What you can do with Rewardful in Claude and ChatGPT

The AI lists affiliates with visitor, lead and conversion counts, by campaign or looked up by email, and opens one affiliate for links and coupon.

Check payouts and the commissions in them
The AI lists payouts by affiliate or state (pending, due, processing, paid) and opens one to see the commissions it bundles.
Trace referrals from visitor to conversion
The AI lists referrals filtered by affiliate, state, email or Stripe customer, with the link and conversion state of each.
Review, create or update campaign reward rules
The AI lists campaigns with commission rules, payout minimum and referral expiry. It creates a campaign or changes one.
Changes dataAdd or update an affiliate, add a link or coupon
The AI adds an affiliate, changes an affiliate's name, email, campaign or state, gives one an extra tracking link, or assigns a coupon code.
Changes dataHow do I connect Rewardful?
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.

Claude Code
Run this command, then run /mcp in Claude Code to log in:
Cursor
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"rewardful": {
"url": "https://rewardful.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"rewardful": {
"type": "http",
"url": "https://rewardful.usefulapi.io/mcp"
}
}
} Codex
Run these commands. The second one opens the login page:
Other clients
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
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.
Pricing
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per user | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this Rewardful server only. Ask your AI to run rewardful_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with rewardful_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with rewardful_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4
- Usage status (free-tier meter)
rewardful_usage_statusReport 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. - Request a missing feature
rewardful_request_featureTell 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. - Upgrade to Pro or Pro+
rewardful_upgradeGet a paid plan for Rewardful (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter. - Cancel the Pro subscription
rewardful_cancel_subscriptionCancel 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.
FAQ
What can I do with Rewardful in Claude or ChatGPT?
See how your affiliates perform. Find the commissions you still owe. Check payouts and the commissions in them. Trace referrals from visitor to conversion. Review, create or update campaign reward rules. Add or update an affiliate, add a link or coupon. See what you can do for the details.
Is this an official Rewardful product?
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.
Can I connect Rewardful to Claude or ChatGPT?
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.
What do I need to connect?
The login page asks for your Rewardful API Secret. See Before you connect for where to find it.
Do I put my Rewardful key or an Authorization header in the client config?
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.
How do you keep my Rewardful credentials?
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.
Can the AI change my Rewardful data?
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.
What does it cost?
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Rewardful server only. Cancel any time: your paid plan then runs to the end of the paid period. Run rewardful_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run rewardful_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run rewardful_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a Rewardful tool that I need is missing?
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.
Which AI clients can I use?
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.
