Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| NES_LTER_CACHE_TTL | No | In-memory cache duration in seconds | 900 |
| NES_LTER_API_BASE_URL | No | Override the API base URL | https://nes-lter-api.whoi.edu |
| NES_LTER_MAX_CONCURRENCY | No | Maximum concurrent API requests | 8 |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| list_stationsB | List standard NES-LTER stations with coordinates and station metadata. |
| find_cruisesB | Find cruises by year, meteorological season, and type. |
| list_castsC | List casts, optionally restricted to the nearest standard station. |
| get_cast_profileC | Get one CTD profile, optionally compact and depth-filtered. |
| query_ctdC | Batch CTD query. Returns compact cast summaries unless include_points is true. |
| get_station_profileC | Compatibility wrapper for station profile lookup; use query_ctd for compact results. |
| list_dataset_rowsC | Fetch and filter underway, bottles, nutrients, HPLC, chlorophyll, or event rows. |
| get_cruise_trackC | Return the API's cruise track resource URL for client-side map use. |
| get_dataset_schemaC | Infer available columns and example values for a cruise dataset. |
| resolve_variableC | Resolve a friendly variable name to candidate API columns. |

TDQS
Scored across 10 tools
Most tools are distinct (stations, cruises, casts, CTD, track, schema, variable resolution). However, get_cast_profile vs query_ctd overlap since both return CTD profiles, and get_station_profile is explicitly a compatibility wrapper that duplicates query_ctd purpose—creating real misselection risk.
Most tools follow a consistent verb_noun pattern (list_, find_, get_, query_). Minor deviations exist with get_cruise_track (returns a URL rather than track data) and resolve_variable (verb_object but semantically different), but overall patterns are predictable.
Ten tools is a reasonable count for an oceanographic data server covering stations, cruises, CTD casts, datasets, schema, and variable resolution. Slightly heavy but each tool addresses a distinct lookup/query need within the domain.
The surface covers the full NES-LTER data lifecycle: station discovery, cruise search, cast listing, profile retrieval, batch queries, dataset row fetching, schema introspection, and variable resolution. The get_station_profile wrapper suggests legacy coverage, and no obvious dead ends exist for a data-retrieval server.
