list_dimensions
AI agents call list_dimensions to retrieve information from Northbeam MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or enumerates available dimensions within Northbeam's marketing analytics system. The empty description provides no evidence of side effects, and the naming pattern ('list_*') alongside sibling tools like 'get_attribution', 'get_channel_performance', and 'get_metric' all following retrieval patterns confirms this is a read-only query operation.
From the tool's definition Tool name 'list_dimensions' combined with server context describing 'querying of metrics, dimensions, channel performance, cohort analysis, and attribution data'. The 'list' prefix indicates data retrieval without modification.
