AgentSUMO runs on your own machine — the client starts it, so there is no endpoint to ping. 143 installs a week from pypi. Last commit 17 Jun 2026.
MCP server for LLM-driven SUMO traffic simulation, scenario design, and result analysis.

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
result = subprocess.run(cmd, capture_output=True, text=True)
return os.path.join(cls.SUMO_HOME, "share", "sumo", "tools", tool_name)
container.innerHTML = renderTree(data.tree);

This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
