Values you fill in

• BRAPI_DEFAULT_BASE_URL env
  Default BrAPI v2 base URL. Optional — connections can be opened at runtime via the brapi_connect tool instead.
• BRAPI_ENABLE_WRITES env
  Opt-in flag for the write surface (brapi_submit_observations). Off by default — the tool is omitted from tools/list unless the operator opts in.
• BRAPI_PAGE_SIZE env
  Upstream pageSize used during canvas spillover walks (decoupled from BRAPI_LOAD_LIMIT). Dataframe ceiling = pageSize × 50 pages, capped at 50,000 rows.
• MCP_LOG_LEVEL env
  Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

• brapi_connect

  Open a connection to a BrAPI v2 server, authenticate, and return the full orientation envelope (server identity, capability profile, content summary, suggested next tools). Other BrAPI tools connect an alias the server has a URL configured for (a built-in or operator-configured a

• brapi_build_phenotype_matrix

  Pull observations across one or more studies and pivot them into a germplasm × trait matrix materialized as a canvas dataframe. Returns a dataframe handle (read it with brapi_dataframe_describe and brapi_dataframe_query) plus a summary of dimensions and aggregate method. Long-for

• brapi_server_info

  Return the full orientation envelope for a BrAPI connection — server identity, capabilities, content counts, suggested finders, and notes. Pass forceRefresh to refetch the cached capability scan; pass an alias to read a non-default connection.

• brapi_describe_filters

  List the valid filter names for a BrAPI endpoint (studies, germplasm, observations, variables, images, variants, locations) — companion lookup for the `extraFilters` passthrough on any `find_*` tool. Entries reflect the BrAPI v2.1 spec; individual servers may implement subsets.

• brapi_find_studies

  Locate studies matching crop, trial type, season, location, or program. Enriches results with program/trial/location context in one call. results[] holds the leading matches up to loadLimit and a 24,000-byte budget; when it holds fewer rows than matched, the matched set is materi

• brapi_get_study

  Fetch a single study by DbId with its program, trial, and location records resolved where those lookups succeed. Response includes cheap observation/observation-unit/variable counts as drill-down signals.

• brapi_find_germplasm

  Find germplasm by name, synonym, accession number, PUI, crop, or free-text query. Matches across registered synonyms. results[] holds the leading matches up to loadLimit and a 24,000-byte budget; when it holds fewer rows than matched, the matched set is materialized as a datafram

• brapi_get_germplasm

  Fetch a single germplasm by DbId with attributes and direct parents. Response companions report study count, direct parent count, and direct descendant count — signals for pedigree depth and observation coverage.

• brapi_walk_pedigree

  Walk germplasm ancestry or descendancy as a deduplicated DAG with cycle detection and depth limits. leafCount counts graph terminals, confirmedLeafCount counts successfully verified leaves, and frontier records unresolved directions. Nodes and edges each fit loadLimit and a 24,00

• brapi_germplasm_performance

  Aggregate a single germplasm's observations across studies, returning per-variable statistics (n, mean, median, sd, min, max), contributing studies, seasons, and collection coverage. SGN/Breedbase uses advertised germplasm-scoped observation units with embedded measurements, incl

• brapi_find_variables

  Find observation variables (traits) by name, trait class, ontology term, or free-text query. Free-text queries are ranked against every fetched row by PUI, name, synonym, and trait text; a candidate carries the ontology PUI of its row as termId when the row has one. results[] hol

• brapi_find_observations

  Pull observation records filtered by study, germplasm, variable, season, or observation unit. Without a studies, trials, observationUnits, or observations anchor, a GET query first runs a one-row count probe and skips the bulk pull (warnings says so) when the probe fails or repor

• brapi_find_images

  Filter images by observation unit, observation, study, descriptive ontology term, file name, or MIME type. Returns metadata only — use brapi_get_image to fetch bytes inline. results[] holds the leading matches up to loadLimit and a 24,000-byte budget; when it holds fewer rows tha

• brapi_get_image

  Fetch image bytes for up to 5 imageDbIds and return them inline as `type: image` content blocks. Falls back to the metadata `imageURL` when the server lacks dedicated image-content delivery or that request fails. No filesystem side-effects.

• brapi_find_locations

  Find research stations / field sites by country, abbreviation, type, location ID, or free-text. Countries filter by ISO 3166-1 alpha-3 code via countryCodes, or by free-form English country name via countryNames (resolved client-side to alpha-3 — "Uganda" → "UGA"). Optional bbox

• brapi_find_variants

  Find variant records by variant set, reference sequence, or genomic region (start/end, 0-based inclusive / exclusive per the BrAPI spec; servers may differ). results[] holds the leading matches up to loadLimit and a 24,000-byte budget; when it holds fewer rows than matched, the m

• brapi_find_genotype_calls

  Pull genotype calls for a germplasm × variant set. Filter to bound cost — at minimum, set `variantSetDbId` or `germplasmDbIds`. The upstream pull is capped by deployment policy; when the pull is truncated, narrow the filters. results[] holds the leading calls up to `loadLimit` an

• brapi_export_genotype_matrix

  Pull genotype calls for a germplasm × variant set and pivot them into a matrix. `matrix-json` registers a wide canvas dataframe; `vcf-lite` adds VCF-subset text in `vcf`; `plink` adds .ped/.map text in `ped`/`map`. Text formats pull /variants metadata and convert zero-based BrAPI

• brapi_dataframe_describe

  Start here after a spillover. Lists dataframes (or describes one) with columns, row counts, and originating-source provenance. The dataframe name appears inline on every find_* response that spilled (`result.dataframe.tableName`) — pass it as `dataframe` to inspect schema and pro

• brapi_dataframe_query

  Run SQL across in-memory dataframes. Dataframes auto-populate when find_* tools spill (named `df_ `) — the dataframe name appears inline on every find_* response that spilled (`result.dataframe.tableName`), so the typical flow is find_* → read the name → query here. Use brapi_dat

• brapi_raw_get

  Passthrough to BrAPI GET /{path} without foreign-key resolution. List results (result array or result.data) return a leading preview within loadLimit and a 24,000-byte budget on each serialized row representation; an oversized first row returns no inline rows. Omitted fetched row

• brapi_raw_search

  Passthrough to BrAPI POST /search/{noun}, polling async search IDs. Sends loadLimit as the initial pageSize unless body.page/pageSize drives explicit paging. List previews fit loadLimit and a 24,000-byte budget on each serialized row representation; an oversized first row returns
