mcp-1c

Overview

MCP-1C is a comprehensive MCP server that bridges AI assistants with 1C:Enterprise databases. It exposes 9 tools that allow AI to view configuration metadata, search through code, execute queries, and receive BSL syntax help, all while working with live database connections. Written in Go for zero dependencies, the server supports both local models and cloud services like Claude and GPT, ensuring users' data remains secure. The implementation features sharded indexing for fast code searches and non-blocking startup.
