A Model Context Protocol (MCP) server implementation for DuckDB, providing database interaction capabilities through MCP tools.
It would be interesting to have LLM analyze it. DuckDB is suitable for local analysis.

## Overview

This server enables interaction with a DuckDB database through the Model Context Protocol, allowing for database operations like querying, table creation, and schema inspection.

## Components

### Resources

Currently, no custom resources are implemented.

### Prompts

Currently, no custom prompts are implemented.

### Tools

The server implements the following database interaction tool:

- **query**: Execute any SQL query on the DuckDB database
  - **Input**: `query` (string) - Any valid DuckDB SQL statement
  - **Output**: Query results as text (or success message for operations like CREATE/INSERT)

> [!NOTE]
> The server provides a single unified `query` function rather than separate specialized functions, as modern LLMs can generate appropriate SQL for any database operation (SELECT, CREATE TABLE, JOIN, etc.) without requiring separate endpoints.

> [!NOTE]
> When the server is running in `readonly` mode, DuckDB's native readonly protection is enforced.
> This ensures that the Language Model (LLM) cannot perform any write operations (CREATE, INSERT, UPDATE, DELETE), maintaining data integrity and preventing unintended changes.

## Configuration

- **db-path** (string): Path to the DuckDB database file
