Dify MCP Client

Example Use Cases

• 1

  Call external MCP servers (SSE or Streamable HTTP) to access custom tools and resources during ReAct-style reasoning loops.

• 2

  On-demand GUI automation integrated into workflows using UI-TARS (e.g., automating UI actions from an LLM agent with lifecycle limits).

• 3

  Convert existing Tool/Resource/Prompt definitions into Dify tools so an LLM can invoke them seamlessly inside Dify chatflows and workflows.

Description

This repository implements an MCP client plugin for the Dify platform that allows agent strategy nodes (ReAct agents) to connect to one or more MCP servers and invoke tools/resources as Dify tools. It supports multiple transports including SSE and Streamable HTTP, provides a UI-TARS SDK integration for on-demand GUI automation, and includes Docker deployment guidance and examples. The plugin converts Tool, Resource, and Prompt lists into Dify Tools so LLM-driven agents can Reason → Act → Observe using external MCP services. The README also includes development and packaging instructions and cautions about using reliable MCP servers and lifecycle limits for automation.
