A native macOS AI harness with MCP server support for local/cloud models, agents, and tools.
Overview
Osaurus is a comprehensive AI framework built in Swift for macOS, designed to provide a personal AI experience with persistent memory, autonomous agents, and cryptographic identity. As an MCP server, it exposes tools through a stdio bridge, enabling compatibility with MCP clients. The application supports various AI models including local MLX-optimized models, Apple's Foundation Models, and cloud providers like OpenAI and Anthropic. Its sandboxed environment allows safe code execution in isolated Linux VMs, making it suitable for both personal and professional use cases requiring security and privacy.
