Step-by-step guide to connecting Claude Desktop to a Business Central MCP server through a locally hosted Python proxy (bc-mcp-proxy), which reduces authentication and configuration complexity. It covers the Entra ID app registration with redirect URIs and API permissions, registering the app in Business Central, running the proxy setup, and adding the generated config to claude_desktop_config.json.

Key points

  • Use a local Python proxy to simplify Claude-to-MCP authentication and configuration
  • Create an Azure AD app registration with specific redirect URIs and API permissions
  • Register the Azure AD app in Business Central via Microsoft Entra Applications
  • Install bc-mcp-proxy Python package and run setup to generate configuration files
  • Add the proxy configuration to Claude Desktop’s claude_desktop_config.json file under mcpServers

Quotes

  • “You can now ask Claude questions about your Business Central data, and after a few prompts for your permission, it will provide results.” (Shows the end result - Claude can query Business Central data with proper authentication)
  • “This approach also works for VS Code and Cursor.” (Indicates the proxy method is compatible with multiple AI agents and development environments)
