Afgong Sqlite Mcp Server

[MseeP.ai Security Assessment Badge]

SQLite Explorer MCP Server

An MCP server that provides safe, read-only access to SQLite databases through Model Context Protocol (MCP). This server is built with the FastMCP framework, which enables LLMs to explore and query SQLite databases with built-in safety features and query validation.

📋 System Requirements

• Python 3.6+
• SQLite database file (path specified via environment variable)

📦 Dependencies

Install all required dependencies:

# Using pippip install -r requirements.txt

Required Packages

• fastmcp: Framework for building Model Context Protocol servers

All dependencies are specified in requirements.txt for easy installation.

🛠️ 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:

git clone https://github.com/hannesrudolph/sqlite-explorer-fastmcp-mcp-server.gitcd 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:

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:

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:

{  "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
