one-s-mcp desktop AI assistant
one-s-mcp
A closed-source Windows app with a set of local MCP servers: indexes a 1C configuration with extensions and answers the agent from real code, not memory
Medium risk
We rate an entry medium when the tool runs code, makes network calls or reads project files. Check what exactly it does before installing.
Why this level
- Indexes the full source of the configuration and extensions locally on the machine
- Form and processor generation creates new project files from a task description
Install
Manual install
Download the installer at onesmcp.ru/download/, install the app on Windows, load your configuration's XML export, and check the assistant you use (Claude Code, Codex, Cursor, VS Code, OpenCode) in the auto-setup list: the app wires up the MCP connection itself.
This is third-party code. Review the repository files before installing.
What it does
The app parses a 1C configuration's XML export and its extensions, builds a semantic index and dependency graph locally, and serves this to an AI assistant through several MCP servers on 127.0.0.1: code and metadata with semantic search and a call graph, change-impact analysis, platform and SSL reference, a 190-diagnostic code checker, configuration diffing with a client-ready report, form and processor generation, and live-data analytics under the user's own read-only rights. Extensions are shown merged with the base configuration: added attributes and overrides are visible right away. Parsing and indexing run on the user's machine; only requests to the user's chosen model leave it.
Who it is for. For 1C analysts, developers and architects on Windows who need an assistant that knows the real configuration with extensions, not just generic documentation.
Good fit when
- You need to ask what breaks if an object changes, accounting for extensions
- You need to diff configurations and get a client-ready change report
- You need an assistant across several bases at once, switched with one click
Not a fit when
- You are not on Windows: no other OS is supported
- You need open source: the product is proprietary, distributed only as an installer from the vendor site
Example request
What breaks if I change the СуммаДокумента attribute in the posting logic, accounting for all extensionsLimitations
Source code is closed: the GitHub repository is a product landing page with links, not an installation source; the installer is downloaded from onesmcp.ru. Works only on Windows 10 or 11. Status is open beta, requiring an account with a confirmed email. NVIDIA GPU acceleration is optional; the product also works without it, just slower.
How to disable. Uninstall the app via Windows Control Panel; it removes its own entries from MCP client settings.

README in short
The bilingual README describes the product as a desktop app and a set of MCP servers for 1C:Enterprise, lists capabilities from semantic search and a call graph to configuration diffing and form generation, a connection table (stdio, Windows only, no external infrastructure), the open free beta status, and explicitly calls the repository a product page: source is closed, distributed via a website installer.
FAQ
Can this be installed from source on GitHub?
No, the repository is a product landing page, the source is closed, and the product is installed via the installer from onesmcp.ru.
Does configuration source code go to the cloud?
Parsing, indexing, search and the graph are computed locally on the machine; only the built-in agent's requests to the model whose key the user provided leave it.
