WHAT IT DOES

What mittwald_container_run does on Mittwald MCP Server

AI agents invoke mittwald_container_run to trigger actions in Mittwald MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why mittwald_container_run is rated High

Creating and starting a container is a direct code execution primitive. An AI agent given this tool can run arbitrary workloads, install software, access host resources, exfiltrate data, or pivot to other systems — depending entirely on what container image and entrypoint arguments are provided.

From the tool's definition Tool description states 'Create and start a new container' — this launches arbitrary containerized code execution.
