SQLite MCP Server

Features

• **Schema Exploration** - List all tables in the database - View detailed schema information for specific tables - Examine column types and constraints

• **Data Management** - Execute read-only SQL queries - Perform data modifications (UPDATE, INSERT, DELETE) - Safe execution with error handling

• **Data Analysis** - Basic statistical analysis (row counts, null counts, numeric stats) - Detailed analysis including categorical data distributions - Automatic type detection and appropriate statistical measures

Prerequisites

• Python 3.8 or higher

• SQLite database file

• [Claude Desktop](https://claude.ai/download) (optional, for desktop integration)

Installation

1. First, ensure you have the required Python packages:

1. Download the SQLite MCP server script:

1. For Claude Desktop integration:

Usage

• Locate the claude_desktop_config.json file and add below to the mcpServers section

• change the paths to the correct ones for your system.

• Set database location in DB_PATH variable in the .env file.

Available Resources

• `schema://tables` - Lists all available tables in the database - Example response: ``` Available tables: - users - products - orders ```

• `schema://{table}` - Returns detailed schema information for a specific table - Example response: ``` Table: users Create Statement: CREATE TABLE users ( id INTEGER PRIMARY KEY, name TEXT NOT NULL, email TEXT UNIQUE ) Columns: - id (INTEGER) NOT NULL PRIMARY KEY - name (TEXT) NOT NULL - email (TEXT) ```

Available Tools

query

update_data

analyze_table

• `table`: Name of the table to analyze

• `analysis_type`: Either 'basic' or 'detailed'

Security Considerations

1. Input validation for all SQL operations

2. Read-only queries are separated from data modifications

3. Database connection error handling

4. SQL injection protection through parameterized queries

Error Handling

• Database connection failures

• Invalid SQL syntax

• Table not found errors

• Permission issues

• Type mismatches
