Add 8 catalog adapters: n8n, Hostinger, GoDaddy, Viber, WHOOP, Packlink PRO, Zalo OA, Flipkart Seller - #1343

Summary

Adds eight catalog adapters for services people searched the catalog for and did not find (store, welcome page and in-chat setup search since 2026-10-06). All are built from the vendors' public API docs or OpenAPI specs; open-source MCP servers were only used to judge which operations matter.

Changes

• n8n (intl/n8n, API key, instance URL variable): 43 tools for workflows, executions, credentials, tags, variables, projects, users, audit and source control. Tools that only exist on n8n 2.x say so.
• Hostinger (intl/hostinger, bearer token): 53 tools for VPS (machines, actions, backups, snapshots, Docker, firewalls), domains, DNS zones and snapshots, billing (read only) and web hosting. Nothing that buys, renews or cancels.
• GoDaddy (intl/godaddy, Personal Access Token): 15 tools for domains, availability, suggestions, DNS records, contacts and settings. sso-key is deprecated for the Domains API through 2026, so the adapter uses the PAT. renew_domain costs money and installs switched off.
• Viber Bot (intl/viber, X-Viber-Auth-Token): 15 tools for account info, user details, online status, every message type, broadcast and webhook. errorWhen maps Viber's HTTP 200 error statuses.
• WHOOP (intl/whoop, OAuth2 authorization code): 11 read-only tools for profile, body measurements, cycles, recovery, sleep and workouts (API v2).
• Packlink PRO (intl/packlink, API key): 11 tools for quotes, services, drop-off points, shipments by reference, labels, tracking, warehouses and draft shipments. Paths come from Packlink's own Apache-2.0 plugin core (packlink-dev/ecommerce_module_core), since Packlink publishes no API reference.
• Zalo Official Account (intl/zalo-oa, pasted access token): 17 tools for OA info, quota, followers, tags, conversations, consultation messages and articles. Zalo's token endpoint needs a secret_key header, app_id and a single-use refresh token, which the OAuth2 engine cannot do, so the setup explains the ~25 hour token.
• Flipkart Seller (in/flipkart-seller, OAuth2 client credentials): 19 tools for listings, price and inventory, shipments, labels, invoices, manifests, dispatch and returns. Cancel installs switched off.
• Logos for all eight, catalog regenerated, quoted counts updated to 572, llms.txt regenerated.

Type

• New feature

Testing

• Added/updated unit tests: a .live.spec.ts per adapter (static assertions always run; live part behind RUN_<SLUG>_LIVE=1).

Commands (in packages/backend unless noted), all on this branch:

• node scripts/validate-adapters.mjs --warn (root): 586 adapters, 0 failed, no warnings for the new files.
• node scripts/adapter-count.mjs --check (root): OK, 572 adapters (27 keyless, 8902 tools).
• npx tsc --noEmit -p tsconfig.json: clean.
• npx eslint on the eight new specs: clean.
• npx jest src/adapters: 565 suites passed, 1 skipped; 19033 tests passed.
• npx jest --testPathIgnorePatterns src/adapters/: 246 suites passed, 3 skipped; 5057 tests passed.

No live calls were made. Open points to check with real credentials: GoDaddy's unfiltered GET /v1/domains/{domain}/records, Flipkart's token request as POST (docs show GET), Packlink drafts without source, WHOOP's 8-character state note.
