Server has 5 tools with basic descriptions and input schemas, but significant gaps in parameter documentation, output schema clarity, and error handling. Tool names follow verb_noun convention (get_, search_, list_) which is good. However, most parameters lack descriptions, e.g., search_datasets has 10 parameters but only 'erddap_url' and 'page' have descriptions; spatial/temporal filters are undescribed. Output schemas are not documented: tools return raw strings or lists without field definitions. No error handling guidance. Descriptions are present but generic (e.g., 'List all datasets in an ERDDAP server' appears twice). No validation of datetime formats, coordinate ranges, or pagination bounds. Overall pattern adherence is weak.

• Add descriptions to all parameters in search_datasets. For each spatial/temporal filter, specify format (e.g., 'min_longitude: float in range [-180, 180]'), units, and when to use it. Example: 'min_longitude: Minimum longitude for spatial filtering (float, range -180 to 180, optional).'
• Document output schemas for all tools. For list_datasets and list_dataset_variables, specify the CSV column names and types. For search_datasets, define the structure of returned dicts (e.g., 'Returns list of objects with fields: dataset_id (string), title (string), summary (string).').
• Add error handling with recovery guidance. Wrap external API calls in try-catch. Return structured errors like 'ERDDAP server unreachable at {erddap_url}. Verify the URL and try again.' instead of raw exceptions.
• Distinguish search_datasets from list_datasets in descriptions. Clarify: 'search_datasets: Filter datasets by query, standard name, or spatial/temporal bounds. Use this when looking for specific datasets.' 'list_datasets: Return all datasets without filtering. Use this for discovery or when you need the complete catalog.'
• Resolve the TODO in get_dataset_variable_data. Either detect the time variable name from dataset metadata, or add a 'time_variable_name' parameter with a default and clear description. Add validation to fail fast with a helpful error if the variable is not found.
