HarnessAPI: A Python Framework for Unified Streaming APIs and MCP Tools
HarnessAPI is an innovative Python framework designed to streamline the deployment of Python functions for large language model applications. It addresses the common challenge of code duplication by centralizing multiple functionalities into a single typed skill folder. This approach facilitates the automatic generation of a streaming HTTP endpoint using Server-Sent Events, along with a user-friendly OpenAPI/Swagger interface and a simplified management tool. Developers can effectively cater to both SSE and JSON clients without additional setup. For more details, the relevant research can be accessed on arXiv with the identifier 2605.22733.
