Lexware Office MCP by usefulapi

Lexware Office MCP by usefulapi

Use Lexware Office from Claude, Cursor, or any MCP client — read Lexware Office contacts, articles, invoices and vouchers; create contacts and draft invoices. Hosted, no local install: connect with your own Lexware Office credentials.

Live endpoint: https://lexware-office.usefulapi.io/mcp · Homepage: https://usefulapi.io/lexware-office

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://lexware-office.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http lexware-office https://lexware-office.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "lexware-office": {
      "url": "https://lexware-office.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Lexware Office credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/lexware-office/

On first connect you'll provide your Lexware Office Public API key. Your credentials are validated, stored per-user, and scoped to you — no keys in config files.
