Brapi MCP Server

The 25 tools it gives your agent

Extracted from the project's README - what brapi-mcp-server lets an agent do.

brapi_connect

- Authenticate to a BrAPI v2 server, register the connection under an alias, and return the full orientation envelope in one call.

brapi_server_info

- Re-fetch the orientation envelope for a registered alias, optionally forcing a capability refresh.

brapi_describe_filters

- List valid filter names for a BrAPI endpoint - companion lookup for extraFilters on any find_ tool.

brapi_find_studies

- Find studies by crop, trial type, season, location, or program, with distributions and dataframe spillover.

brapi_get_study

- Fetch a study with program/trial/location resolved and companion counts (observations, units, variables).

brapi_find_germplasm

- Find germplasm by name, synonym, accession, PUI, crop, or free text, with distributions and dataframe spillover.

brapi_get_germplasm

- Fetch a germplasm with attributes, direct parents, and companion counts (studies, parents, descendants).

brapi_walk_pedigree

- BFS-walk ancestry or descendancy as a deduplicated DAG with cycle detection and depth limits.

brapi_find_variables

- Find observation variables by name, trait class, ontology term, or free text, ranked via OntologyResolver.

brapi_find_observations

- Pull observation records by study, germplasm, variable, season, or unit, with dataframe spillover.

brapi_find_images

- Filter image metadata by unit, observation, study, ontology term, or MIME type. Bytes via brapi_get_image.

brapi_get_image

- Fetch image bytes for up to 5 imageDbIds inline as type: image content blocks.

brapi_find_locations

- Find research stations by country, type, abbreviation, or bounding box.

brapi_find_variants

- Find variant records by variant set, reference, or genomic region.

brapi_find_genotype_calls

- Pull genotype calls via async-search polling, bounded by an upstream pull ceiling.

brapi_dataframe_describe

- List dataframes (or describe one) with column schema, row counts, and originating-source provenance.

brapi_dataframe_query

- Run read-only SQL across in-memory dataframes (DuckDB-backed).

brapi_dataframe_drop

- _Opt-in._ Drop a dataframe by name. Idempotent.

brapi_dataframe_export

- _Opt-in, stdio-only._ Export a dataframe to disk as CSV, Parquet, or JSON.

brapi_build_phenotype_matrix

- Build a germplasm × trait matrix from one or more studies, materialized as a canvas dataframe.

brapi_germplasm_performance

- Per-variable performance aggregates (n, mean, median, sd, min, max) for a single germplasm across its studies.

brapi_export_genotype_matrix

- Export genotype calls for a variant set as a germplasm × variant matrix, plus VCF-lite / PLINK serialization.

brapi_submit_observations

- _Opt-in._ Two-phase observation write - preview validates, apply confirms and writes.

brapi_raw_get

- Passthrough to any BrAPI GET /{path} endpoint not covered by a curated tool.

brapi_raw_search

- Passthrough to any POST /search/{noun} endpoint, with async polling handled transparently.
