Minty MCP

Minty MCP is a remote Model Context Protocol server for shopping assistance. It helps AI clients find:

• coupon codes
• cashback opportunities
• store offers and promotions

Endpoint

https://mcp.minty.com/mcp

What You Get

• A remote MCP server that can be added to supported AI clients
• A focused v2 toolset for coupons, cashback, and promotional offers
• Structured responses that are easy for MCP-compatible clients to render or summarize

Supported Client Targets

• ChatGPT
• Claude

Compatibility can vary by client version and MCP feature support. Core tool calls should rely on the MCP endpoint and structured tool results, not on any client-specific UI behavior.

Quick Connect

Use the Minty MCP endpoint in your AI client:

https://mcp.minty.com/mcp

If your client asks for a server URL, use the endpoint above directly.

How To Use

Minty MCP can be added manually to supported AI clients by using the remote server URL below:

https://mcp.minty.com/mcp

After adding the server, start a new chat or session and try prompts such as:

• Find store offers for Target
• What cashback is available for beauty products?
• Find coupon codes for Sephora

Result Clicks And Sign-In

Minty MCP lookups are free and anonymous. The tools can return current coupons, cashback, and store offers without requiring a Minty sign-in inside ChatGPT or Claude.

The tools themselves are unauthenticated, so lookup requests do not include a Minty user session. Results are not personalized, and the tools do not expose shopper balance, order history, cashback history, or account-specific recommendations.

When a shopper clicks a cashback, offer, or coupon result, the click routes through the Minty web interstitial before continuing to the merchant. The interstitial asks the shopper to sign in with an email address so Minty can attribute the shopping session. After sign-in, Minty sends the shopper to the merchant.

Cashback can only be credited after the shopper signs in through Minty and completes the qualifying merchant purchase flow.

Client Plan Availability

In the current tested setup, Minty MCP can be connected manually from logged-in Free accounts in both ChatGPT and Claude. No paid ChatGPT or Claude plan is required for basic Minty lookup usage.

• ChatGPT: sign in, enable Developer mode in Plugins, then add Minty manually.
• Claude: sign in and add Minty as a custom connector. Claude Free may be limited to one custom connector.

Availability can vary by account rollout, workspace policy, region, and client surface.

1. Open ChatGPT and sign in.
2. Go to Settings.
3. Open Plugins.

You can open Plugins from the left sidebar or from Settings -> Plugins.

If you do not see Plugins, Developer mode, or the top-right + button, confirm that you are signed in and Developer mode is enabled. Availability may also vary by rollout, region, workspace policy, or client surface.

1. Open Claude.
2. Go to Settings.
3. Open Connectors.

Tool Set

This public documentation focuses on the 3 v2 tools:

1. find_store_offers
2. find_product_cashback
3. find_coupon_codes

Troubleshooting

• If ChatGPT or Claude does not show any Minty tools after setup, start a new chat or session and try again.
• If your client rejects the server URL, verify that you entered https://mcp.minty.com/mcp exactly.
• If ChatGPT does not expose custom MCP setup, confirm that Developer mode is enabled in Plugins.
• If Claude reports connection failures, remove the custom connector and add it again with the exact server URL.
• If a clicked result asks for an email sign-in on Minty, that is expected. Lookup is anonymous, but earning cashback requires sign-in.
• If results are not personalized or do not include balance or order history, that is expected because the public MCP tools are unauthenticated.
