Tool-level sandboxing for RAG agents - governance and isolation

Where this came from

Bluesky

The RAG use case is the perfect example of where agent infrastructure needs governance. Simply connecting to a database isn't enough; you need secure sandboxing for the *tools* the LLM calls (e.g., 'execute query,' 'validate schema'). Vinkius handles that tool-level isolation layer.

The pain

RAG and agent workflows expose tools as attack surfaces. Provide per-tool sandboxing, permissioning, and audit logs so LLMs can safely call execute-query and other actions without leaking data or breaking compliance.

Who it is for

Engineering and platform teams building RAG/agent applications in regulated or risk-sensitive environments, plus security/compliance teams responsible for data access governance.

Source pains

• LLM agents calling database or executor tools can exfiltrate sensitive data because connection-level controls are insufficient.
• Teams lack per-tool isolation and fine-grained permissioning for agent-invoked actions like execute query or write-back, creating compliance and ops risk.
