Daytona MCP Python Interpreter

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

Installation+

Install uv if you haven’t already:


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

Create and activate virtual environment.

If by any case you have existing env, you should deactivate and remove the virtual environment:


deactivate
rm -rf .venv

Create and activate virtual environment:


uv venv
source .venv/bin/activate

(On Windows: .venv\Scripts\activate)

Install dependencies:


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

Development

Run the server directly:


uv run src/daytona_mcp_interpreter/server.py

Or if uv is not found (not in path):


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

NOTE. You can run which uv to get the path to uv.

You can use MCP Inspector to test the server:


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

Tail log:


tail -f /tmp/daytona-interpreter.log
