Answer
Secure agents by securing tools: auth, permissions, audit logs, and strict separation of secrets from prompts. Prefer a gateway/tool-server boundary (e.g., MCP servers) so the model never gets direct credentials. Dedalus provides an MCP gateway and can host MCP servers.
Nuances & Considerations
The main risks are unauthorized actions and data exfiltration via tool outputs; mitigate with least privilege and logging.
