What you can do with ReferralHero in Claude and ChatGPT
For marketers who run referral and giveaway campaigns with ReferralHero.
Show the leaderboard of a campaign
The AI reads the top 10 to 100 subscribers of a campaign with referral counts, points and position. It can also list your campaigns with their subscriber counts.
Find a subscriber and see who they referred
The AI finds a subscriber by email, referral code or name, reads their points, position and fraud risk level, and lists the people they referred.
Check which rewards are pending or sent
The AI lists the rewards unlocked across a campaign with status (sent, resent, canceled, pending, flagged), value and subscriber, and the reward setup of the campaign.
Add subscribers, points or purchases
The AI adds a subscriber to a campaign, adds points to one, or records a purchase for a subscriber so revenue-based rewards count it. Each points call adds again.
Changes dataQualify referrals and update reward status
The AI marks a referral as qualified or unqualified, for example after fraud or a refund, and sets an unlocked reward to sent, resent or canceled. Marking sent can email the subscriber.
Changes dataHow do I connect ReferralHero?
Before you connect
The login page asks for your ReferralHero API token.
Find it in ReferralHero → Account → API. The token gives access to every campaign in the account. Your token is used only to call the ReferralHero API on your behalf; 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": {
"referralhero": {
"url": "https://referralhero.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"referralhero": {
"type": "http",
"url": "https://referralhero.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 ReferralHero API token. 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 ReferralHero server only. Ask your AI to run referralhero_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 referralhero_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 referralhero_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4
- Usage status (free-tier meter)
referralhero_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
referralhero_request_featureTell usefulapi that the user needs something the ReferralHero 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+
referralhero_upgradeGet a paid plan for ReferralHero (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
referralhero_cancel_subscriptionCancel the caller's ReferralHero 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 referralhero_upgrade later to undo the cancel before the period ends. Does not count against the meter.
FAQ
What can I do with ReferralHero in Claude or ChatGPT?
Show the leaderboard of a campaign. Find a subscriber and see who they referred. Check which rewards are pending or sent. Add subscribers, points or purchases. Qualify referrals and update reward status. See what you can do for the details.
Is this an official ReferralHero product?
No. usefulapi is an independent service. It is not affiliated with or endorsed by ReferralHero. The server calls the ReferralHero API with your own ReferralHero access, so it sees only the data that your account can see.
Can I connect ReferralHero 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 ReferralHero API token. See Before you connect for where to find it.
Do I put my ReferralHero 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 ReferralHero API token. 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 ReferralHero credentials?
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the ReferralHero 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 ReferralHero.
Can the AI change my ReferralHero data?
Yes, if you approve it. 15 of the 28 ReferralHero 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 ReferralHero server only. Cancel any time: your paid plan then runs to the end of the paid period. Run referralhero_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run referralhero_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 referralhero_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a ReferralHero tool that I need is missing?
Tell the AI what you wanted to do. It can send the request with referralhero_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.
