Original Pull Request: https://github.com/langgenius/dify/pull/27016

State: open
Merged: No

Summary

We have deployed a set of Dify on our internal network. To access the internet from the office intranet, we need to go through an HTTP proxy. Currently, the MCP client of Dify does not support proxy configuration, which prevents us from using the MCP server on the internet with Dify on our internal network.

Close #26989

  1. Frontend: Add proxy configuration items on the MCP configuration page, including proxy host, account, and password.
  2. Backend: Modify the API to add and get proxy configuration, and save the app-level proxy configuration encrypted in the database; include the proxy information when sending requests from the MCP client.
  3. Database: Modify the MCP table structure to add a proxy field.
  4. Configuration File: Add an MCP proxy switch to allow users who do not need this feature to disable it globally during deployment.
