Is inaturalist-mcp-server live?

Yes — it answered the hub's last check (checked 36m ago). It answered 99% of checks over the last 30 days.

Is inaturalist-mcp-server free to use?

Yes — the hub reached it with no key and no payment.

What tools does inaturalist-mcp-server have?

10 tools: inaturalist_list_reference, inaturalist_get_taxon, inaturalist_get_leaderboard, inaturalist_find_places, inaturalist_resolve_name, inaturalist_get_observation, inaturalist_get_similar_species, inaturalist_get_histogram, ….

Is inaturalist-mcp-server safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• inaturalist_get_histogram reads open 19h ago

  Build a phenology histogram for a taxon in an area — which months, weeks, or years it is recorded in. The default month_of_year interval answers "when does this bloom or appear here" in twelve buckets; the absolute intervals (year, month, week, day, hour) bucket real dates and upstream applies a default start date to them. An area is given in exactly one form: place_id, the lat/lng/radius triple in kilometres, or a four-corner bounding box. Omit taxon_id to chart every taxon in the area. Narrow to one life stage or reproductive state with an annotation pair (term_id and term_value_id, e.g. Life Stage = Larva, or Flowers and Fruits = Flowers), or to broad groups with iconic_taxa. Defaults to research-grade, wild-only records and echoes those defaults back.

• inaturalist_search_observations reads open 19h ago

  Search georeferenced wildlife sightings by area, date, taxon, quality grade, annotation, conservation status, observer, project, and licence. Returns a projected record per sighting with coordinates, licence, first photo, and identification counts. An area is given in exactly one form — place_id, the lat/lng/radius triple in kilometres, or a four-corner bounding box — and defaults to research-grade, wild-only records, which are echoed back on every call. Identifications and comments are deliberately not expandable here (one thread is 28 KB); fetch them for specific records with inaturalist_get_observation. page walks the first 10,000 results under any ordering; past 10,000, order by id descending (order_by "id", order "desc") and pass each page’s next_cursor as cursor.

• inaturalist_get_species_counts reads open 10h ago

  Rank the distinct species recorded in an area and period, most-observed first — the "what lives here" answer, without paging through individual sightings. An area is given in exactly one form: place_id, the lat/lng/radius triple in kilometres, or a four-corner bounding box. Narrow to a clade by passing taxon_id, e.g. the birds of a park, or to one observer or one project by user_id, user_login, or project_id. Defaults to research-grade, wild-only records and echoes those defaults back. For the most active people rather than the most recorded species, use inaturalist_get_leaderboard.

• inaturalist_list_reference reads unknown 10h ago

  Decode the vocabularies the other iNaturalist tools take as input: annotation attributes and values, quality grades, license codes, taxonomic ranks, iconic taxa, and IUCN conservation-status codes. An unrecognized filter value is not rejected upstream — it silently returns nothing — so read the codes here before filtering. Note that the conservation codes are the normalised csi search filter; a taxon record’s own conservation_statuses[].status is authority-specific free text and reads differently. With topic controlled_terms and a taxon_id, the response also carries which annotations identifiers have actually recorded for that taxon, with counts.

• inaturalist_get_taxon reads unknown 36m ago

  Fetch a taxon profile: the taxonomic path, per-authority conservation listings, the encyclopedia summary, the photo gallery, immediate children, and observation counts. Resolve a name to a taxon id with inaturalist_resolve_name first. The upstream record is 95 KB for a common species, so it is projected before anything else happens; a taxon that still overflows comes back as an outline of its sections with their byte sizes, and naming those sections in a re-call returns only those. The valid section names are summary, taxonomy, children, conservation, photos, and encyclopedia.

• inaturalist_get_leaderboard reads unknown 10h ago

  Rank the most active observers or identifiers for an area, period, and taxon — who knows this place or this group. kind selects which: observers are ranked by how many observations they recorded, identifiers by how many identifications they made. An area is given in exactly one form: place_id, the lat/lng/radius triple in kilometres, or a four-corner bounding box. Both endpoints rank only the top 500 entries, so page multiplied by per_page must stay at or below 500 — narrow the area, period, or taxon to bring someone further down into reach. For the most-recorded species rather than the most active people, use inaturalist_get_species_counts.

• inaturalist_find_places reads unknown 19h ago

  Resolve a place name to a place id, or list the places containing a map area. Pass q to match a place-name PREFIX, or all four of nelat, nelng, swlat and swlng to list every place covering that box — exactly one of the two, never both. Each result carries the bounding box, place type, and containment chain an area search needs. Place geometry is stripped: a single nearby response carries 247 KB of boundary polygons upstream, none of which reaches the caller.

• inaturalist_resolve_name reads unknown 2h ago

  Resolve a common or scientific name to a taxon id, or a place, project, or observer name to its id. Returns ranked candidates carrying the identifiers every other tool takes. A miss is a result rather than a failure: found comes back false with guidance naming why. Taxon lookup matches a name PREFIX, not words inside a name, so "monarch butterfly" misses where "monarch" hits.

• inaturalist_get_observation reads unknown 2h ago

  Fetch up to 10 observations by id with their community identification thread — who identified what, whether each identification agrees, and the consensus taxon the community landed on. The whole batch costs one upstream request, so resolving ten ids here is far cheaper than ten separate lookups. Records come back in the requested order. A missing id is reported per id in unresolved rather than failing the batch; the call fails only when nothing resolved. Long threads and long observation-field lists are cut to fit one response budget shared across the batch — up to 40 identifications, 40 comments, and 40 filled fields for a single id, 4 of each per record for ten — and every record reports the size of each array beside what it kept.

• inaturalist_get_similar_species reads unknown 2h ago

  List the taxa this one is most often misidentified as, ranked by how many times identifiers made the correction — the field-identification check before committing to a look-alike. Scope it to an area in exactly one form (place_id, the lat/lng/radius triple in kilometres, or a four-corner bounding box) to see the confusion set a specific region actually produces, or leave the area off for the global set. The taxon must be a genus or finer (genus, species, or below) — upstream keeps no confusion set for a family, order, or anything coarser. Resolve the organism name to a taxon id with inaturalist_resolve_name first.
