What can you do with this server?

The Daytona MCP Python Interpreter enables AI assistants to execute code in secure, ephemeral sandboxed workspaces. With this server, you can: * Execute Python code and shell commands * Upload and download files with smart size management * Clone Git repositories (with branch selection and LFS support) * Generate web preview URLs for running servers * Integrate with AI assistants like Claude for code execution All operations occur in isolated environments that are automatically cleaned up after use.

How do I use Daytona MCP Python Interpreter?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Daytona MCP Python Interpreter run a Python script to calculate the average of these numbers: \[5, 10, 15, 20, 25]" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Daytona MCP Interpreter

A Model Context Protocol server that provides Python code execution capabilities in ephemeral Daytona sandboxes.

Daytona MCP Server in Claude Desktop

Overview

Daytona MCP Interpreter enables AI assistants like Claude to execute Python code and shell commands in secure, isolated environments. It implements the Model Context Protocol (MCP) standard to provide tools for:

Python code execution in sandboxed environments
Shell command execution
File management (upload/download)
Git repository cloning
Web preview generation for running servers

All execution happens in ephemeral Daytona workspaces that are automatically cleaned up after use.

Installation

Install uv if you haven't already:

curl -LsSf https://astral.sh/uv/install.sh | sh

Create and activate virtual environment.

If you have an existing env, deactivate and remove it first:

deactivate
rm -rf .venv

Create and activate a new virtual environment:

uv venv
source .venv/bin/activate

(On Windows: .venv\Scripts\activate)

Install dependencies:

uv add "mcp[cli]" pydantic python-dotenv "daytona-sdk>=0.10.5"

Note: This project requires daytona-sdk version 0.10.5 or higher. Earlier versions have incompatible FileSystem API.

Environment Variables

Configure these environment variables for proper operation:

MCP_DAYTONA_API_KEY: Required API key for Daytona authentication
MCP_DAYTONA_SERVER_URL: Server URL (default: https://app.daytona.io/api)
MCP_DAYTONA_TIMEOUT: Request timeout in seconds (default: 180.0)
MCP_DAYTONA_TARGET: Target region (default: eu)
MCP_VERIFY_SSL: Enable SSL verification (default: false)

Development

Run the server directly:

uv run src/daytona_mcp_interpreter/server.py

Or if uv is not in your path:

/Users/USER/.local/bin/uv run ~LOCATION/daytona-mcp-interpreter/src/daytona_mcp_interpreter/server.py

Use MCP Inspector to test the server:

npx @modelcontextprotocol/inspector \
  uv \
  --directory . \
  run \
  src/daytona_mcp_interpreter/server.py

View logs:

tail -f /tmp/daytona-interpreter.log
