1c-rest-mcp MCP Server

io.github.theYahia/1c-rest-mcp

AI agent access to 1C:Enterprise ERP data via OData 3.0—read and write catalogs, documents, and registers without configuration extensions.

What is the 1c-rest-mcp MCP server?

The aprovodka MCP server enables AI agents to read and write live 1C:Enterprise database data through the platform's native OData 3.0 interface, without requiring BSL code or database extensions. It covers catalogs, documents, all register types, constants, batch operations, and change tracking with built-in write-safety gates.

aprovodka bridges 1C:Enterprise ERP systems to AI agents, exposing business data (catalogs, documents, accounting registers, balances, turnovers) via OData. Unlike comparable servers, it requires no configuration extension, supports both reads and writes, and includes three write-safety modes (off, preview, approval) plus curated presets for БП 3.0, УТ 11, ЗУП 3.1, and ERP 2. Use it to automate data queries, create and update documents, post/unpost entries, and manage deletion marks directly from an AI agent.

Tools & capabilities

Tools this server exposes to the agent.

  • Catalog read/write — Query and update 1C catalogs via OData
  • Document operations — Create, update, post, unpost, and delete documents
  • Register access — Read and write all four register kinds including accounting registers with virtual tables (balances, turnovers, ext-dimensions)
  • Constants management — Read and update 1C constants
  • Batch operations — Execute batch operations on multiple records
  • Change tracking — Monitor and retrieve database change history
  • Metadata discovery — Inspect schema and available entities

Use cases

  • Query 1C catalogs and documents to retrieve current inventory, pricing, or customer data for reporting or analysis
  • Create and post accounting documents (invoices, purchase orders, journal entries) directly from an AI workflow without manual 1C entry
  • Update product catalogs, prices, or customer information in bulk via batch operations
  • Track changes and audit document modifications across the 1C database
  • Generate balance sheets and turnover reports by querying accounting registers and virtual tables

1c-rest-mcp MCP server FAQ

What is aprovodka?

aprovodka is an MCP server that connects AI agents to 1C:Enterprise ERP systems via the platform's native OData 3.0 interface. It allows reading and writing catalogs, documents, registers, and other business data without requiring database extensions or BSL code.

Is it free?

Yes, the server is free and open-source (MIT license). A paid service is available for schema validation and data accuracy verification against your specific 1C configuration (12,000 ₽ per database).

How do I install it?

Install via npm: `npm install @theyahia/aprovodka` or run `npx -y @theyahia/aprovodka`. Configure it in your MCP client with environment variables: ONEC_BASE_URL, ONEC_LOGIN, and ONEC_PASSWORD pointing to your 1C OData endpoint.

What authentication is required?

You need valid 1C:Enterprise OData credentials (username and password) and the OData 3.0 interface must be published on your 1C server. Credentials are passed via ONEC_LOGIN and ONEC_PASSWORD environment variables.

Can I write data, or only read?

You can both read and write. The server supports creating and updating documents, posting/unposting entries, and deletion marks. Write operations are protected by three safety modes: off (disabled), preview (show changes without applying), and approval (require explicit confirmation).

What 1C configurations are supported?

The server works with any 1C:Enterprise configuration that publishes OData. Curated presets are available for БП 3.0, УТ 11, ЗУП 3.1, and ERP 2, with pre-configured entities and known pitfalls documented.

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

{
  "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.
