Feedback / Error of Example Prompts

[dilin-MS2]

Hi, I try out this amazing mcp server code runner.

• The first example question works well.
• The second one does not trigger the MCP server Code Runner to generate output. Are there any steps missing on my side?
• The 3rd example question gives wrong command in the beginning and manage to correct itslef later to get the corret answer.

Besides, there is error after loading this mcp server. Any idea how to fix it?

Thanks!

@GiganticRay Is your OS Windows? Do you run mcp-server-code-runner in local or remote? Does the path of python interpreter is set in PATH environment variable?

THX for replying, I am running mcp-server-code-runner locally on macos by using npm which outputs:

$ npm run start               

> mcp-server-code-runner@0.1.5 start
> node ./dist/index.js

Code Runner MCP Server running on stdio

here is my cheery studio mcp config:

@GiganticRay You may need to follow below doc to set path of python interpreter in PATH environment variable:
https://mac.install.guide/python/command-not-found-python
Let me know whether it works for you.

It does work! the reason is like the error msg, python could not be found.

1. install anaconda which rewrites my env PATH.
2. modify the env in cheery studio as PATH=/opt/anaconda3/bin

Good MCP Server. it is work well in my Cherry Studio on Windows 11. Thank you for making this amazing MCP Server.
tested with these prompts:

• Run the JavaScript Code: console.log(5+6)
• Where is temporary folder in my OS? Use run-code tool
• How many CPUs do I have in my machine? Use run-code tool

and tested using Python and JS. My python is manage by pyenv and node by nvm-windows.
