Connecting to LinkDeal via OAuth
Connect your AI agent to LinkDeal using OAuth. No API key needed. Works with Claude, Cursor, ChatGPT and any MCP client.
Last updated: 17 August 2026
LinkDeal supports OAuth 2.0 for MCP connections. This is the recommended way to connect your AI agent because it requires no API key management and works with a single click.
Why use OAuth?
Easier setup: Click connect, sign in with your LinkDeal account, and you are done. No copying API keys or editing config files.
More secure: No long-lived API keys to manage or rotate. OAuth tokens are automatically refreshed.
Works everywhere: Claude, Cursor, ChatGPT and any MCP-compatible client can use OAuth.
How OAuth connection works
- Your AI client discovers LinkDeal's MCP server at
https://app.linkdeal.ai/api/mcp - When you click Connect, your browser opens to LinkDeal's authorisation page
- You sign in with your LinkDeal account (or are already signed in)
- You approve the connection
- Your AI client receives access tokens automatically
- You can start using all 18 MCP tools immediately
Connecting Claude
- In Claude.ai or Claude Desktop, go to Settings > Connectors
- Click Add connector
- Enter LinkDeal as the name
- Enter
https://app.linkdeal.ai/api/mcpas the URL - Select OAuth from the Auth dropdown
- Click Connect
- Sign in with your LinkDeal account when prompted
Connecting Cursor
- In Cursor, go to Settings > MCP
- Click Add MCP Server
- Enter LinkDeal as the name
- Enter
https://app.linkdeal.ai/api/mcpas the URL - Select OAuth as the auth method
- Click Connect
- Sign in with your LinkDeal account when prompted
Connecting ChatGPT
- In ChatGPT, go to Settings > Connectors or click the + button in a conversation
- Search for LinkDeal or enter
https://app.linkdeal.ai/api/mcp - Click Connect
- Sign in with your LinkDeal account when prompted
ChatGPT only supports OAuth for MCP servers (not API keys).
Managing connections
You can view and revoke MCP connections from your LinkDeal Settings page:
- Go to Settings in LinkDeal
- Scroll to Connected Apps
- Click Revoke next to any connection you want to remove
Revoking a connection immediately stops that client from accessing your account.
OAuth vs API key
| Feature | OAuth | API Key |
|---|---|---|
| Setup time | 30 seconds | 2-5 minutes |
| Config files | None | Required |
| Key rotation | Automatic | Manual |
| Best for | Claude, Cursor, ChatGPT | CLI tools, custom agents |
We recommend OAuth for most users. Use API keys only when your client does not support OAuth (such as some CLI tools or custom integrations).
Troubleshooting
Cannot see OAuth option: Make sure your AI client supports OAuth for MCP. Update to the latest version.
Authorisation fails: Check that you are signed in to LinkDeal in your browser. Clear cookies and try again if needed.
Connection drops: OAuth tokens refresh automatically, but if you see auth errors, try disconnecting and reconnecting.
