Search LinkedIn companies. Returns cleaned data in TOON format.
AI agents call search_companies to retrieve information from LinkedIn MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a search query to retrieve company information from LinkedIn. The verb 'search' and the fact that it 'returns' data (rather than modifying, deleting, or executing operations) clearly indicates a Read operation. There are no side effects, no data modification, and no external execution.
From the tool's definition Tool name 'search_companies' combined with description 'Search LinkedIn companies. Returns cleaned data in TOON format.' indicates a retrieval operation with no modification or deletion of data.
