get_language_literacy
AI agents call get_language_literacy 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 strongly suggests querying language literacy statistics—a read operation with no side effects. The server context (thematic layers, population statistics, public transport data) confirms this is a data retrieval system. Empty description lowers confidence slightly, but the naming pattern and sibling tools (all read-only getters) support Read classification.
