Search for cities by name and return matching results as text with outputSchema
AI agents call searchCitiesText to retrieve information from Weather 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 city information based on name input. It returns data (as text) with no side effects, data modification, or irreversible actions. This is a straightforward read operation with minimal risk if misused by an AI agent—worst case would be retrieving unwanted city data or excessive queries.
