SQLite MCP Server

Integrations

  • Built for the Bun JavaScript runtime environment, using it for dependency management, script execution, and server operation.

  • Includes ESLint integration through built-in scripts for running checks and automatically fixing issues.

  • Includes specific support for macOS with automatic configuration of Claude Desktop files in the macOS-specific application support directory.

SQLite MCP Server

Overview

A Model Context Protocol (MCP) server implementation that provides database interaction and business intelligence capabilities through SQLite. This server enables running SQL queries, analyzing business data, and automatically generating business insight memos.

Installation

  1. Install Bun if you haven't already
  2. Clone this repository
  3. Install dependencies:
    bun install
  4. Run the setup script to configure the server in Claude Desktop:
    bun run setup

The setup script will automatically add the server configuration to your Claude Desktop config file, located at:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Components

Resources

The server exposes a single dynamic resource:

  • memo://insights: A continuously updated business insights memo that aggregates discovered insights during analysis
    • Auto-updates as new insights are discovered via the append-insight tool

Prompts

The server provides a demonstration prompt:

  • mcp-demo: Interactive prompt that guides users through database operations
    • Required argument: topic - The business domain to analyze
    • Generates appropriate database schemas and sample data
    • Guides users through analysis and insight generation
    • Integrates with the business insights memo

Tools

The server offers six core tools:

Query Tools
  • read-query
    • Execute SELECT queries to read data from the database
    • Input:
      • query (string): The SELECT SQL query to execute
    • Returns: Query results as array of objects
  • write-query
    • Execute INSERT, UPDATE, or DELETE queries
    • Input:
      • query (string): The SQL modification query
    • Returns: { affected_rows: number }
  • create-table
    • Create new tables in the database
    • Input:
      • query (string): CREATE TABLE SQL statement
    • Returns: Confirmation of table creation
Schema Tools
  • list-tables
    • Get a list of all tables in the database
    • No input required
    • Returns: Array of table names
  • describe-table
    • View schema information for a specific table
    • Input:
      • table_name (string): Name of table to describe
    • Returns: Array of column definitions with names and types
Analysis Tools
  • append-insight
    • Add new business insights to the memo resource
    • Input:
      • insight (string): Business insight discovered from data analysis
    • Returns: Confirmation of insight addition
    • Triggers update of memo://insights resource

Development

Project Structure

  • src/index.ts: Main server implementation
  • src/logger.ts: Logging utility
  • scripts/setup.ts: Claude Desktop configuration script

Logging

The server maintains detailed logs in:

  • server.log: Located in the project root directory
  • Logs include timestamps, log levels (DEBUG, INFO, WARN, ERROR, FATAL), and structured metadata

Database

The SQLite database file is created at:

  • data.sqlite: Located in the project root directory
  • Created automatically if it doesn't exist

Available Scripts

  • bun run setup: Configure the server in Claude Desktop
  • bun run lint: Run ESLint checks
  • bun run lint:fix: Fix ESLint issues automatically
  • bun run inspect: Run the MCP inspector
