A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

        await fs.writeFile(out, bytes);

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.

This one needs environment variables set before it will start: PUMPFUN_MCP_URL (Override the canonical pump.fun MCP backend endpoint. Defaults to https://three.ws/api/pump-fun-mcp — set this only when self-hosting the handler.). The author declared them in the registry entry; get the values from the project itself.
