mysql_mcp_server

The `call_tool` function directly executes arbitrary SQL queries provided by the AI assistant (`cursor.execute(query)`). This is a critical SQL injection vulnerability if the AI's output is not strictly controlled or whitelisted. While the documentation explicitly warns about this and recommends 'query whitelisting for production use' and using a 'database user with minimal required permissions', the server itself exposes this high-risk functionality. The `read_resource` function dynamically constructs table names from the URI (`f"SELECT * FROM {table} LIMIT 100"`), which is also a potential, albeit lower, SQL injection risk if URI parsing is insufficient or an attacker can craft malicious URIs. No hardcoded secrets were found, and configuration uses environment variables, which is a good practice.
