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.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
