Overview

Description from the maker (original English)

Execute raw SQL queries against SQL Server, SQLite, PostgreSQL, MySQL, and MariaDB.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

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: RawSqlMcp__Databases__Default__ConnectionString, RawSqlMcp__ConnectionStrings__Default

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: RawSqlMcp__Databases__Default__Provider, RawSqlMcp__Databases__Default__ConnectionString, RawSqlMcp__ConnectionStrings__Default

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

Which app do you use?

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": {
    "rawsqlmcp": {
      "command": "dnx",
      "args": [
        "RawSqlMcp",
        "--yes"
      ],
      "env": {
        "RawSqlMcp__Databases__Default__Provider": "your-value",
        "RawSqlMcp__Databases__Default__ConnectionString": "your-value",
        "RawSqlMcp__ConnectionStrings__Default": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add rawsqlmcp --env RawSqlMcp__Databases__Default__Provider=your-value --env RawSqlMcp__Databases__Default__ConnectionString=your-value --env RawSqlMcp__ConnectionStrings__Default=your-value -- dnx RawSqlMcp --yes

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": {
    "rawsqlmcp": {
      "command": "dnx",
      "args": [
        "RawSqlMcp",
        "--yes"
      ],
      "env": {
        "RawSqlMcp__Databases__Default__Provider": "your-value",
        "RawSqlMcp__Databases__Default__ConnectionString": "your-value",
        "RawSqlMcp__ConnectionStrings__Default": "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": {
    "rawsqlmcp": {
      "type": "stdio",
      "command": "dnx",
      "args": [
        "RawSqlMcp",
        "--yes"
      ],
      "env": {
        "RawSqlMcp__Databases__Default__Provider": "your-value",
        "RawSqlMcp__Databases__Default__ConnectionString": "your-value",
        "RawSqlMcp__ConnectionStrings__Default": "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

  • RawSqlMcp__Databases__Default__Provider env
    Database provider. Values: sqlserver, sqlite, postgres, postgresql, mysql, mariadb.
  • RawSqlMcp__Databases__Default__ConnectionString secret env
    Connection string for the named database.
  • RawSqlMcp__ConnectionStrings__Default secret env
    Obsolete. Use provider and connection string database settings instead.

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

Common questions

Is Raw SQL MCP 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: RawSqlMcp__Databases__Default__ConnectionString, RawSqlMcp__ConnectionStrings__Default

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 (0.1.0) reached the registry 4 months ago.

Which apps can use it?

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

What can I use instead?

In the same category: Supabase, MongoDB MCP Server, Elasticsearch MCP Server

Raw SQL MCP

Raw SQL MCP is a STDIO MCP server for executing raw SQL against SQL Server, SQLite, PostgreSQL, MySQL, and MariaDB.

[!IMPORTANT]

Use it carefully. The server does not protect you from destructive queries, expensive queries, SQL injection, missing pagination, or unsafe data exposure. Always review and approve queries before running them.

Installation

Run the server with dnx:

dnx RawSqlMcp

For a specific version:

dnx RawSqlMcp@0.0.2

Package: RawSqlMcp on NuGet

Configuration

Databases are configured with environment variables under RawSqlMcp__Databases__.

SQLite:

export RawSqlMcp__Databases__Local__Provider="sqlite"

export RawSqlMcpDatabasesLocal__ConnectionString="Data Source=/absolute/path/app.db"

PostgreSQL:

export RawSqlMcp__Databases__Reporting__Provider="postgres"

export RawSqlMcpDatabasesReporting__ConnectionString="Host=localhost;Port=5432;Database=reporting;Username=postgres;Password=postgres"

MySQL/MariaDB:

export RawSqlMcp__Databases__Shop__Provider="mysql"

export RawSqlMcpDatabasesShop__ConnectionString="Server=localhost;Port=3306;Database=shop;User ID=mysql;Password=mysql"

SQL Server:

export RawSqlMcp__Databases__Default__Provider="sqlserver"

export RawSqlMcpDatabasesDefault__ConnectionString="Server=localhost,1433;Database=master;User Id=sa;Password=Your_password123;TrustServerCertificate=True"

Optional command timeout, in seconds:

export RawSqlMcp__CommandTimeout=30

[!INFO]

The legacy RawSqlMcp__ConnectionStrings__Default="..." format is obsolete. It still works for compatibility and is interpreted as SQL Server.

Usage

Register the server in an MCP client as a STDIO server:

{

"servers": { "raw-sql-mcp": { "command": "dnx", "args": ["RawSqlMcp"], "env": { "RawSqlMcpDatabasesDefaultProvider": "sqlserver", "RawSqlMcpDatabasesDefaultConnectionString": "Server=localhost,1433;Database=master;User Id=sa;Password=Your_password123;TrustServerCertificate=True" } } } }

The server exposes tools for listing configured database names, reading schema metadata, and executing raw, parameterized, and scalar SQL queries.
