AI agents call get_group to retrieve information from Mcp Celestrak without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

group | string | Yes | A CelesTrak group, e.g. "stations", "starlink", "gps-ops", "weather", "science", "geo", "active". |
Parameters from the server's own tool schema.
This tool retrieves and queries publicly available satellite orbital catalog data (TLE/GP elements). It has no side effects, does not modify state, execute code, delete data, or commit financial transactions. It is a straightforward read operation that returns static catalog information about tracked satellites in predefined groups.
From the tool's definition Tool description explicitly states it 'List orbital elements' and 'Returns up to 100 satellites with orbital parameters'.

List orbital elements (TLE / GP data) for an entire CelesTrak group — e.g. the Starlink, GPS, or weather satellite catalog. Groups: "stations", "starlink", "gps-ops", "weather", "science", "geo", "active". Returns up to 100 satellites with orbital parameters (inclination, eccentricity, period). Catalog/orbital data, not live tracking. It is categorised as a Read tool in the Mcp Celestrak MCP Server, which means it retrieves data without modifying state.
get_group accepts 1 parameter: group. Required: group. The full parameter table on this page comes from the server's own tool schema.
Register the Mcp Celestrak MCP server in PolicyLayer and add a rule for get_group: 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 Celestrak. Nothing to install.
get_group 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_group 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_group. 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_group is provided by the Mcp Celestrak MCP server (pipeworx-io/mcp-celestrak). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
