Current position of any cataloged satellite by NORAD number (e.g. 25544=ISS) via fresh Celestrak elements + SGP4. Returns sub-point lat/lon/altitude + speed; pass observer lat/lon for azimuth/elevation/range look angles.
AI agents call space.satellite to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves current satellite position information from Celestrak elements using SGP4 calculations. It is a read-only query that returns positional data and look angles based on input parameters. There are no side effects, data modifications, code execution, or financial implications. The tool has legitimate public astronomical and tracking uses.
From the tool's definition Tool description states 'Returns sub-point lat/lon/altitude + speed' and 'pass observer lat/lon for azimuth/elevation/range look angles' — purely retrieves and queries satellite position data with no modification or side effects.
Attacks that exploit this kind of access
Current position of any cataloged satellite by NORAD number (e.g. 25544=ISS) via fresh Celestrak elements + SGP4. Returns sub-point lat/lon/altitude + speed; pass observer lat/lon for azimuth/elevation/range look angles. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for space.satellite: 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 Mcp. Nothing to install.
space.satellite 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 space.satellite 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 space.satellite. 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.
space.satellite is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
