Claude Code

claude mcp add softeria-ms-365-mcp-server -- npx -y @softeria/ms-365-mcp-server

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "softeria-ms-365-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "@softeria/ms-365-mcp-server"
      ]
    }
  }
