Offline observational astronomy: positions, rise/set, moon phases, eclipses, and seasons.

Trust verdict · v1 advisory · method
NOT YET SCREENEDno verdict on file

Verdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits.

Environment variables
MCP_LOG_LEVEL

Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').

ASTRONOMY_ENABLE_HORIZONS

Register the astronomy_get_ephemeris tool, which fetches small-body and spacecraft ephemerides from JPL Horizons. Off by default; the core is keyless and offline.

ASTRONOMY_ENABLE_SATELLITES

Register the astronomy_get_satellite_passes tool, which predicts visible satellite passes from CelesTrak TLEs propagated with SGP4. Off by default.

ASTRONOMY_DEFAULT_TIMEZONE

Fallback IANA timezone for observer-local output when a tool call omits `timezone`. Unset means UTC-only output.

MCP_HTTP_HOST

The hostname for the HTTP server.

MCP_HTTP_PORT

The port to run the HTTP server on.

MCP_HTTP_ENDPOINT_PATH

The endpoint path for the MCP server.

MCP_AUTH_MODE

Authentication mode to use: 'none', 'jwt', or 'oauth'.

MCP_LOG_LEVEL

Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').
