What you can do with Referral Rock in Claude and ChatGPT
For marketers and customer teams who run referral programs with Referral Rock.
Find your top referrers
The AI lists members with referral counts and rewards earned, and reads one member's views, shares, pending, qualified and approved referrals over a period.
Check which referrals are pending
The AI lists referrals filtered by program and status (pending, qualified, approved, denied), with the referring member and dates, and opens one.
See how much you owe in reward payouts
The AI lists pending payouts with recipient and total amount, and the payout transactions already sent with the balance left to cover them.
Review programs and their reward rules
The AI lists programs with their offers and share URLs and reads the reward rules of one: the trigger, fixed or percent amount, and payout type.
Add a member, or add or update a referral
The AI adds a member to a program, adds a referral for a member's code, or updates a referral's status, amount or notes. A qualified or approved status can trigger rewards.
Changes dataHow do I connect Referral Rock?
Before you connect
The login page asks for your Public API key and Private API key.
Create them in Referral Rock → Integrations → API Keys (app.referralrock.com/clientadmin/integrations/apikeys). The private key is shown only once, right after you generate it. The keys act as an admin of your account; use a dedicated key pair so you can revoke it later. They are used only to call the Referral Rock API on your behalf and are 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": {
"referral-rock": {
"url": "https://referral-rock.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"referral-rock": {
"type": "http",
"url": "https://referral-rock.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 Public API key and Private API key. 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 Referral Rock server only. Ask your AI to run referralrock_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 referralrock_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 referralrock_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

- Add a member to a program
referralrock_create_memberWRITE: creates a new member (advocate) in a referral program and returns the member with their referral code and share URL. Not idempotent: a repeat call may create a duplicate or fail. When send_confirmation_email is true Referral Rock emails the member the program's confirmation email, which is a message to a real person; the default is false. - Update a member
referralrock_update_memberWRITE: changes contact details of an existing member, or disables / re-enables the member (a disabled member can no longer take part in the programs). Only the fields you pass are changed. The member is found by id, referral code, or email / external id plus program_id or program_name; Referral Rock updates it only when it is uniquely identified. - Add a referral
referralrock_create_referralWRITE: adds a referral (a lead) to the program of the member who owns the given referral code, as if the lead had used that member's link. A status of qualified or approved can trigger the program's configured rewards for the member, which is a financial commitment, so leave status out (new referrals start as pending) unless you mean it. Not idempotent. - Update a referral (status, amount, notes)
referralrock_update_referralWRITE: changes the status, amount or notes of an existing referral. Moving a referral to qualified or approved can trigger the program's configured rewards for the referring member (a financial commitment that may be paid out automatically), and denied stops them: confirm with the user first. Only the fields you pass are changed. The referral is found by id, or by external id / email plus program_id or program_name. - Record a customer purchase
referralrock_record_customerWRITE: reports a paying customer to Referral Rock. A customer whose email matches a pending referral turns that referral to approved, which triggers the program's configured rewards for the referring member (a financial commitment that may be paid out automatically). A customer with no matching referral is added as a pre-loaded member to every program that has Preload New Customers on. Returns the outcome per customer (ReferralApproved, MemberPreloaded, Skipped…). Not idempotent.
Your usefulapi plan · 4
- Usage status (free-tier meter)
referralrock_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
referralrock_request_featureTell usefulapi that the user needs something the Referral Rock 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+
referralrock_upgradeGet a paid plan for Referral Rock (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
referralrock_cancel_subscriptionCancel the caller's Referral Rock 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 referralrock_upgrade later to undo the cancel before the period ends. Does not count against the meter.
FAQ
What can I do with Referral Rock in Claude or ChatGPT?
Find your top referrers. Check which referrals are pending. See how much you owe in reward payouts. Review programs and their reward rules. Add a member, or add or update a referral. See what you can do for the details.
Is this an official Referral Rock product?
No. usefulapi is an independent service. It is not affiliated with or endorsed by Referral Rock. The server calls the Referral Rock API with your own Referral Rock access, so it sees only the data that your account can see.
Can I connect Referral Rock 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 Public API key and Private API key. See Before you connect for where to find them.
Do I put my Referral Rock 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 Public API key and Private API key. 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 Referral Rock credentials?
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Referral Rock 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 Referral Rock.
Can the AI change my Referral Rock data?
Yes, if you approve it. 5 of the 15 Referral Rock tools can create or change data. The other 10 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 Referral Rock server only. Cancel any time: your paid plan then runs to the end of the paid period. Run referralrock_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run referralrock_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 referralrock_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a Referral Rock tool that I need is missing?
Tell the AI what you wanted to do. It can send the request with referralrock_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.
