Read products, sales, subscribers and offer codes; verify, enable and disable product licenses. For creators who sell digital products and memberships on Gumroad. 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": {
"gumroad": {
"url": "https://gumroad.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"gumroad": {
"type": "http",
"url": "https://gumroad.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 AI lists your successful sales with date, email and product or order filters, newest first. It can total them by product so you see what sold.
gumroad_list_sales gumroad_get_sale gumroad_list_products
The AI checks that a license key is valid for a product and shows the purchase details. By default it does not count a use; it can also record one use.
Changes data · gumroad_verify_license
The AI lists a product's offer codes, creates a new discount code, or changes the code text or the max purchase count of an existing one.
Changes data · gumroad_list_offer_codes gumroad_create_offer_code gumroad_update_offer_code
The AI lists the subscribers of a membership product, or finds one by buyer email, and reads one subscriber in detail.
gumroad_list_products gumroad_list_subscribers gumroad_get_subscriber
The AI enables a product so it can be sold, or disables it so it can no longer be sold. You can also have it turn a product's license key on or off.

The login page asks for your Gumroad access token.
Create one in Gumroad → Settings → Advanced → Applications, then generate an access token. Your access token is used only to call the 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 Gumroad access 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.
Turn on the Gumroad connector, then ask in plain words. The AI picks the tools.

gumroad_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. | |
gumroad_request_feature | Request a missing feature Tell usefulapi that the user needs something the Gumroad 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. | |
gumroad_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Gumroad (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+, $39/month or $390/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. | |
gumroad_cancel_subscription | Cancel the Pro subscription Cancel the caller's Gumroad 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 gumroad_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 |
| Pro | $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 Gumroad server only. Subscribe with gumroad_upgrade (it returns a Stripe Checkout link). Cancel any time with gumroad_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running gumroad_upgrade before then undoes the cancel. Or write to [email protected].
Look up sales by date, product or buyer email. Check a license key or record a use. Create or change an offer code. Review the subscribers of a membership product. Publish or unpublish products; enable or disable licenses. See what you can do for the details.
No. usefulapi is an independent service. It is not affiliated with or endorsed by Gumroad. The server calls the Gumroad API with your own Gumroad 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 Gumroad access token. 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 Gumroad access 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.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Gumroad 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 Gumroad.
Yes, if you approve it. 7 of the 20 Gumroad 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 Gumroad server only. Cancel any time: Pro then runs to the end of the paid period. Run gumroad_usage_status to see how many calls you used.
Ask the AI to run gumroad_upgrade: it returns a Stripe Checkout link. To cancel, run gumroad_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 gumroad_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.
