Automated Agent Access Control for Enhanced Security

This n8n workflow, named "Agent Access Control Template," provides a robust solution for managing who can access what within your automated systems. Triggered by a Telegram message, it first queries an Airtable database to retrieve the requesting user's granted roles and specifically allowed tools. It then leverages Langchain's capabilities to communicate with OpenAI's GPT-4o model, maintaining session memory for context. Crucially, it dynamically checks the user's permissions against the tools they attempt to access. If a tool is not permitted for that user, it's replaced with a function that politely informs the user of their lack of authorization. This ensures granular control and prevents unauthorized access to sensitive functions or integrations.
