Connecting clients

The Deel MCP server is compatible with any client that implements the Model Context Protocol over HTTP transport. This page provides setup instructions for common AI clients.

The server URL for all clients is:

https://api.letsdeel.com/mcp

Client setup

Add the following to your ~/.cursor/mcp.json file. To learn more, see the Cursor documentation.

1{
2 "mcpServers": {
3 "deel": {
4 "url": "https://api.letsdeel.com/mcp"
5 }
6 }
7}

Cursor supports OAuth2 natively. When you first use a Deel tool, Cursor redirects you to the Deel authorization screen to grant access.

Verifying your connection

After configuring your client, verify the connection by asking the AI agent to list available tools or perform a simple operation.

Example prompts to test the connection:

  • “List my Deel contracts”
  • “What time-off policies are available?”
  • “Show my organization details”

If the connection is successful, the agent invokes the appropriate Deel MCP tool and returns results from the Deel platform.

Troubleshooting

Cause: The MCP client has not completed the OAuth2 authorization flow, or the token has expired.

Solutions:

  • Restart the MCP connection in your client to trigger the OAuth2 flow
  • If using a personal access token, verify the token is valid and correctly formatted in the Authorization header
  • Check that the token has not expired (access tokens are valid for 1 hour)

Cause: The client is not discovering tools from the server.

Solutions:

  • Verify the server URL is exactly https://api.letsdeel.com/mcp (no trailing slash)
  • Confirm the client supports HTTP transport for MCP (not just stdio)
  • Restart the client and reconnect to the MCP server
  • Check client logs for connection errors

Cause: Network connectivity issues or firewall restrictions.

Solutions:

  • Verify you can reach https://api.letsdeel.com from your network
  • Check that your firewall or proxy allows outbound HTTPS connections to api.letsdeel.com
  • If you are behind a corporate proxy, configure your client to use the proxy settings
