PRIMS Python Sandbox MCP server

PRIMS is a small helper that gives your AI the ability to actually run Python code, not just talk about it. You ask for something, the AI writes the code, runs it in a fresh sandbox, and shows you what came out. It is handy if you work with data, spreadsheets, or small calculations and want answers without installing anything yourself.

What this MCP server does

You ask your AI to do something that needs code, like reading a CSV file or making a chart. The AI writes the Python, then hands it to this helper. The helper starts a clean, temporary workspace, installs any packages the code needs, and runs it. When it finishes, it sends back whatever the code printed, plus any files it created. Then the workspace is wiped, so nothing lingers.

What you can do with it

• Run Python code you or the AI wrote, in a safe temporary sandbox
• Install extra Python packages on the fly for a single run
• Read a CSV or other file you point it to and work with the data
• List the files your code created in the session workspace
• Preview the first part of a text file to check the result
• Save a generated file (like a chart) to a permanent location
• Download a remote file once and reuse it during the session

Try asking your AI

• “Read this CSV file and tell me the average of the sales column”
• “Make a bar chart of these numbers and save it as a PNG”
• “Write a small Python script that cleans up this list of names and run it”
• “Install pandas and show me the first five rows of this dataset”

What it gives back to you

You get back whatever the code printed, plus any error messages if something went wrong. If the code created files, like a chart or a cleaned CSV, you can preview or download them. The AI usually summarizes the result in the chat too, so you do not have to read raw output.

Before you start

Who it's for

Anyone who wants their AI to run small Python tasks for them, like analysts, students, or office workers handling data, without setting up a coding environment themselves.
