Browse affiliates, referrals, commissions and payouts, and set up campaigns and affiliates. Hosted by usefulapi — connect from Claude, ChatGPT, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"rewardful": {
"url": "https://rewardful.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"rewardful": {
"type": "http",
"url": "https://rewardful.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
The login page asks for your Rewardful API Secret.
Find it in Rewardful → Company settings (app.getrewardful.com/company/edit), in the API section: copy the API Secret, not the public API Key used by the tracking snippet. Your secret is used only to call the Rewardful API on your behalf and to derive a private account id; it is never shown to anyone.
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: the login page asks for your Rewardful API Secret. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
Turn on the Rewardful connector, then ask in plain words. The AI picks the tools.

rewardful_create_affiliate | write | Create an affiliate Add an affiliate (or a customer referrer, by passing stripe_customer_id). Rewardful sends NO welcome email for API-created affiliates. Rewardful: POST /v1/affiliates. |
rewardful_update_affiliate | write | Update an affiliate Change an affiliate's name, email, payout emails, notifications, campaign (moves them) or state. Setting state to disabled stops tracking and earning; set it back to active to undo. Rewardful: PUT /v1/affiliates/:id. |
rewardful_create_affiliate_link | write | Create an affiliate link Give an affiliate an additional tracking link. A token is generated if omitted. Growth/Enterprise plans only. Rewardful: POST /v1/affiliate_links. |
rewardful_update_affiliate_link | write | Change an affiliate link's token Change the token of an existing affiliate link. WARNING: the old token stops tracking immediately — links already shared with it break. Prefer rewardful_create_affiliate_link to add a second token. Rewardful: PUT /v1/affiliate_links/:id. |
rewardful_create_affiliate_coupon | write | Create an affiliate coupon Assign a coupon / promotion code to an affiliate so sales using it are credited to them. The code must match one defined in Stripe, and the affiliate's campaign must have a campaign coupon set in the dashboard. Rewardful: POST /v1/affiliate_coupons. |
rewardful_usage_status | Usage status (free-tier meter) Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter. | |
rewardful_request_feature | Request a missing feature Tell usefulapi that the user needs something the Rewardful tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. | |
rewardful_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Rewardful (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $19/month or $190/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter. | |
rewardful_cancel_subscription | Cancel the Pro subscription Cancel the caller's Rewardful Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run rewardful_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this Rewardful server only. Subscribe with rewardful_upgrade (it returns a Stripe Checkout link). Cancel any time with rewardful_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running rewardful_upgrade before then undoes the cancel. Or write to [email protected].
No. usefulapi is an independent service. It is not affiliated with or endorsed by Rewardful. The server calls the Rewardful API with your own Rewardful access, so it sees only the data that your account can see.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
The login page asks for your Rewardful API Secret. See Before you connect for where to find it.
No. 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: the login page asks for your Rewardful API Secret. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Rewardful API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Rewardful.
Yes, if you approve it. 7 of the 20 Rewardful tools can create or change data. The other 13 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls (fair use limit: 10,000 tool calls a month), for this Rewardful server only. Cancel any time: Pro then runs to the end of the paid period. Run rewardful_usage_status to see how many calls you used.
Ask the AI to run rewardful_upgrade: it returns a Stripe Checkout link. To cancel, run rewardful_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with rewardful_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
