sbis-mcp

Read-only MCP server for Saby (СБИС) EDI — list/read documents and counterparties via the official JSON-RPC API, so agents can see legally significant paperwork without copy-paste.

⚠️ Unofficial. Not affiliated with Tensor LLC / Saby. Needs your own Saby account with API access.
v0.1 is read-only. Digital signatures (КЭП) and write paths are out of scope until v0.2.

⚠️ Неофициальный. Не аффилирован с ООО «Тензор» / Saby. Нужен свой аккаунт.
v0.1 — только чтение. КЭП и запись — не в этом релизе.

Proof — seven tools (v0.1)

Writes (ЗаписатьДокумент, ПодготовитьДействие, …) stay off until v0.2 (writable, default false).
