AI agents call nasa_osdr_files to retrieve information from Nasa without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries existing data files from NASA's Open Science Data Repository without modifying, deleting, or executing any operations. The 'Get' action is a standard read operation with no side effects. Severity is low because the data is from a public repository and retrieval poses minimal risk.
From the tool's definition Tool name and description indicate data retrieval: 'Get data files for an OSD study' uses the verb 'Get', which is a read operation. OSDR (Open Science Data Repository) is a public data archive.
Attacks that exploit this kind of access
NASA OSDR - Get data files for an OSD study. It is categorised as a Read tool in the Nasa MCP Server, which means it retrieves data without modifying state.
Register the Nasa MCP server in PolicyLayer and add a rule for nasa_osdr_files: 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 Nasa. Nothing to install.
nasa_osdr_files 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_osdr_files 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_osdr_files. 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.
nasa_osdr_files is provided by the Nasa MCP server (@programcomputer/nasa-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
