What it does

The server connects an agent to Saby electronic document exchange through the official JSON-RPC API. The agent gets current user info, document lists and documents by event, reads a single document, lists counterparties and downloads attachments via a temporary link. There are seven tools in total, including a config view. Version 0.1 is read-only: writing documents and qualified signature actions are off and planned for the next version. You can point it at the Saby test environment instead of production.

Who it is for. For accountants, lawyers and developers who want an agent to go through incoming Saby documents.

Example request

Show incoming Saby documents from the last week and summarize the invoices from the counterparty Romashka LLC

Limitations

The project is unofficial and not affiliated with Tensor. You need your own Saby account with API access and the counterparty exchange plan. The server logs in with a login and password kept in environment variables or ~/.sbis-mcp/config.json. Saby limits apply: at most 300 auth calls per minute per IP and attachments up to 73 MB. Live-account testing is done manually by the author.

How to disable. Remove the sbis-mcp block from the MCP client config and delete ~/.sbis-mcp/config.json if you created it. Consider changing your Saby password afterwards.

README in short

The bilingual README warns that the server is unofficial and read-only in its first version. It maps each tool to the Saby API method behind it. It covers configuration via environment variables or a config file, building from source and a Claude Desktop example using npx. Saby limits are listed with links to the docs, along with a manual smoke test against a live account. MIT licensed.
