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:

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
