Safe-by-Default Oracle Database MCP Server in Rust

This repository provides a Rust-based MCP server designed for secure interaction with Oracle databases. It prioritizes safety through a fail-closed SQL guard and an engine-free architecture, ensuring robust operation for developers. The server supports both stdio and HTTP interfaces, offering flexibility in integration.

What it Does

The oraclemcp server acts as a secure intermediary for your Oracle database. It intercepts SQL queries, applying a fail-closed security policy to prevent unauthorized or malicious operations. By being engine-free, it minimizes external dependencies and potential attack vectors. The server exposes an API that can be accessed via standard input/output or over HTTP, allowing developers to integrate Oracle database functionality into their Rust applications or other systems with enhanced security.

Key Features

Safe-by-Default: Implements a fail-closed security model for SQL queries, meaning any query that cannot be explicitly validated as safe will be blocked.
Fail-Closed SQL Guard: A core component that rigorously checks and filters incoming SQL statements before they reach the Oracle database.
Engine-Free Architecture: Reduces complexity and potential vulnerabilities by not relying on external database engines or complex middleware.
Rust Implementation: Leverages Rust's memory safety and performance characteristics for a reliable and efficient server.
Flexible Interfaces: Supports both stdio for direct command-line interaction and HTTP for network-based access.

Who it's For

This tool is intended for AI builders and developers who require secure and reliable access to Oracle databases within their projects. It is particularly useful for scenarios where data integrity and security are paramount, such as in AI applications handling sensitive information or critical business logic. Developers building microservices, backend systems, or data processing pipelines that interact with Oracle databases will find this MCP server a valuable asset for enhancing their security posture.
