Which MCP Server Should You Choose?
G
Choose Guif when:
You need dedicated capabilities in the Developer Tools domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Search for species by common or scientific name. Returns matched taxa with rank, classification status, and taxonomic hierarchy. Use get_species with the taxon key for full details.
get_species
Get complete taxonomic classification for a species (kingdom through subspecies). Requires taxon key from search_species. Returns all ranks and accepted name status.
get_occurrences
Get georeferenced observation records for a species with coordinates, dates, and sources. Pass either `name` (a scientific name like "Danaus plexippus" — resolved automatically) or a numeric GBIF backbone `key`. Filter by country code (e.g., 'US', 'BR', 'AU') to narrow results geographically.
occurrences_near
Find species occurrence records NEAR a location (latitude/longitude + radius). PREFER for "what species/wildlife are found near here", "what birds/plants occur around these coordinates", "is <species> recorded near this spot". Optionally filter by a GBIF taxon key (from search_species) to a group o…
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Guif is categorized under Developer Tools and uses a remote streaming HTTP/SSE transport. In contrast, Worms belongs to Developer Tools using remote streaming HTTP/SSE transport. Select Guif when you need capabilities focused on developer tools and Worms when you require tools for developer tools.
Resolve a marine species or genus name to its WoRMS AphiaID, accepted name, authority, status (accepted/unaccepted), rank, and high-level classification (kingdom/family/genus). WoRMS is the authoritative world register of marine species. Keyless.
get_classification
Walk the full taxonomic lineage (root → tip) for a WoRMS AphiaID: returns a flat ordered array of { rank, name, aphia_id } from superdomain down to the taxon itself. Keyless.
get_common_names
Get common (vernacular) names for a WoRMS AphiaID across languages. Keyless.
