This is third-party code. Review the repository files before installing.

What it does

The plugin adds a set of 1C skills and the unica MCP server to Codex or Claude Code. Through it the agent creates and validates metadata, managed forms, roles, data composition schemas, external data processors and reports, searches BSL code and launches the platform when an operation needs it. Both agents share the same plugin directory. The core and individual engines are downloaded from releases on first use and verified by SHA-256.

Who it is for. For 1C developers working in Codex or Claude Code on platform 8.3.27.

Good fit when

  • You want the agent to create metadata objects and forms in the dump, not just write code
  • You need role and DCS checks without opening Designer
  • You work in Codex and want a ready 1C toolkit

Not a fit when

  • You use platform 8.3.26 or older
  • Your agent is neither Codex nor Claude Code

Security check

  • Creates and modifies metadata, forms and roles in the project

README in short

The README lists requirements and supported platform versions, and install, update and removal commands for Codex and Claude Code. It details core and engine delivery with hash checks, cache locations and preparing an offline image. There is a section on migrating from old versions and tool contract changes. Contributors get local Rust build instructions.

FAQ

Why are skills missing after install?

In Codex the skill list is fixed at the start of a task, so open a new one. In Claude Code run /reload-plugins or start a new session.

How do I upgrade from old versions?

For 0.3.0 to 0.7.4 the README provides a migration script via v0.7.8; newer versions use the normal update.
