Description

Adds a BigML integration covering all 45 operations listed in the OSS
catalog: project management (create/get/delete/list), source management
(get/update/list), external data connectors (create/get), saved
configurations (get/list), and read/list access across 34 of BigML's
computed-resource types (models, datasets, predictions, clusters, anomaly
detectors, and more - see "Operations" below for the scope note).

BigML's docs site (bigml.com/api) is a JavaScript-rendered SPA with no
static/downloadable spec. Ground truth for routing came from BigML's
official Python SDK (bigmlcom/python, 293 stars), which encodes every
resource path, HTTP verb, and the auth mechanism directly in code - and
every route, field shape, and edge case from the SDK was then re-confirmed
against a real live account before being trusted, including two corrections
the SDK's own docstrings would not have caught (see "Live corrections"
below).

Fixes #806

Docs: https://bigml.com/api
Catalog: https://corsair.dev/oss/bigml

Auth and transport

username + api_key, both required, sent as query-string parameters on
every request - confirmed from the SDK's _add_credentials method and
verified live. No OAuth, no per-project credential. Base URL
https://bigml.io/andromeda.

Per-resource REST convention, confirmed live against a real account, not
assumed from the SDK alone:

  • List: GET {resource} -> {meta, objects}
  • Create: POST {resource}
  • Get: GET {resource}/{id}
  • Update: PUT {resource}/{id} (confirmed live: a no-op source rename
    returned 202 Accepted - this API's real convention is PUT, not the
    POST-everywhere convention some other providers in this repo use)
  • Delete: DELETE {resource}/{id} -> 204 No Content

Every resource is keyed by its own resource field, a compound
{type}/{hex24} string that is globally unique across the account -
confirmed live, so no composite cache key is needed anywhere in this
plugin (unlike several other plugins in this repo whose ids are only
unique within a parent scope).

Pagination is limit/offset, not cursor-based - confirmed real by effect:
an invalid limit value 400s rather than being silently ignored, and
different offset values return different rows.

Rate limiting: plan-tiered 429 with a JSON error body; no documented
custom header, so the client honours the standard retry-after if present
and otherwise falls back to its own backoff. 402 (plan/task-limit) is
treated the same as 403 - both are non-retryable write rejections, not a
scope problem.

Live corrections

Two things the SDK alone would have gotten wrong, both caught by testing
against a real account rather than trusting the SDK's docstrings:

  • LIST_COMPOSITES is a real, separate /composite resource path.
    The SDK's own _create_composite method posts to the plain /source
    endpoint with a sources: [...] array, which looked like strong evidence
    that composites were just a filtered view of /source - flagged for live
    confirmation rather than assumed. The live account proved that guess
    wrong: /composite is its own top-level listing, distinct from /source.
  • External connector connection fields have a confirmed vocabulary,
    and the connector type is a top-level field, not nested.
    BigML's own
    validation error on an invalid connection key names the exact accepted
    set (host, hosts, port, database, use_ssl, verify_certs,
    user, password, http_auth, sslmode, master, timeout,
    indice), and a source: 'postgresql' field sent at the top level
    (not inside connection) is what BigML actually expects.
  • sources.update was missing two things its own catalog description
    names
    : "parsing configuration" and "field properties". A first pass
    scoped the operation to name/description/tags only; re-reading the
    catalog text caught the gap, and both are now modelled -
    sourceParser ({separator, locale, missingTokens}) and fields (a map
    from BigML's own field id to {name, label, description, optype}), both
    shapes taken from a real source's live response, not guessed. Confirmed
    live that both 400 with "Cannot update closed source" once a source has
    finished processing (true for essentially every source a caller would
    already have an id for) - documented at the schema, not silently dropped.
  • Every list operation was missing orderBy/filtering. The catalog
    explicitly promises "filtering, ordering, and pagination" on most list
    descriptions; a first pass only implemented pagination. Confirmed live
    that order_by=size/order_by=-size genuinely sort (and an invalid
    field name 400s rather than being ignored), and that arbitrary
    field=value query params genuinely filter (confirmed by effect: a
    nonexistent-name filter returns total_count: 0). Both are now wired
    into every one of the 38 list operations through one shared listQuery
    helper (endpoints/shared.ts) rather than per-endpoint, so none of them
    can drift out of sync with each other.

A real credential-exposure finding, and how it's handled

Two things confirmed live against a real account that this plugin has to
actively defend against, not just note:

  • BigML echoes a connector's password/user back in plaintext on
    every subsequent GET and in the LIST envelope - this is BigML's own
    API behaviour, not a bug here. externalConnectors is therefore the one
    resource this plugin never mirrors locally (schema/index.ts), and
    connection is deny-listed by name in logging.ts so no audit event can
    carry it either - both independently, and both proven with a
    mutation-tested guard (endpoints.test.ts: the deny-list fault was
    planted, watched to fail the intended test, then reverted).
  • BigML's own meta.next/meta.previous pagination links embed the
    live account's username/api_key directly in plain text.
    Confirmed
    live on GET /source?limit=1. client.ts's redactPaginationCredentials
    strips both query params from every response before it reaches a caller,
    applied centrally so no individual endpoint can forget it - also
    mutation-tested.

Operations

45 operations. Scope is deliberately project/source management plus
read/list access across the platform's computed-resource types - no
create/train operations for datasets, models, or predictions. Those
resources are computed asynchronously in BigML (create can return 202
while a background job runs, tracked via a status.code lifecycle
confirmed live even on project and source), and this catalog's scope
does not attempt to model that lifecycle for a synchronous tool call.

Family Ops Notes
Projects 4 create, get, delete, list
Sources 3 get, update, list (no create - not in catalog scope)
External connectors 2 create, get
Configurations 2 get, list
34 generic computed-resource types 34 list only - anomalies, datasets, models, predictions, clusters, and 29 more, each its own family (anomalies.list, datasets.list, ...) since they are independent resource types on the account, not variants of one another

Persistence

Entities keyed on their bare resource field. projects, sources,
configurations get their own typed entity, captured from live responses
(GET /project, GET /source) - not transcribed from docs, since BigML's
docs are unreadable without a browser. The 34 generic list-only types share
one conservative entity (the common envelope confirmed live on every
resource type checked: resource, name, category, created, status,
tags, and more) rather than fabricated per-type fields for resources this
account had no live examples of - a live pass against a populated account
is the natural next step to split these into per-type schemas.

externalConnectors is the one resource never cached - see "credential
exposure" above.

Tests

84 unit tests across 4 suites, all passing, 71 assertions.

  • endpoints.test.ts (59 tests) - all 45 operations, each asserting the
    exact method and path it calls; a coverage sweep pinning that the
    exercised set is precisely the 45 registered; caching tests including
    that external connectors are never cached; two privacy tests for the
    connection-credential deny-list (one mutation-tested); request-body
    tests for every write operation, including the new sourceParser/
    fields update surface; and a live-effect-confirmed test that orderBy
    and filter reach the query string correctly.
  • client.test.ts (6 tests) - base URL, auth query params, that an empty
    username or api key throws before any request is issued, body-on-write
    behaviour, error wrapping, and the pagination-credential redaction
    (mutation-tested: the redaction function was neutered, the intended test
    confirmed to fail, then reverted).
  • error-handlers.test.ts (7 tests) - each handler classified by status
    first, message text used only as the fallback for a bare Error, and an
    explicit proof that a status-bearing error is never message-sniffed even
    when its message contains another status's trigger word.
  • schema.test.ts (12 tests) - every entity parses from resource alone,
    rejects a keyless record, preserves unknown keys through .loose(), and
    the entity registry is pinned to exactly the 37 stores this plugin uses
    (34 generic + projects/sources/configurations), with externalConnectors
    explicitly asserted absent.

Checklist

  • I have run pnpm build and all packages build successfully
  • I have run pnpm test and all tests pass
  • I have added or updated tests where applicable

Additional Notes

No webhooks, no triggers. The catalog lists 0 triggers, and BigML's
REST API has no webhook or event-subscription resource of any kind.

Footprint. packages/bigml/ plus a three-line registration in
packages/corsair/core/constants.ts and the generated pnpm-lock.yaml
entry. No deletions, nothing else touched - R1 scope exactly.

Deliberately out of scope, named explicitly: create/train operations
for the 34 read-only computed-resource types (async lifecycle, not a fit
for this catalog); per-type field schemas for those same 34 types beyond
the common envelope (no live examples existed in the account this was
built against - flagged for a follow-up live pass rather than guessed).

Merge Risk: 🔵 Low · up to 7db9f

List operations can accept filters, but reserved pagination parameters may be overridden by filter fields, causing some requests to return the wrong page or ordering. The risk is localized and the PR is otherwise mergeable with explicit owner follow-up to protect those parameters.

Greptile Summary

The PR adds a complete BigML API-key plugin with 45 project, source, connector, configuration, and computed-resource operations. It also adds account-scoped persistence, credential-aware response and audit redaction, error classification, provider registration, and comprehensive endpoint/schema/client tests.

  • Routes BigML authentication through mandatory username and api_key query parameters.
  • Adds filtering, ordering, and offset pagination across list operations.
  • Avoids persisting or logging external-connector credentials and redacts credentials from pagination links.
  • Registers typed endpoint schemas, metadata, entities, and provider constants.

Confidence Score: 4/5

The PR appears safe to merge after addressing the non-blocking requirement to document the newly introduced unknown types.

The endpoint, authentication, persistence, redaction, and error-handling paths are coherently wired and tested; the only accepted concern is missing type-boundary documentation.

Consider a shared list-persistence helper.

The loop writes each record one at a time and awaits each write. The same loop shape also exists in packages/bigml/endpoints/sources.ts (Lines 86-90) and packages/bigml/endpoints/configurations.ts. If limit is large, the sequential writes add latency per page.

Extract one helper into packages/bigml/endpoints/persist.ts, for example cacheEntities(store, entity, records, { label }), and let that helper decide the concurrency strategy in one place.

10-21: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Consider retrying transient server errors.

Only 429 is retried today. A BigML 500, 502, 503, or 504 falls through to DEFAULT with maxRetries: 0, so one transient upstream failure fails the whole operation. All 45 operations in this plugin are reads or idempotent writes (GET, PUT, DELETE, plus project/connector POST), so a bounded retry on 5xx is safe for the read and PUT/DELETE paths.

If you keep POST non-retryable, restrict the new handler to 5xx on non-POST calls.

🔒 Security & Privacy | 🟡 Minor | ⚡ Quick win

Strengthen the "never caches a connector" assertion.

makeCtx never creates an externalConnectors store, so expect('externalConnectors' in db).toBe(false) passes regardless of handler behavior. The assertion cannot fail if a future change starts caching connectors into an existing store.

Assert that no store received the connector payload, and that the connector handlers performed no writes.

In `@packages/bigml/endpoints.test.ts` around lines 484 - 495, Strengthen the test
around ExternalConnectors.create and ExternalConnectors.get so it verifies the
connector payload was not written to any database store and that the handlers
performed no writes. Do not rely on the absence of the externalConnectors store
in makeCtx; inspect the available stores and write activity so the assertion
would fail if caching were introduced.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Prevent filter from overriding pagination parameters.

Line 51 spreads input.filter after limit, offset, and order_by. A reserved filter key replaces the explicit page parameter. Spread filter fields first, then assign the reserved parameters.

Proposed fix
 	return compact({
+		...(input.filter ? compact(input.filter) : {}),
 		limit: input.limit,
 		offset: input.offset,
 		order_by: input.orderBy,
-		...(input.filter ? compact(input.filter) : {}),
 	});

Update the sources.update description to match what the handler sends.

The description names only "name, description, or tags". The handler in packages/bigml/endpoints/sources.ts (Lines 50-62) also sends source_parser and fields. This metadata is surfaced to callers and agents, so it should state the full write surface of a write risk-level operation.

✏️ Proposed description fix
 	'sources.update': {
 		riskLevel: 'write',
-		description: "Update a data source's name, description, or tags",
+		description:
+			"Update a data source's name, description, tags, parser settings, or field properties",
 	},
