Safety Assessment

This MCP server offers a range of tools, including potentially destructive operations like deleting entities. While authentication is supported, the lack of sandboxing and direct database access necessitate careful configuration and usage. It is safe for read-only operations and collection listing, but risky when performing data deletion or modification without proper controls.

Authentication token support
Filter expressions for data operations
Collection management tools
SSE mode for multiple clients

Potential for data deletion via `milvus_delete_entities`
Direct access to Milvus database
Lack of explicit sandboxing
Environment variable based secret handling
