Get space weather events from NASA DONKI (Database Of Notifications, Knowledge, Information)
AI agents call nasa_donki_space_weather to retrieve information from MCP TypeScript NASA Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a read-only database to fetch space weather event information. It has no side effects, does not modify data, does not execute code or commands, and does not involve financial transactions. It is purely informational retrieval, consistent with other sibling tools on this server (apod, earth imagery, mars rover photos) which are all Read category tools accessing NASA's public data APIs.
From the tool's definition Tool retrieves space weather events from NASA's DONKI database. The description contains no language indicating mutation, deletion, execution, or financial operations. Terms like 'Get' and 'from' indicate data retrieval only.

Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP TypeScript NASA Server. Nothing to install.
nasa_donki_space_weather 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 nasa_donki_space_weather 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 nasa_donki_space_weather. 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.
