About SQL MCP Server (Go)

What is SQL MCP Server (Go): Lightning-Fast SQL, Scalable Efficiency?

Imagine a superhero sidekick for your PostgreSQL databases—this is SQL MCP Server (Go). Built in Go, it’s the Swiss Army knife of database access tools, letting AI models and MCP clients query your PostgreSQL databases even through SSH bastions. Think of it as your secure, fast, and flexible bridge between AI and your data vaults.

How to Use SQL MCP Server (Go): Lightning-Fast SQL, Scalable Efficiency?

Ready to get your SQL game on? Here’s the 30-second elevator pitch:

Clone the repo and build it with go build.
Configure your DB details in .env (like a wizard setting up a spell).
Run it and send SQL via STDIO—your queries will be faster than a caffeine rush.

Sample input? Just a JSON blob asking for data. Output? A neat JSON response—error-free or not, it’ll tell you straight.

Content

SQL MCP Server (Go)

This project provides a Go implementation of a Model Context Protocol (MCP) server that enables language models and other MCP-compatible clients to query PostgreSQL databases—via SSH bastion tunnels when required.

Built for flexibility and secure database access, it supports AWS RDS with read-only transactions and stdin/stdout-based communication, making it suitable for local, containerized, or AI-driven use cases.

Features

🔒 SSH bastion support for secure access to private RDS instances
🐘 PostgreSQL read-only query engine using pgx
📡 STDIO-based MCP protocol transport
🧠 Compatible with memory-bank-mcp-server
⚙️ Easily configurable via .env or environment variables
🧪 Fully testable with mocks and table-driven tests

Installation

git clone https://github.com/your-org/sql-mcp-server.git
cd sql-mcp-server
go build -o sql-mcp-server

Configuration (Optional .env file)

DB_USER=postgres
DB_PASS=yourpassword
DB_HOST=localhost
DB_PORT=5432
DB_NAME=mydatabase
USE_SSH_TUNNEL=true
SSH_BASTION_HOST=bastion.example.com
SSH_BASTION_USER=ec2-user
SSH_PRIVATE_KEY_PATH=~/.ssh/id_rsa

Usage

./sql-mcp-server

Sample Input

{
  "type": "call_tool",
  "params": {
    "name": "query",
    "arguments": {
      "sql": "SELECT * FROM users LIMIT 10"
    }
  }
}

Sample Output

{
  "content": [
    {
      "type": "text",
      "text": "[{\"id\":1,\"name\":\"Alice\"}]"
    }
  ],
