Data Separation

Data Separation

MCP routing

• Preferred path: use MCP unica tools unica.view {}, unica.search, unica.view on the object node, unica.view on the role node, unica.check, unica.docs, and unica.run.
• Runtime идёт через unica.run: вызов без op отдаёт словарь операций и контракт каждой — argsSchema, execution, previewRequired, ifRevRequiredOnApply. Контракт вызова бери оттуда, а не из этого текста; выбирай только операцию с implemented: true и не выдумывай аргументов записи с argsSchema: null; превью исполнением не является. Не обходи контракт прямым runner-ом.
• Use unica.view on the schema node when reports/DCS queries may bypass tenant filters.
• Do not call internal metadata, analyzer, standards, runtime, or package adapters directly. They are hidden behind MCP unica.

References

• Read ../../references/platform/platform-mechanics.md for tenant-boundaries, rights, temporary storage, background jobs, and exchange behavior.
• Read ../../references/platform/db-performance.md when separated data changes query plans, indexes, locks, or virtual table filters.
• Read ../../references/platform/runtime-diagnostics.md when the issue appears only in ЖР/ТЖ or runtime traces.

Workflow

1. Identify separation model: separator values, tenant ownership, user/session context, rights/RLS, privileged code, and external ids.
2. Inspect metadata and roles with unica.view on the object node and unica.view on the role node; find risky code with unica.search.
3. Trace tenant value through reads, writes, reports, background jobs, exchange messages, file batches, temp storage, and integration calls.
4. Review queries for missing tenant filters, unsafe privileged mode, broad virtual tables, and joins that cross boundaries.
5. Check syntax with unica.check (test runs are outside the v0.13 surface); record runtime verification as unavailable and require separate evidence covering at least two tenant contexts.

Red flags

• Code writes objects without setting separator attributes.
• Background job runs under a broad user context and processes all tenants.
• Exchange or integration payload omits tenant/external owner id.
• Report/DCS query uses privileged access without a documented reason.
• Temporary storage or files are shared across tenant/session boundaries.

Contract gaps

If public MCP unica cannot expose separation metadata, role details, or runtime context required for the task, report a Unica MCP contract gap.
