Search for engineering items (BOM items) in the vault.
AI agents call vault_search_items to retrieve information from Vault MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and searches for existing data without modifying, deleting, or executing operations. It performs a query against the Vault database and returns matching results. No side effects or state changes occur. This is a classic Read category operation with low risk of misuse—the worst outcome is unauthorized information disclosure of items already in the system.
From the tool's definition Tool name 'vault_search_items' and description 'Search for engineering items (BOM items) in the vault' indicate a query/search operation.
