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.

Issues & Support

Use both together for full 1C+CRM AI workflows.
