iFlytek Workflow MCP Server is a simple MCP server implementation built to call iFlytek workflows via MCP tools. It enables intelligent workflow scheduling and execution, combining a structured workflow model with real-time data flow. The workflow is composed of multiple nodes and supports 14 node types (including basic, tool, logic, and transformation). By default, a workflow includes a Start Node (user input) and an End Node (output result). When triggered, workflows execute automatically according to predefined sequences and rules, requiring no manual intervention. Core capabilities include robust node support with complex variable I/O, and advanced orchestration modes such as sequential, parallel, loop, and nested execution, together with a Hook mechanism that enables streaming output for real-time processing. The system supports multiple development paradigms—single-turn, single-branch; single-turn, multi-branch; single-turn loop; and multi-turn interaction with context memory—providing flexibility for various use cases. For capability expansion, the platform offers Multi-Model Support based on the Model of Models (MoM) architecture, allowing flexible model choices at critical workflow stages. Usage involves MCP client integration, preparing a config.yaml, obtaining authentication, and publishing workflows as API.
