WhatsApp-AI-Bot

The application employs environment variables for sensitive data like API keys and verification tokens, which is a good practice. User input (message text) is escaped before being included in JSON payloads, mitigating potential JSON injection risks when communicating with the Meta WhatsApp API. Webhook verification ensures authenticity of incoming requests. The architecture's separation into a main bot service and a distinct MCP server for tools enhances modularity and potentially reduces the attack surface. No direct 'eval' or easily exploitable code injection vulnerabilities are apparent in the provided source code. Primary security considerations would revolve around prompt injection for the LLM and the secure management of API keys and server exposure during deployment.
