Get real-time solar wind data including speed, density, temperature, and magnetic field components (Bx, By, Bz, Bt). Negative Bz values indicate southward IMF which can trigger geomagnetic storms.
AI agents call get_solar_wind to retrieve information from NOAA Space Weather MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward data retrieval tool that queries NOAA space weather APIs and returns observational measurements. The tool has no destructive capability, does not modify state, does not execute arbitrary code or commands, and does not involve financial operations. The analytical interpretation of Bz values for geomagnetic storm prediction is informational only and does not affect system state.
From the tool's definition Tool retrieves real-time solar wind data (speed, density, temperature, magnetic field components) with no modification capability or side effects.
Attacks that exploit this kind of access
Get real-time solar wind data including speed, density, temperature, and magnetic field components (Bx, By, Bz, Bt). Negative Bz values indicate southward IMF which can trigger geomagnetic storms. It is categorised as a Read tool in the NOAA Space Weather MCP Server MCP Server, which means it retrieves data without modifying state.
Register the NOAA Space Weather MCP Server MCP server in PolicyLayer and add a rule for get_solar_wind: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches NOAA Space Weather MCP Server. Nothing to install.
get_solar_wind is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_solar_wind rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_solar_wind. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_solar_wind is provided by the NOAA Space Weather MCP Server MCP server (numa08/noaa-space-weather-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
