# Custom Database

> Use this tool when you need to securely access and manage multiple databases, including PostgreSQL, MySQL, MongoDB, and Oracle, without exposing credentials to AI agents. It solves problems related to data analysis, business intelligence, and programmatic database access by providing a secure interface for executing queries with parameterized inputs. The tool accepts database connection configurations and query inputs, and outputs query results, making it ideal for use cases that require secure and credential-free database interactions.

## Description

This MCP server provides AI assistants with secure database access across PostgreSQL, MySQL, MongoDB, and Oracle databases without exposing credentials directly to the AI agents. Built using Python with FastMCP and database-specific connectors, it stores connection configurations in a local SQLite database and offers tools for managing database connections (add, remove, list) and executing queries with parameterized inputs. The implementation includes command-line configuration management, supports schema specification for Oracle databases, and handles MongoDB queries through JSON filter syntax, making it valuable for data analysis workflows, business intelligence tasks, and building AI assistants that need programmatic database access without manual credential management or direct database exposure.
