## 🛠️ MCP Tools
The server exposes the following tools to LLMs:
### read_query
Execute a SELECT query on the database with built-in safety validations. Features:
- Query validation and sanitization
- Parameter binding support
- Row limit enforcement
- Results formatted as dictionaries
### list_tables
List all available tables in the database with their names.
### describe_table
Get detailed schema information for a specific table, including:
- Column names and types
- NULL constraints
- Default values
- Primary key information
## 🚀 Getting Started
Clone the repository:
```bash
git clone https://github.com/hannesrudolph/sqlite-explorer-fastmcp-mcp-server.git
cd sqlite-explorer-fastmcp-mcp-server
```
## 📦 Installation Options
You can install this MCP server in either Claude Desktop or the Cline VSCode plugin. Choose the option that best suits your needs.
### Option 1: Install for Claude Desktop
Install using FastMCP:
```bash
fastmcp install sqlite_explorer.py --name "SQLite Explorer" -e SQLITE_DB_PATH=/path/to/db
```
Replace `/path/to/db` with the path to your SQLite database file.
### Option 2: Install for Cline VSCode Plugin
To use this server with the [Cline VSCode plugin](http://cline.bot):
1. In VSCode, click the server icon (☰) in the Cline plugin sidebar
2. Click the "Edit MCP Settings" button (✎)
3. Add the following configuration to the settings file:
```json
{
"sqlite-explorer": {
"command": "uv",
"args": [
"run",
"--with",
"fastmcp",
"--with",
"uvicorn",
"fastmcp",
"run",
"/path/to/repo/sqlite_explorer.py"
],
"env": {
"SQLITE_DB_PATH": "/path/to/your/database.db"
}
}
}
```
Replace:
- `/path/to/repo` with the full path to where you cloned this repository (e.g., `/Users/username/Projects/sqlite-explorer-fastmcp-mcp-server`)
- `/path/to/your/database.db` with the full path to your SQLite database file
## 🔒 Safety Features
- Read-only access to SQLite databases
- Query validation and sanitization
- Parameter binding for safe query execution
- Row limit enforcement
- Progress output suppression for clean JSON responses
## 📚 Development Documentation
The repository includes documentation files for development:
- `mcp-documentation.txt`: Contains comprehensive documentation about the MCP server implementation and FastMCP framework usage.
This documentation serves as context when developing features and can be used with LLMs to assist in development.
## ⚙️ Environment Variables
The following environment variables must be set:
- `SQLITE_DB_PATH`: Full path to the SQLite database file you want to explore
