Get U.S. weather forecasts, alerts, and current observations via NWS API.
This MCP tool is described as providing weather forecasts, alerts, and observations via the U.S. National Weather Service API. It is open-source and requires no credentials, so overall risk appears low, but as an executable MCP tool it still warrants caution around local execution and actual network behavior. Confidence is limited by the missing README, low community adoption, and unknown maintenance status.
The materials explicitly state that no keys or environment variables are required. There is no indication that account credentials, API tokens, or other sensitive authentication data are needed, so credential exposure and misuse risk appears low.
The description indicates it retrieves weather data via the U.S. National Weather Service API, which is normal outbound access consistent with its stated purpose. However, the materials do not list specific hostnames and the README is absent, so the full request scope and whether any additional egress endpoints exist cannot be verified here.
System checks indicate that this tool executes code. That is a common capability for MCP services and does not by itself imply high risk. The available materials do not show requests for unusual system privileges or clearly unrelated high-risk operations.
The materials only describe weather forecasts, alerts, and observations, with no stated need to read local files, write to disk, or access contacts, browser data, or other sensitive local resources. No clear sign of overbroad data access is present.
Positive factors include that the project is open-source, auditable, and Apache 2.0 licensed. However, it comes from a third-party registry, has 0 GitHub stars, unknown maintenance status, and no README in the provided materials, which reduces confidence in implementation quality and ongoing upkeep.
