Fetch the latest Two-Line Element set for a satellite by NORAD ID.
AI agents call tle_lookup to retrieve information from Spacetrack without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a public space catalog database to retrieve orbital element data for a satellite. The operation is read-only, returns informational data, and has no capability to modify, delete, or execute arbitrary operations. The potential for misuse is minimal—an agent with this tool can only fetch existing TLE data, which is publicly available information about satellite orbits.
From the tool's definition Tool name 'tle_lookup' and description 'Fetch the latest Two-Line Element set for a satellite by NORAD ID' indicate a query operation that retrieves data with no modifications or side effects.
Attacks that exploit this kind of access
Fetch the latest Two-Line Element set for a satellite by NORAD ID. It is categorised as a Read tool in the Spacetrack MCP Server, which means it retrieves data without modifying state.
Register the Spacetrack MCP server in PolicyLayer and add a rule for tle_lookup: 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 Spacetrack. Nothing to install.
tle_lookup 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 tle_lookup 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 tle_lookup. 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.
tle_lookup is provided by the Spacetrack MCP server (kaushik701/spacetrack-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
