What you can do with PagSafe in Claude and ChatGPT

For Brazilian online sellers who take Pix payments and run Pix Automático subscriptions.

Create a Pix charge and send the payment code

Create a one-time Pix charge for an order and copy the payment code to the buyer. The charge is paid only after the PagSafe webhook reports AUTHORIZED.

Changes data

Check whether a payment has cleared

Read the current status of a transaction, such as PENDING or AUTHORIZED. Use it to check a payment or to recover a missed webhook.

Refund a transaction in full

Refund the full amount of an authorized transaction to the buyer. A refund cannot be undone, so check the transaction status first.

Changes data

Start a recurring Pix Automático subscription

Create a recurring Pix Automático subscription and show its QR code or payment link to the buyer. The buyer authorizes it once.

Changes data

Check or cancel a customer subscription

Read the status and next charge date of a subscription. Cancel it to stop further cycles; the buyer keeps access until the paid cycle ends.

How do I connect PagSafe?

Before you connect

The login page asks for your PagSafe API key (x-api-key) and PagSafe API secret (x-api-secret).

Find them in PagSafe → Integrações → API → Nova credencial. Your key pair is used only to call the API on your behalf and to derive a private account id; it is never shown to anyone.

Claude claude.ai · Desktop

Open Customize → Connectors, then click + Add → Add custom connector.
Enter the name PagSafe and this URL, then click Add:
https://pagsafe.usefulapi.io/mcp
Claude opens the login page: enter your PagSafe API key (x-api-key) and PagSafe API secret (x-api-secret).
In a chat, click + → Connectors and turn on PagSafe.

Team and Enterprise: an Owner adds the connector for the organization first.

ChatGPT chatgpt.com

Open Plugins, click +, then Add custom MCP server.
Enter the name PagSafe and this URL, choose OAuth as the authentication, confirm the warning and create it:
https://pagsafe.usefulapi.io/mcp
ChatGPT opens the login page: enter your PagSafe API key (x-api-key) and PagSafe API secret (x-api-secret).
In Plugins, install PagSafe, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http pagsafe https://pagsafe.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "pagsafe": {
      "url": "https://pagsafe.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "pagsafe": {
      "type": "http",
      "url": "https://pagsafe.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add pagsafe --url https://pagsafe.usefulapi.io/mcp

codex mcp login pagsafe

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.

https://pagsafe.usefulapi.io/mcp

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 PagSafe API key (x-api-key) and PagSafe API secret (x-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 PagSafe server only. Ask your AI to run pagsafe_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 pagsafe_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 pagsafe_upgrade before then undoes the cancel. Or write to [email protected].

Read only · 2

Get a transactionpagsafe_get_transaction
Get the current status of a transaction created through this API: PENDING, AUTHORIZED (paid), FAILED, REFUNDED, IN_DISPUTE or CHARGEBACK. Use it to check a payment or to recover a lost webhook; prefer the webhook for live updates. Uses GET /v2/transactions/{transaction_id}.
Get a subscriptionpagsafe_get_subscription
Get a subscription's status (PENDING_AUTHORIZATION, ACTIVE, LATE, PAUSED or CANCELED), amount, cycle, and the dates of the last and next charge. Uses GET /v2/subscriptions/{subscription_id}.

Changes data · 4

Create a Pix chargepagsafe_create_pix_charge
Create a one-time Pix charge. Returns the id, status PENDING, and pix.payload (the copy and paste code to show the buyer). The charge is paid only when the PagSafe webhook reports AUTHORIZED: do not treat the reply as paid. A retry with the same external_id, amount and customer.document returns the same pending Pix within 6 hours (reused: true). Writes a real charge. Uses POST /v2/transactions.
Refund a transactionpagsafe_refund_transaction
Refund the full amount of a transaction back to the buyer. The transaction must be AUTHORIZED, created through this API, and have enough balance in every split account. A refund cannot be undone. Uses POST /v2/transactions/{transaction_id}/refund.
Create a Pix Automático subscriptionpagsafe_create_pix_subscription
Create a recurring Pix Automático subscription. Returns status PENDING_AUTHORIZATION and pix.qr_code or pix.payment_link: show one to the buyer, who must authorize it once. After authorization the status becomes ACTIVE and later cycles are charged on their own. For Pix, the cycles are SEMANAL, MENSAL and ANUAL only. If the call fails with HTTP 500, check PagSafe for an existing subscription before you retry. Writes a real subscription. Uses POST /v2/subscriptions.
Cancel a PagSafe subscriptionpagsafe_cancel_pix_subscription
Cancel a PagSafe customer subscription so no further cycles are charged. The buyer keeps access until the cycle already paid ends. This cancels a subscription of YOUR customer, not a UsefulAPI plan. Uses POST /v2/subscriptions/{subscription_id}/cancel.

Your usefulapi plan · 4

Usage status (free-tier meter)pagsafe_usage_status
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.
Request a missing featurepagsafe_request_feature
Tell usefulapi that the user needs something the PagSafe 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+pagsafe_upgrade
Get a paid plan for PagSafe (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 (needs confirm: true; the price difference for the rest of the period is charged at once). 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 subscriptionpagsafe_cancel_subscription
Cancel the caller's PagSafe 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 pagsafe_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with PagSafe in Claude or ChatGPT?

Create a Pix charge and send the payment code. Check whether a payment has cleared. Refund a transaction in full. Start a recurring Pix Automático subscription. Check or cancel a customer subscription. See what you can do for the details.

Is this an official PagSafe product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by PagSafe. The server calls the PagSafe API with your own PagSafe access, so it sees only the data that your account can see.

Can I connect PagSafe 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 PagSafe API key (x-api-key) and PagSafe API secret (x-api-secret). See Before you connect for where to find them.

Do I put my PagSafe 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 PagSafe API key (x-api-key) and PagSafe API secret (x-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 PagSafe credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the PagSafe 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 PagSafe.

Can the AI change my PagSafe data?

Yes, if you approve it. 4 of the 6 PagSafe tools can create or change data. The other 2 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 PagSafe server only. Cancel any time: your paid plan then runs to the end of the paid period. Run pagsafe_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run pagsafe_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 pagsafe_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a PagSafe tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with pagsafe_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.
