mcp-hello-world

The server implements a simple 'greet' tool with no external dependencies or dangerous operations, processing input locally. Communication is via standard I/O, typically for local process interaction. No 'eval' or hardcoded secrets were found in the server's code. The client (HelloWorldClient.kt) uses ProcessBuilder to launch the server JAR provided as a command-line argument; if the client were configured to accept untrusted input for this path, it could lead to arbitrary code execution, but this risk is on the client side, not within the server's logic itself.
