What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Databases & datasets
You need to fill in: MSSQL_CONNECTION_STRING

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
You fill in yourself: MSSQL_CONNECTION_STRING

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

PyPIPython’s uv installed (for the uvx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "sqlserver": {
      "command": "uvx",
      "args": [
        "sqlserver-mcp-tools"
      ],
      "env": {
        "MSSQL_CONNECTION_STRING": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add sqlserver --env MSSQL_CONNECTION_STRING=your-value -- uvx sqlserver-mcp-tools

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "sqlserver": {
      "command": "uvx",
      "args": [
        "sqlserver-mcp-tools"
      ],
      "env": {
        "MSSQL_CONNECTION_STRING": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "sqlserver": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "sqlserver-mcp-tools"
      ],
      "env": {
        "MSSQL_CONNECTION_STRING": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

MSSQL_CONNECTION_STRING secret required env
String de conexão ODBC para o SQL Server

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Common questions

Is SQL Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: MSSQL_CONNECTION_STRING

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.8) reached the registry 26 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

mcp-sqlserver

Servidor MCP (Model Context Protocol) para SQL Server, com controle de permissões e modo somente-leitura por padrão. Permite que agentes de IA (Claude, opencode e outros clientes MCP) consultem e administrem bancos SQL Server de forma segura.

Segurança

Credenciais nunca expostas ao LLM — a string de conexão é lida do ambiente e nunca aparece nas respostas nem nos logs.
Somente leitura por padrão — a ferramenta consulta bloqueia DDL/DML (INSERT, UPDATE, DELETE, DROP, etc.).
Escrita sob demanda — ferramentas de escrita (executar_update, executar_ddl, etc.) só são expostas quando o usuário da conexão possui permissão de escrita (roles sysadmin, db_owner, db_datawriter ou db_ddladmin), e exigem confirmação explícita antes de cada execução.

Pré-requisitos

Python 3.10+
Driver ODBC Driver 18 for SQL Server:
macOS: brew install msodbcsql18
Windows/Linux: instale o driver correspondente da Microsoft

Instalação

Via PyPI:

pip install sqlserver-mcp-tools

Ou, sem instalar nada (executa direto do PyPI com cache):

uvx --from sqlserver-mcp-tools mcp-sqlserver

Configuração

O servidor lê a string de conexão das seguintes fontes, em ordem de prioridade:

Variável de ambiente MSSQL_CONNECTION_STRING
Variável de ambiente MSSQL_ENV_FILE apontando para um arquivo .env
Arquivo .env no diretório de trabalho (ou na raiz do projeto)

Exemplo de string de conexão:

DRIVER={ODBC Driver 18 for SQL Server};SERVER=localhost,1433;DATABASE=seu_banco;UID=seu_usuario;PWD=sua_senha;TrustServerCertificate=yes

Uso com clientes MCP

Claude Desktop

Adicione ao claude_desktop_config.json:

"mcpServers": { "mcp-sqlserver": { "command": "uvx", "args": ["--from", "sqlserver-mcp-tools", "mcp-sqlserver"], "env": { "MSSQL_CONNECTION_STRING": "DRIVER={ODBC Driver 18 for SQL Server};SERVER=...;DATABASE=...;UID=...;PWD=...;TrustServerCertificate=yes" } } } }

Se instalou via pip install, pode usar o entry point diretamente:

"mcpServers": { "mcp-sqlserver": { "command": "mcp-sqlserver", "env": { "MSSQL_CONNECTION_STRING": "DRIVER={ODBC Driver 18 for SQL Server};SERVER=...;DATABASE=...;UID=...;PWD=...;TrustServerCertificate=yes" } } } }

OpenCode

No opencode.json do projeto:

"mcp": { "sqlserver": { "type": "local", "command": ["mcp-sqlserver"], "environment": { "MSSQL_CONNECTION_STRING": "DRIVER={ODBC Driver 18 for SQL Server};SERVER=...;DATABASE=...;UID=...;PWD=...;TrustServerCertificate=yes" } } } }

Alternativa: apontar para um arquivo .env local, mantendo a senha fora do JSON:

"mcp": { "sqlserver": { "type": "local", "command": ["mcp-sqlserver"], "environment": { "MSSQL_ENV_FILE": "/caminho/para/seu/.env" } } } }

Servidor HTTP (Streamable HTTP)

Além do modo local (stdio), o servidor pode ser executado como um MCP remoto via Streamable HTTP, expondo o endpoint /mcp. Instale com o extra server:

pip install 'sqlserver-mcp-tools[server]'

Inicie o servidor:

MSSQL_CONNECTION_STRING="DRIVER={ODBC Driver 18 for SQL Server};SERVER=...;DATABASE=...;UID=...;PWD=...;TrustServerCertificate=yes" \

mcp-sqlserver-http

Opcionalmente, ajuste host/porta com MCP_HOST (padrão 0.0.0.0) e MCP_PORT (padrão 8090). O endpoint MCP fica em http:// : /mcp.

Para consumir remotamente no opencode:

"mcp": { "sqlserver": { "type": "remote", "url": "http://10.177.51.228:8090/mcp" } } }
