How to Use the Trefle MCP in Claude

Q: How do I check plant distributions using Trefle and Claude Desktop?

You call getdistributionplants and pass the filter parameters. This tells your agent to look up plants by a specific establishment, like 'native.' The results show you which species are present in that zone.

Q: What if I find an error? How do I report it using Trefle and Claude Desktop?

If your research uncovers bad data, use the reportspecieserror tool. This sends a structured complaint about species information directly back into the database for correction.

Yes. Just use the listplants tool. It provides a clean list of the primary, recognized plant species, excluding minor forms or varieties.

Perplexity

Pinpoint Plant Locations

You run `get_distribution_plants` and filter by establishment using query parameters. This shows you exactly which plants exist in a specific zone, like filtering for only 'native' species. Need to know where things grow? Use `list_distributions` first to see all available zones. Then, narrow down the list with targeted calls to find your exact location data.

Detailed Species Lookup

Get full details on a specific plant using `get_plant`, or dive deeper by calling `get_species` for comprehensive sub-taxa information. This gives you the whole picture, from genus to variety. When general searching isn't enough, use `search_plants` to query main species names. You also have dedicated tools like `report_species_error` if you spot bad data.

Manage Botanical Data

Want a master list of available genera? Just call `list_genera` to see them all at once. Similarly, use `list_plants` when you need the primary species names without getting bogged down in varieties or subspecies. Curious about what's available? `search_species` lets your agent search through every type of species name, making it easy to find anything you’re looking for.
