  The MCP tool handler for 'list_tables', decorated with @mcp.tool(). It retrieves the list of tables from the MochowConnector and formats them into a string response.

  @mcp.tool()
  async def list_tables(ctx: Context) -> str:
      """
      List all tables in the current database.
  
      Returns:
          str: A string containing the names of all tables.
      """
      connector = ctx.request_context.lifespan_context.connector
      tables = await connector.list_tables()
      return f"Tables in database:\n{', '.join(tables)}"

• src/mochow_mcp_server/server.py:104-117 (helper)

  Helper method in MochowConnector class that lists all tables in the current database using the Mochow database client and returns a list of table names.

      Returns:
          list[str]: A list of table names.
      """
      if self.database is None:
          raise ValueError("Switch to the database before list tables")
      try:
          tables = self.database.list_table()
          return [table.table_name for table in tables]
      except Exception as e:
          raise ValueError(f"Failed to list tables: {str(e)}")
