check_theme_status
AI agents call check_theme_status to retrieve information from OneMap MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name indicates a status check operation, which is a read-only query. The OneMap server context shows it provides data access for location searches, routing, and statistical information. A theme status check would retrieve information about available thematic layers without modifying or executing operations.
From the tool's definition Tool name 'check_theme_status' combined with server context showing thematic layers and data access functions suggests a status query operation. Description is empty, reducing confidence slightly.
