WHAT IT DOES

What noaa-ncei-list-datasets does on Meta Data Mcp

AI agents call noaa-ncei-list-datasets to retrieve information from Meta Data Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why noaa-ncei-list-datasets is rated Low

This tool queries and returns a list of available datasets from NOAA's National Centers for Environmental Information. It performs a read-only discovery operation with no capacity to modify, delete, or execute operations. The blast radius of misuse is minimal — at worst, an agent could enumerate datasets, which is non-damaging information retrieval.

From the tool's definition Tool name contains 'list' and description states 'List NCEI datasets discoverable via the search service' — a retrieval operation with no side effects.
