 This server exposes one key resource: "memo://insights", which is a business insights memo that gets automatically updated throughout the analysis process. As users analyze the database and discover insights, the memo resource gets updated in real-time to reflect new findings. Resources act as living documents that provide context to the conversation.
 Tools:
 This server provides several SQL-related tools:
-"read-query": Executes SELECT queries to read data from the database
-"write-query": Executes INSERT, UPDATE, or DELETE queries to modify data
-"create-table": Creates new tables in the database
-"list-tables": Shows all existing tables
-"describe-table": Shows the schema for a specific table
-"append-insight": Adds a new business insight to the memo resource
+"read_query": Executes SELECT queries to read data from the database
+"write_query": Executes INSERT, UPDATE, or DELETE queries to modify data
+"create_table": Creates new tables in the database
+"list_tables": Shows all existing tables
+"describe_table": Shows the schema for a specific table
