What is Infaton MCP35?

Infaton MCP35 is a Model Context Protocol (MCP) server for 1C:Enterprise that provides 51 tools for AI assistants to interact with a 1C database. It uses JSON-RPC 2.0 over HTTP (Basic Auth) or stdio (via a Node.js wrapper). It is built as a 1C configuration extension (INFATON_MCP.cfe) and is intended for developers and administrators who want to integrate AI agents with 1C:Enterprise systems (ERP, Accounting, Trade Management, etc.).

How to use Infaton MCP35?

Install the INFATON_MCP.cfe extension in your 1C database (via Configurator). Then configure an MCP client (e.g., Claude Desktop, Cursor) with the command npx infaton-mcp (or node index.mjs) and environment variables ONEC_URL, ONEC_USER, ONEC_PASSWORD. Alternatively, make direct HTTP POST requests to the /hs/mcp/ endpoint with JSON-RPC 2.0 payloads.

FAQ from Infaton MCP35

What 1C platforms and configurations are supported?

1C platform 8.3.20+ (tested on 8.3.27.1989). Compatible with ERP 2.5, UPP 1.3, Accounting 3.0, UT 11, and KA 2.

What transports and authentication are supported?

HTTP with Basic Auth (username/password) and stdio (via a Node.js wrapper, index.mjs). For production, HTTPS is required to protect credentials.

What are the dangerous tools and how to restrict them?

execute_code, delete_object, run_scheduled_job, import_data, post_document, and unpost_document are considered risky. Use the ONEC_ALLOWED_TOOLS environment variable to whitelist only safe tools for read-only scenarios.

How is the MCP server installed on the 1C side?

Install the INFATON_MCP.cfe extension in the Configurator (Configuration → Extensions → Add), then update the database with F7. The HTTP service is automatically published at /hs/mcp/.

Does Infaton MCP35 require Node.js?

Node.js 18+ is only required for the stdio transport wrapper (index.mjs). Direct HTTP calls to the 1C service do not require Node.js.
