iNaturalist
api.inaturalist.org
Community wildlife observations and taxonomy: what was seen, where, when and by whom.
The crw MCP on your computer calls iNaturalist directly. Calls cost no credits and the data does not pass through fastCRW. Install it once for Claude Code, Cursor, Codex, Windsurf, Gemini CLI or OpenCode, with your fastCRW API key in place of the placeholder:
Ask with this source
A prompt for your agent that names this source and how to call it through the crw MCP.
Annotation vocabulary
Use iNaturalist (inaturalist) from fastCRW Pergamon, capability "Annotation vocabulary" (controlled-terms). You need the term_id and term_value_id numbers before you can filter observations by an annotation, or you are decoding annotations in a response. Example options: locale=en. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "inaturalist" and capability "controlled-terms". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
Annotations for a taxon
Use iNaturalist (inaturalist) from fastCRW Pergamon, capability "Annotations for a taxon" (controlled-terms-for-taxon). You are about to annotate or filter one specific organism and need to know which traits iNaturalist actually records for it. Example options: taxon_id=1, locale=en. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "inaturalist" and capability "controlled-terms-for-taxon". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
Identification details
Use iNaturalist (inaturalist) from fastCRW Pergamon, capability "Identification details" (identification-details). You have an identification id from a search or a webhook and need the whole context behind that single determination. Example options: id=910099310. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "inaturalist" and capability "identification-details". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
Identification search
Use iNaturalist (inaturalist) from fastCRW Pergamon, capability "Identification search" (identifications). You are auditing how a determination was reached or tracking one identifier's activity, rather than looking at observations. Example options: q=juvenile, taxon_id=47219, observation_taxon_id=47219. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "inaturalist" and capability "identifications". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
