Security profile

Claimed and verified servers get a weekly static scan that shows what the code can reach: external services, environment variables, shell commands, agent configuration folders, plus any dependencies with known advisories. Claim this listing to get one. How the security profile works

Documented tools (3)

From project documentation. A server handshake does not verify each tool’s description or behavior.

lookup_object

Look up a celestial object by Messier number, NGC/IC designation, or common name. Optionally compute visibility from a given location and time.

plan_session

Generate an observing session plan for a given location and date. Returns the best objects to observe grouped by time window.

search_objects

Search and filter the catalog by type, constellation, magnitude range, angular size, or catalog membership.
