Common questions

Is MCP Unblockpay safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: UNBLOCKPAY_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 2 months ago, and the latest version (0.3.1) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@codespar/mcp-unblockpay

MCP server for UnblockPay — fiat ↔ stablecoin cross-border via Customer → Wallet → Quote → Payin/Payout

Quick Start

Claude Desktop

Add to ~/.config/claude/claude_desktop_config.json:

"mcpServers": { "unblockpay": { "command": "npx", "args": ["-y", "@codespar/mcp-unblockpay"], "env": { "UNBLOCKPAY_API_KEY": "your-key" } } } }

Claude Code

claude mcp add unblockpay -- npx @codespar/mcp-unblockpay

Cursor / VS Code

Add to .cursor/mcp.json or .vscode/mcp.json:

"servers": { "unblockpay": { "command": "npx", "args": ["-y", "@codespar/mcp-unblockpay"], "env": { "UNBLOCKPAY_API_KEY": "your-key" } } } }

Tools (13)

Tool	Purpose
`create_customer`	Create an individual or business customer (KYC mother). Business customers require `date_of_incorporation`.
`list_customers`	List customers under the operator's API key (`limit` mandatory by the v1 pagination contract).
`verify_customer`	Trigger the KYC verification check. Idempotent (returns 422 `customer_cannot_be_verified` when already approved).
`get_verification_details`	Poll KYC state — returns `customer_status: pending \	approved \	rejected \	partially_rejected`.
`create_wallet`	Create a stablecoin wallet under an APPROVED customer.
`list_wallets`	List wallets under the operator's API key.
`create_external_account`	Register a fiat receiver account (BRL Pix, USD wire, EUR SEPA, MXN SPEI). Skippable for BRL Pix payouts via the `pix_key + document` shortcut on `create_payout`.
`list_external_accounts`	List external accounts under the operator's API key.
`create_quote`	Lock an FX + fee quote for 5 minutes. Pass `amount` on EITHER `sender` or `receiver`, not both.
`create_payin`	Fiat → stablecoin pay-in referencing a `quote_id`. Returns deposit instructions ( for BR).
`create_payout`	Stablecoin → fiat payout referencing a `quote_id`. `customer_id` is REQUIRED at the top level.
`get_transaction`	Poll transaction status. Lifecycle: `awaiting_deposit → processing → completed` (or `failed / refunded / cancelled / error`).
`cancel_transaction`	Cancel a transaction. Only valid while status is `awaiting_deposit`.

Authentication

UnblockPay uses an API key passed verbatim in the Authorization header (no Bearer prefix). The server sets that header for you — you just provide the key via UNBLOCKPAY_API_KEY.

Sandbox / Testing

UnblockPay provides a separate sandbox environment for testing. Point the server at it by setting UNBLOCKPAY_BASE_URL=https://api.sandbox.unblockpay.com/v1 and using a sandbox-issued API key.

Get your credentials

Sign in at app.unblockpay.com (or follow the docs)
Generate an API key in the dashboard
Set the UNBLOCKPAY_API_KEY environment variable
(Sandbox only) Also set UNBLOCKPAY_BASE_URL=https://api.sandbox.unblockpay.com/v1

Environment Variables

Variable	Required	Description
`UNBLOCKPAY_API_KEY`	Yes	API key from the UnblockPay dashboard
`UNBLOCKPAY_BASE_URL`	No	Defaults to `https://api.unblockpay.com/v1`. Set to `https://api.sandbox.unblockpay.com/v1` for sandbox.

Roadmap

The 13 tools above mirror UnblockPay's current v1 API. New tools are added as UnblockPay expands the surface.
