Validate a Bruno collection
AI agents call bruno_validate_collection to retrieve information from Bruno MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Validating a collection reads and checks its structure for correctness without modifying, deleting, or executing anything. This is a read/inspection operation with minimal blast radius.
From the tool's definition 'Validate a Bruno collection' — validation implies checking/reading structure without side effects
