About AgentScope

AgentScope is an open-source framework for building and running AI agents with language models. It is published as a GitHub repository with Python code, documentation, and examples. The project focuses on making agent reasoning, tool calls, and outputs visible through a unified event system.

With it, developers can compose agents from building blocks such as a reasoning-acting loop, tool management for Python tools and MCP servers, and connections to models from several providers. It also provides context handling, memory backends, permission checks with human confirmation, and isolated execution in local or container-based sandboxes. Installation is via pip or from source, and requires Python 3.11 or higher.

AgentScope suits developers building Python-based agents who want to inspect behavior and manage tools, models, and multi-agent workflows.
