Problems Solved
- Keep user identity out of model-controlled tool inputs
- Share a database or service handle across all tools
- Scope tool execution to the authenticated request
- Prevent prompt-injection from accessing other users' data
Use Cases
- Per-user account assistants
- Multi-tenant agent tools
- Injecting DB/session into isolated tool calls
- Secure identity scoping for agent tools
