MCP Server to run python code locally

Catalog onlyCatalog onlySTDIO

Overview

The python_local MCP Server is an interactive environment that allows users to run Python code locally, providing a Read-Eval-Print Loop (REPL) experience.

To use the server, configure it following the installation instructions, and then access the REPL through the provided custom URI scheme to start executing Python code.

  • Provides a persistent REPL for Python code execution - Maintains separate session states and supports multiple sessions simultaneously - Offers full access to execution history via a text/plain resource - Captures and returns both standard and error outputs from the executed code
  1. Rapidly testing Python code snippets in an interactive environment
  2. Debugging code by accessing previous sessions and outputs
  3. Learning Python through a hands-on coding approach in a local setup

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "python-mcp-alec2435": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-python-mcp-alec2435"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "python-mcp-alec2435": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-python-mcp-alec2435"
      ]
    }
  }
}

Claude Code

Add this to your project's .mcp.json file. Claude Code will detect it automatically.

.mcp.json (project root)

{
  "mcpServers": {
    "python-mcp-alec2435": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-python-mcp-alec2435"
      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{
  "servers": {
    "python-mcp-alec2435": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-python-mcp-alec2435"
      ]
    }
  }
}

Windsurf

Add this to your Windsurf MCP config file, then restart Windsurf.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "python-mcp-alec2435": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-python-mcp-alec2435"
      ]
    }
  }
}

Cline

Open Cline settings, navigate to MCP Servers, and add this server configuration.

Cline MCP Settings (via UI)

{
