brapi-mcp-server
Registry code: a39d29bc325774d8
Bridges BrAPI v2 servers (Breeding API for plant/crop research). Call `brapi_connect` first to register a server under an alias and return the orientation envelope (capabilities, dialect, content summary, the finders the server supports). `brapi_find_*` tools page filtered lookups across studies, germplasm, observations, variables, locations, images, variants, and genotype calls; rows beyond the per-call cap spill to a canvas dataframe — query with `brapi_dataframe_query` (SELECT-only SQL). `brapi_get_*` fetch single records by `*DbId`. Use `brapi_raw_get` / `brapi_raw_search` only when no…

- Is brapi-mcp-server live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 99% of checks over the last 30 days.
- Is brapi-mcp-server free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does brapi-mcp-server have?
- 22 tools: brapi_connect, brapi_export_genotype_matrix, brapi_dataframe_query, brapi_walk_pedigree, brapi_get_image, brapi_get_study, brapi_build_phenotype_matrix, brapi_raw_get, ….
- Is brapi-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.

brapi_find_studies reads open 20h ago
Locate studies matching crop, trial type, season, location, or program. Enriches results with program/trial/location context in one call. When the upstream total exceeds loadLimit, the full result set is materialized as a dataframe — query it with brapi_dataframe_query (SQL).

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 parameter restricts rows to a latitude/longitude window. When the spec-correct GeoJSON [lon, lat, alt] reading produces zero matches and at least one row carries a Point geometry, the bbox filter retries once with axes swapped (handles non-conformant servers that store [lat, lon, alt]) and surfaces a warning + `coordinateAxisOrder: "swapped"`.

Open a connection to a BrAPI v2 server, authenticate, and return the full orientation envelope (server identity, capability profile, content summary, suggested next tools). Required handshake before other BrAPI tools. Supports multiple concurrent connections via named aliases. Credentials can be configured server-side and omitted from this call. When a request carries no MCP session on a deployment without per-user auth, aliases live in one namespace shared by every such caller: re-registering an alias re-points their later calls to it. Built-in known servers (callable with no `baseUrl` or `auth` — public BrAPI v2 endpoints): `bti-breedbase-demo`, `bti-cassava`, `bti-sweetpotato`. Operator-configured aliases on this deployment (credentials and/or baseUrl read from server env vars): `default`, `cassava`. Aliases are shortcuts only; any other BrAPI v2 server is reachable by passing `baseUrl` directly.

Run SQL across in-memory dataframes. Dataframes auto-populate when find_* tools spill (named `df_<uuid>`) — 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_dataframe_describe to inspect schema and provenance for a known name. SELECT only — writes/DDL/COPY/PRAGMA/ATTACH/file-reads are rejected. Use SQL as the paging idiom: `LIMIT/OFFSET` to walk results, projection to trim columns, aggregation to summarize. Use `registerAs` to chain — the result lands as a new dataframe.

Aggregate a single germplasm's observations across every study it appears in, returning per-variable summary statistics (n, mean, median, sd, min, max), the contributing studies, and seasons. Study-anchored: discovers the germplasm's studies first (with a dialect-honor cross-check, capped at 200 studies), then pulls observations per study — avoids the unanchored germplasm-only pull that stalls on SGN/Breedbase. Pass an explicit studyDbIds set to skip discovery and its 200-study cap — e.g. process a chunk of the full study list retrieved via brapi_find_studies with extraFilters.germplasmDbIds.

Pull genotype calls for a germplasm × variant set. Filter to bound cost — at minimum, set `variantSetDbId` or `germplasmDbIds`.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's ida39d29bc325774d8.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/a39d29bc325774d8/claim.
Over MCP: the claim_endpoint tool.
[](https://brick.blue/agent/a39d29bc325774d8?ref=badge)
The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
