aprovodka

MCP server for 1C:Enterprise — an AI agent reads and writes live 1C database data through the platform's own OData 3.0 interface. No configuration extension, no BSL.

npm License: MIT

34 tools · 11 modules · Node.js 18+ · stdio + Streamable HTTP

📄 Сайт продукта и услуги · 📖 Руководство пользователя (рус., 75 стр.) · 💬 Заказать сверку цифр

Terminal
npx -y @theyahia/aprovodka

Схема вашей базы + сверка цифр — 12 000 ₽

Сервер бесплатный и открытый. Платная — работа по вашей базе, где всё держится на одном: самоделка на OData не падает, она молча отдаёт неверное число. Проверить это можно только на конкретной конфигурации.

Что входит, за одну информационную базу:

  • файл схемы под вашу конфигурацию — какие сущности есть, как они называются, что с чем связано;
  • список ловушек именно вашей базы — где запрос вернёт правдоподобное, но неверное;
  • отчёт сверки по 10 согласованным вопросам — ответ агента стоит рядом с цифрой из вашего же штатного отчёта 1С, строка в строку.

Срок — 5 рабочих дней. Приёмка — по совпадению цифр, критерий согласуем до начала. Предоплата 100%, чек НПД. Условия целиком — договор-оферта.

What it does

Business data in a 1C database is closed to outside programs until someone writes a report, an external data processor, or an exchange for it. aprovodka removes that cycle: the OData 3.0 interface is published by the platform itself, and that is enough.

Coverage: catalogs, documents, all four register kinds, the accounting register including its virtual tables (balances, turnovers, ext-dimensions), constants, batch operations, change tracking, and metadata discovery.

What makes it different from the rest of the niche:

  • No BSL, nothing installed into the configuration. Six of the eight comparable servers require an extension in the database; the two that don't, don't touch live data.
  • Writes, not just reads. Create and update documents, post and unpost, deletion marks.
  • A write-safety gate. Three modes — off, preview, approval — intercepted at a single point in the client, so no tool can bypass it. Reversible operations return a rollback token; irreversible ones are labelled with the reason.
  • Curated configuration presets for БП 3.0, УТ 11, ЗУП 3.1 and ERP 2 — key entities with Russian descriptions, ready query examples, and the traps people hit.

Configuration

config.json
{
  "mcpServers": {
    "aprovodka": {
      "command": "npx",
      "args": ["-y", "@theyahia/aprovodka"],
      "env": {
        "ONEC_BASE_URL": "https://server/base/odata/standard.odata",
        "ONEC_LOGIN": "user",
        "ONEC_PASSWORD": "pass"
      }
    }
  }
}

Set ONEC_WRITE_MODE to preview or approval to enable the write gate (off by default, byte-for-byte the previous behaviour). Full environment reference, per-tool documentation and the module filter are in the monorepo README.

Where the code lives

Source, tests and releases live in the theYahia/WWmcp monorepo, alongside the shared @theyahia/mcp-core. This repository is the product's front page.

Migrating from @theyahia/1c-rest-mcp

The package was renamed in v4.0.0 — «1С» may not be used in a product's name (Infostart rules, § 2.2.11). The old package is frozen at v3.2.0.

  • Install: npx -y @theyahia/aprovodka
  • Binary renamed: 1c-rest-mcp → aprovodka
  • Server name in the MCP handshake is now aprovodka — update the key if you pinned it

Everything else is unchanged: tool names, arguments, return formats, prompts, and the ONEC_* environment variables (the 1C_* aliases still work). No config changes beyond the command.

Trademarks

aprovodka is an independent product. It is not a product of 1C Company and is not affiliated with it. «1С» and «1С:Предприятие» are trademarks of 1C Company; this product's name contains neither. Interaction with the database happens only through the open OData interface the platform itself provides.
