VerifiedSTDIODesktop onlyDatabasesBusiness & Commerce

Overview

AI-generated overview

Local MCP server that connects an AI assistant to a 1C:Enterprise database to read CRM/ERP records and, on paid tiers, create documents and postings.

What you can do
Read invoices, contracts and partners from a 1C:Enterprise database through conversation with the assistant (Solo tier, read-only). Create documents and conduct postings in 1C when a Pro or Team license is active. Work alongside a Bitrix24 MCP server for combined 1C and CRM workflows. The manifest lists no individual tools; capabilities come from the description and README.
When to use it
Useful when you work with 1C:Enterprise CRM/ERP data and want an assistant to look up invoices, contracts or partners, or to draft and post documents without switching to the 1C interface.
Requirements
Runs locally over stdio as an npm package; version 0.1.6 needs Python 3.10–3.13 on Linux, macOS or Windows x86_64. Requires the MCPService extension installed in the 1C database, plus MCP_1C_BASE (service URL), MCP_1C_USER, MCP_1C_PASSWORD and a RCS_LICENSE_KEY. A free Solo license is obtained by email request; the server checks the license online.
Before you install
The server can write to the 1C database (create documents, conduct postings) on paid tiers, so changes affect real business records. It needs a 1C user password (MCP_1C_PASSWORD) and a license key (RCS_LICENSE_KEY). Paid tiers cost 9,900 or 39,900 KZT per month. The Python server ships as obfuscated bytecode and verifies its license online, so review the package's security notes before use.

Installation

In SourceWeft

  1. Open Mcp 1c in the dashboard and add it to a workspace.
  2. 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.

Source code

This repository contains documentation, install guides, and the MCPService 1C extension (.cfe source).

The Python MCP server source is NOT in this repository. The runtime ships only via npm (@rcs-kz/mcp-1c) as PyArmor-obfuscated bytecode. This protects the maintainer's IP while allowing transparent license verification (server runs locally, only checks license online).

For security audit, threat model, and trust questions — see NOTICE.md in the npm package.
