php-mcp-server

The server demonstrates good practices for JSON-RPC parsing by using JSON_THROW_ON_ERROR and includes explicit checks for property existence and type validation for incoming parameters. It uses a PSR-3 Logger for debugging/error logging, and custom exception handling. The default HTTP binding is to localhost (127.0.0.1), limiting network exposure. No direct 'eval' or 'shell_exec' are present. The primary security consideration for a system like this, not directly visible in the provided code, would be how tools and prompts are registered. If the registration process were exposed to untrusted input, it could lead to arbitrary code execution via the 'handler' callables. However, based on the provided code, registration happens programmatically within the application code, not through user-controlled input.
