请问这个错误是因为什么
这是我的配置，用的官方的平台

Solution

1. Update to latest version of this plugin (v0.0.4)
2. Read warning of https://github.com/3dify-project/dify-mcp-client#config
   🔍 You are trying to awake stdio mcp server.
   ⚠️ Stdio server is only supported source code deploy. at README.md
   The .difypkg doesn't work because module PATH (like npx) is unavailable in the built-in Python environment. #1

Please convert stdio MCP server to SSE MCP server. How to convert?

I have already update to 0.0.4,but still get this error, also I use amap as you do in the example, it's so confused

[meme-dayo]

A stdio server's awaking command like uvx is unavailable, unless you deploy this plugin by source code without ".difypkg or GitHub URL install".

Why don't you convert MCP server from stdio to SSE?

Tip

SSE only has "url:" key in config.json.

I'm using MCP server of amap, I followed this video and it worked
Maybe it's something with the diffy version? And I'm using the diffy platform provided by offical, maybe I should launch a studio2SSE server on public host?

[meme-dayo]

This method is what I want! Thank you for give me the video URL.

💡I found you don't need to convet into SSE with such a Dockerfile and image container.

• tangyoha/dify-plugin Docker image has Node.js inside it.
• Subprocess launched by dify plugin inside docker knows path for Node.js.

Tell me your steps when "it worked".

Q1. Which version of dify-mcp-client plugin did you use ? (v0.0.3 or v0.0.4)

Q2. Did you skip 2.1~2.2 of following URL?

• 2.1 创建 Dockerfile
• 2.2 构建镜像

https://github.com/tangyoha/tangyoha-bili/tree/master/dify/mcp/map_mcp#21-%E5%88%9B%E5%BB%BA-dockerfile
tangyoha/dify-plugin:latest updated 2 weeks ago, so its .difypkg and dify-plugin-daemon is not latest.

Try this solution

2.1 Fix Dockerfile

# 使用指定的基础镜像
- FROM langgenius/dify-plugin-daemon:0.0.6-local
+ FROM langgenius/dify-plugin-daemon:0.0.7-local

2.2 Build docker image

docker build -t dify-plugin:latest .

Warning

Skip 2.3 或者直接使用我构建好的镜像
Use v0.0.4+ dify-mcp-plugin https://github.com/3dify-project/dify-mcp-client/releases

thank you very much, it's exactly the promblem of the env, I used offical dify platform as I mentioned, and now I build my own env followed the instruction and it worked, brilliant work!

[IQTvoai]

I use dify v1.7.0 official with dify-mcp-client v0.0.6 get same error
