MCPWorks is an open-source AI agent runtime built on the Model Context Protocol (MCP) that enables developers to deploy persistent, autonomous agents running 24/7 in isolated containers with scheduling, webhooks, encrypted state, and communication channels. The platform uses code-mode execution in nsjail sandboxes to reduce LLM token consumption by 70–98% compared to standard MCP, and is available as a free self-hosted edition (BSL 1.1) or a managed cloud service.
