Documentation: docs.keyfire.ru/elemctl

A command-line tool, MCP server and Python library for managing applications on the 1C:Enterprise.Element cloud platform (1cmycloud.com) through Console API v2.

elemctl covers an application's lifecycle on the platform without the web console: create an application, build a .xasm/.xlib build archive from project sources, upload the build, apply it to the application and make sure the apply actually happened (the platform can silently roll back), and manage development-environment branches, dumps and the technology version. The same engine is available in three ways: the elemctl command for the terminal and CI, an MCP server for AI agents (Claude Code and other MCP clients), and the elemctl Python module for your own scripts.

elemctl is a CLI tool, MCP server and Python library for the 1C:Enterprise.Element (1cmycloud) Console API: manage applications, upload builds and deploy with honest apply verification. The CLI output is plain JSON.

Development notes and updates (in Russian): the 1C × AI: engineering workshop Telegram channel.

Features

• Applications: list (with a client-side name filter and --brief cards), details, create, start, stop, delete, technology version, debug-session data (apps debug). Commands addressing one application accept its id or its exact name.
• Projects and builds: upload .xasm/.xlib, list builds, delete.
• Build from sources: package a project directory (Проект.yaml + modules) into a build archive with a manifest and git metadata. The version comes from the flag, the last build's counter or the CI run number in the environment (CI_PIPELINE_IID / GITHUB_RUN_NUMBER / BUILD_NUMBER), and the output carries it as a field. Descriptors written with English key spellings (Name/Vendor/Version) are read as well as Russian ones.
• One-command deploy: build -> upload -> apply -> restart -> verification that the apply actually took effect. Uncommitted changes of the project directory are reported (dirty in the report); --require-clean aborts on a dirty tree.
• Compilation check without risking the application (elemctl probe): the sources are compiled by the SERVER through a throwaway application, the errors come back with file, line and column, and the probe removes what it created. The working application is out of reach on purpose – ELEMENT_APP_ID and ELEMENT_PROJECT_ID are not used.
• User lists: the sign-in settings a control panel usually holds – self-registration and signing in with a login and a password (elemctl user-lists). The list is addressed by id, by presentation or by the application whose own list it is.
• Development-environment branches: list, create, bind to an application, merge.
• Dumps: create and check readiness.
• MCP server: the same operations exposed as tools for AI agents (Claude Code and other MCP clients).
• Plugins: importlib.metadata entry points – an external package supplies the platform debug adapter (elemctl debug-adapter) and commands of its own without bloating the core. One Command declaration becomes both a CLI subcommand and an MCP tool, so a command that knows about your own environment lives in your package rather than in a public core.
• Self-update: elemctl self-update – update the package by unpacking the wheel, even while elemctl.exe is held by a running MCP server (where plain pipx/pip would break the install).
• In VS Code: deploy and debugging live in the XBSL extension – it calls elemctl: elemctl deploy behind the deploy button, elemctl apps debug for the debug-session coordinates.

Honest apply verification

A platform quirk: if a project apply fails, the platform silently rolls back the application to the previous build – the Running status says nothing about whether the deploy succeeded. elemctl deploy therefore does not trust the status and, after the deploy, checks:

1. application tasks with the Error/Failed status that started after the deploy began (old errors from the history are ignored);
2. the application's actual project version (source.project-version) – it must match the build that was just uploaded;
3. the application uri's availability via a health-check HTTP request (informational, the uri-status field in the report: 401/403 are normal for closed applications).

The deploy exit code is zero only if the build was actually applied.

Installation

pipx install elemctl            # or: pip install elemctl
pip install "elemctl[mcp]"      # with the MCP server

Python 3.10+ is required. The core and CLI have no external dependencies (standard library only).

Configuration

Connection credentials are taken from environment variables or from a .env file in the current directory (environment variables take priority):

Client-Id/Client-Secret are issued in the 1cmycloud control panel (the Console API integrations section). A file template is .env.example.

Quick start

# list applications
elemctl apps list

# application details (status, uri, actual project version)
elemctl apps get <app-id>

# create the application only if it does not exist yet:
# {"id": ..., "created": true|false, "sign-in": ...} - the last field is the way in
elemctl apps ensure acme-crm-dev --project-id <project-id> --latest-build --wait

# full deploy cycle from sources with apply verification
elemctl deploy --app-id <app-id> --project-id <project-id> --project-dir acme/crm

# compile the sources on the server without touching the working application:
# ok, plus errors with file, line and column; cleans up after itself
elemctl probe --project-dir acme/crm

# debug-session data: {"debug-token": ..., "debug-address": ...}
# (debugging must be enabled on the server: config/debug.yml enabled: true)
elemctl apps debug <app-id>

# only build the .xasm archive, without uploading it anywhere
elemctl build --project-dir acme/crm --output ./dist

# parse a built archive: manifest, subsystems, global types with qualified names
elemctl inspect ./dist/e1c-CurrencyConverter-2.0.xlib

# forbid signing in by password and self-registration in the application's user list
elemctl user-lists password-login --app crm-dev --disable
elemctl user-lists self-registration --app crm-dev --disable

# merge changes from a development-environment branch
elemctl branches merge <branch-id>

All commands output JSON to stdout; progress of long-running operations goes to stderr. Errors are returned as a JSON object with an error field and exit code 1.

For the full list of commands: elemctl --help, and by group: elemctl apps --help, elemctl deploy --help, etc.

Language

Error and progress messages, and the --help text, come in Russian and English (the JSON result is language-neutral). The language is picked by --lang ru|en > the ELEMCTL_LANG env var > the system locale > Russian; --lang is read before the parser is built, so elemctl --lang en --help prints English help.

MCP server

The server exposes platform operations as MCP tools (stdio transport):

pip install "elemctl[mcp]"
claude mcp add elemctl -- elemctl mcp

The server reads connection credentials from the same ELEMENT_* variables / .env. Among the tools: list_apps, get_app, deploy (with an ok field in the response), probe (a compilation check that does not touch the working application), verify_deploy, list_builds, configure_user_list, merge_branch and others.

A single environment is not a limit: every tool that talks to the platform takes an optional env_file - a path to another installation's .env. One server thus serves both the cloud and a local installation without a restart with different credentials. list_apps returns brief cards by default (id, name, status, uri, applied version): full cards of a whole space are tens of thousands of characters in an agent's response - pass brief=false for them.

Plugins

elemctl discovers external packages through importlib.metadata entry points: it declares nothing about plugins in its own pyproject.toml and reads them on demand. This keeps non-publishable vendor artifacts in a separate package while the elemctl core stays clean and public.

One group is currently supported – elemctl.debug_adapter: a plugin package declares the directory of the platform debug adapter (proprietary 1C jars, not shipped with elemctl). The entry-point value is a path or a zero-argument callable returning a path; the path points to a directory that contains a repo/ subdirectory with the adapter jars.

# a plugin package's pyproject.toml
[project.entry-points."elemctl.debug_adapter"]
name = "my_package:adapter_root"     # () -> Path to the directory containing repo/

# the adapter path from the installed plugin (for the VS Code extension):
# {"path": "...", "found": true} or {"path": null, "found": false}
elemctl debug-adapter

# which plugins are visible – install diagnostics
elemctl plugins

The adapter itself (proprietary 1C jars) is extracted from the platform distribution by tools/extract_adapter.py – into a directory for a manual xbsl.debug.adapterPath, or for building the plugin package. The script is not shipped in the package distribution.

Plugin discovery is disabled by ELEMCTL_NO_PLUGINS=1 (a run with the core capabilities only).

VS Code

Two companion extensions integrate elemctl into the editor:

• XBSL (the xbsl project) – highlighting, linting, the form designer, the metadata tree, the XBSL: deploy the project button that runs elemctl deploy as a terminal task with the apply verification, and debugging 1C:Element applications through the platform's DAP adapter, whose session data comes from elemctl apps debug. Debugging used to be a separate XBSL Debug extension living in this repository; since XBSL 0.57 it is part of the one extension, and this repository keeps only the elemctl side of it.

It is also published to Open VSX.

Use as a library

from elemctl import Config, ElementClient
from elemctl.deploy import deploy_from_sources

client = ElementClient(Config.from_env())
apps = client.list_apps()

report = deploy_from_sources(
    client,
    app_id="...",
    project_id="...",
    project_dir="acme/crm",
    log=print,
)
assert report.ok, report.problems

Build format

.xasm (application) and .xlib (library) are a ZIP archive:

Assembly.yaml            # manifest: ProjectKind, Vendor, Name, Version, ...
{vendor}/{name}/...      # project files: .yaml, .xbsl, resources

The project directory must follow the {repo}/{vendor}/{name}/Проект.yaml layout – paths inside the archive are built relative to the repository root. The project kind (application/library) is determined by the ВидПроекта field in Проект.yaml. When an application references libraries whose source projects are present under the same repository root, their files are included in the application archive automatically (including transitive local dependencies). A referenced library that is not present locally remains an external platform dependency.

Limitations and status

• The tool is unofficial and not affiliated with 1C Company; the Console API may change without notice.
• Only the documented Console API v2 is used – the tool does not call or describe the platform console's internal APIs.
• Creating an application from --project-id alone produces, on some platform configurations, an empty skeleton without project data. The reliable path is a build source: elemctl apps create <name> --project-id <id> --latest-build (the create_app MCP tool substitutes the latest build automatically), followed by elemctl deploy after creation.
• An application created with an Error status is described by the platform only as "Неизвестная ошибка. Обратитесь к администратору"; the details - files, lines and columns of the compilation errors - live in the application's task. apps create --wait and apps ensure print them after the generic text, the way deploy and verify have long done, so there is no need to dig through the server log.
• There is no way to compile the sources without creating something on the platform: compilation is the server's and it happens when a build is applied. That is what probe is for – it takes the hit on a throwaway application instead of the working one. A probe run costs as long as creating an application does (minutes), so it belongs before a deploy or in CI, not in a per-keystroke loop.
• A platform project is identified by the Vendor + Name pair of the manifest, not by the Ид of Проект.yaml: a build upload without a project id lands in the project that already owns the pair, and a second project for the same pair is refused with a 409.
• A freshly created application is signed in to with a CONTROL PANEL account: it gets its OWN, empty user list, password sign-in is off and no account service is attached, so the accounts used to sign in to other applications do not work here – and neither connecting another application's user list nor enabling the local sign-in changes it. apps create and apps ensure say so themselves: the sign-in field of the answer plus the same on stderr.
• Deleted applications remain in the platform's list with a Deleted status and their former id, on which apps get and deploy return 404. apps find and apps ensure skip them; to restore the previous search behavior, use apps find --include-deleted.
• The platform will not let you delete an application that has unpublished changes in the development environment (HTTP 400 FAILED_PRECONDITION), and there is no forced deletion in the Console API – only through the control panel; elemctl points this out in the error message.
• Recreating an application (delete + create) changes its URL – external settings tied to the address (OIDC redirect, etc.) will need to be updated. There is no "soft" wipe of application data in the Console API; it is done in the management console.

Origin and legal notes
