}
Environment variables
  • UMBRA_CANOPY_TOKENsecretCanopy API token. Set it and the same search tools query Umbra's authenticated commercial archive instead of the open bucket; leave it unset for the open data, which needs no credentials.
  • ANTHROPIC_API_KEYsecretOptional. With a key, describe_scene and narrate_change call a vision model on the server. Without one they return a reading kit (picture + SAR primer) so the client's own model does the reading. A public host must not set this.
  • OPENAI_API_KEYsecretAlternative provider for the same two model tools, and the encoder behind find_similar_text.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
