Container Use vs Python Exec Sandbox
A side-by-side look at the Container Use and Python Exec Sandbox MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Container Use for code execution work; choose Python Exec Sandbox for code execution as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Container Use when
- You need dedicated capabilities in the Code Execution domain.
- Its auth model fits you: No auth required.
Choose Python Exec Sandbox when
- You need dedicated capabilities in the Code Execution domain.
- You prefer a local stdio subprocess transport.
- You want tools like
execute_python, check_environment, validate_script.

Python Exec Sandbox tools 3
execute_pythonExecute a Python script with automatic dependency management. The script can include PEP 723 inline metadata (# /// script blocks) for declaring dependencies. Additional dependencies can also be passed via the dependencies parameter and will be merged. Args: script: Python source code to execute. May include PEP 723 metadata. dependencies: Extra PEP 508 dependency specifiers to make available. timeout_seconds: Maximum execution time (1-300, default 30). Returns: Formatted output with stdout, stderr, exit code, and duration. Example - simple script: execute_python(script="print('hello')") Example - with dependencies parameter: execute_python( script="import requests; print(requests.get('https://example.com').status_code)", dependencies=["requests>=2.32"] ) Example - with inline dependency metadata (preferred for multiple deps): execute_python(script=''' # /// script # dependencies = ["pandas>=2.2", "numpy>=1.26"] # /// import pandas as pd import numpy as np print(pd.DataFrame({"a": np.arange(5)}).describe()) ''') Always pin dependency versions (e.g. "pandas>=2.2" instead of "pandas") for reproducible results. The inline metadata block (# /// script ... # ///) is the recommended way to declare dependencies directly in the script (see PEP 723: https://peps.python.org/pep-0723/). The dependencies parameter is a simpler alternative when you just need to add a few packages. Both accept standard pip-style version specifiers like "requests>=2.28" or "pandas" (see PEP 508: https://peps.python.org/pep-0508/).check_environmentCheck the execution environment and report status. Returns information about Python version, uv version, platform, sandbox configuration, and cache status.validate_scriptValidate a Python script's PEP 723 metadata and dependencies without executing it. Checks metadata syntax, dependency format, and requires-python compatibility. Args: script: Python source code to validate. May include inline dependency metadata (# /// script blocks, see https://peps.python.org/pep-0723/). dependencies: Extra dependency specifiers to validate, using standard pip-style format like "requests>=2.28" (see https://peps.python.org/pep-0508/). Returns: Validation result with metadata details or error information.
Ready-to-paste client configs
Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
Container Use
No confirmed install command for Container Use yet — follow the setup steps linked from its listing page rather than a guessed package name.

Frequently asked questions
Container Use is categorized under Code Execution and uses an install path we have not confirmed yet. Python Exec Sandbox belongs to Code Execution and uses a local stdio subprocess. Pick Container Use for code execution work and Python Exec Sandbox for code execution.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client. Container Use has no confirmed install command yet — follow its own setup instructions.
Container Use is listed as free. Auth: no auth required. Python Exec Sandbox has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add dagger-container-use and python-exec-sandbox as separate keys in the same mcpServers object, and your assistant will call tools from either one.
On AllMCPs, Container Use has a quality signal of 51/100 (Good) with 3 views, 0 installs and 4,078 GitHub stars. Python Exec Sandbox has 52/100 (Good) with 2 views, 0 installs and 1 GitHub stars.
