# MCP Database Query Server

An MCP (Model Context Protocol) server that lets a VS Code AI agent query databases through a structured, step-by-step workflow.

## Supported Databases

- **SQLite** — via Python's built-in `sqlite3` (always available)
- **PostgreSQL** — via `psycopg2` (optional — install `psycopg2-binary`)
- **MySQL** — via `mysql-connector-python` (optional)
- **Microsoft SQL Server** — via `pyodbc` (optional — requires ODBC drivers)

> **Note:** Only SQLite support is required to get started. The server loads database adapters lazily — missing optional drivers won't prevent the server from starting.

## Setup

### 1. Install dependencies

```bash
pip install -r requirements.txt
```

### 2. Configure connections

Edit `config.json` to add your database connections:

```json
{
  "connections": [
    {
      "name": "My Postgres",
      "type": "postgres",
      "host": "localhost",
      "port": 5432,
      "database": "mydb",
      "username": "user",
      "password": "
