• Claude Code: claude mcp add --transport http sos-inventory https://sos-inventory.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": {
    "sos-inventory": {
      "url": "https://sos-inventory.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 you sign in with your SOS Inventory account.

Sign in with your SOS Inventory company account and approve access. The connecting user must be able to read the company user list. Access follows that user's SOS permissions.
