td_list_tables
AI agents call td_list_tables to retrieve information from Treasure Data MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list_' prefix and contextual pattern from sibling tools strongly suggest this retrieves table metadata without modifying data. No description is provided, which slightly lowers confidence, but the naming convention and server purpose (retrieve database information) indicate a non-destructive query operation.
From the tool's definition Tool name 'td_list_tables' with prefix 'list_' indicates a retrieval operation. Sibling tools like 'td_list_databases', 'td_list_projects', 'td_list_workflows' establish a pattern of read-only listing operations on this MCP server.
