MCP server for 1C Enterprise — ERP catalogs, documents via REST API (Russia)
Overview
Local MCP server that lets an AI assistant read and write live 1C:Enterprise business data through the platform's OData interface.
- What you can do
- Discover metadata and browse catalogs, documents, registers and constants in a 1C database via OData 3.0, including accounting virtual tables such as balances and turnovers, plus batch operations and change tracking (34 tools across 11 modules). Create and update documents, post and unpost them, and set deletion marks. Apply a write-safety gate in off, preview or approval mode, with rollback tokens for reversible operations and labels on irreversible ones. Use curated configuration presets for common Russian 1C configurations with ready query examples.
- When to use it
- Useful when an assistant needs to query or modify data in a live 1C:Enterprise database without writing reports, BSL code or a configuration extension, for example for ERP catalogs and documents.
- Requirements
- Runs locally over stdio with Node.js 18+ (npx package). Needs a published OData 3.0 endpoint and credentials supplied through ONEC_BASE_URL, ONEC_LOGIN and ONEC_PASSWORD; ONEC_WRITE_MODE controls the write gate.
Installation
In SourceWeft
- Open 1c-rest-mcp in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.

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.
34 tools · 11 modules · Node.js 18+ · stdio + Streamable HTTP
📄 Сайт продукта и услуги · 📖 Руководство пользователя (рус., 75 стр.) · 💬 Заказать сверку цифр
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.
📧 [email protected] · 💬 @metarebalancer — ответим в рабочие дни, 10:00–19:00 МСК. Напишите, какая у вас конфигурация и опубликован ли OData.
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
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.
