DDL

VerifiedSTDIODesktop onlyDatabases

Overview

AI-generated overview

Local MCP server that lets an assistant read from and write data to Microsoft SQL Server, without DDL schema changes.

What you can do
  • Read data from Microsoft SQL Server tables and views.
  • Write and modify row data in existing tables.
  • No DDL: schema objects such as tables and columns are not created or altered.
  • Tool list is not published, so exact operations are not documented.
When to use it
Useful when an assistant needs to query or update data in an existing Microsoft SQL Server database as part of a local workflow, and you want writes limited to data rather than schema changes.
Requirements
Runs as a local process via npm package @connorbritain/mssql-mcp-writer with Node.js, over stdio. Desktop only; no web execution. No authentication, environment variables or headers are declared, so connection details for the SQL Server instance are not specified in the listing.
Before you install
It can write and modify data in your database, so point it at a non-production or restricted account where possible and review changes. No credentials are declared in the manifest, so you will need to supply database access yourself; keep such secrets out of shared configuration. The tool list is not published, so verify what it can execute before use.

Installation

In SourceWeft

  1. Open Mssql Writer 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.

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.

    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.
