keyword_search
AI agents call keyword_search to retrieve information from DigiKey MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a search query to retrieve product information from the DigiKey catalog. It has no side effects—it does not create, modify, delete, execute code, or commit financial transactions. The sibling tools like 'product_details' and 'search_manufacturers' further confirm this is a data retrieval API.
From the tool's definition Tool name 'keyword_search' combined with server context stating it 'allows users to search for electronic components and retrieve detailed product specifications' and supports 'keyword searches' indicates a read-only retrieval operation.
