The `handle_calculator` function uses `eval()`, which is an inherent security risk. While an empty `__builtins__` dictionary is passed to `eval`, it does not fully mitigate all potential code injection vectors, especially if the input expression is crafted maliciously. The `handle_file_read` and `handle_file_write` functions directly use the `path` parameter provided by the agent. This introduces a critical path traversal vulnerability, allowing an attacker to read from or write to arbitrary files on the system that the server process has permissions for. This could lead to information disclosure, data corruption, or arbitrary code execution by overwriting critical system files or injecting malicious scripts.
