exobrain 0.2.1

A toy AI assistant with agent capabilities and file system access

ExoBrain

A toy AI assistant with tool calling capabilities and file system access, running in your terminal with or without TUI.

Features

• 💻 TUI Interface - Terminal UI based on Textual
• 🤖 Multi-Model Support - OpenAI, Gemini, local models (hosted via vLLM etc)
• 🛠️ Tools and Skills System - File operations, web search, shell execution. Integrated Anthropic Skills and allow user self defined skills.
• 🔌 MCP Support - Model Context Protocol integration (currently integrated Context7)
• 🔒 Permission Control - Fine-grained permission requests and access control
• 💬 Session Management - Project-level and global session storage
• 🎯 Background Tasks - Create, track, and manage background tasks.
• 📜 Constitutional AI - Customizable behavioral guidelines

For OpenAI apis, currently up to GPT-5 is supported, while GPT-5.2 is not (due to planning is not currently supported yet), but will be added in future updates. The purpose of this project is to experiment with building a modular AI assistant that can integrate multiple models, and tools, with full control and transparency. Only use it for fun, not for production.
