Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-06 (score 68, +1)

No change was recorded against any check on this day. Stability & Change Management went from 33 to 37. That category is still filling its 30-day observation window: 10 days of observed history at the previous scan, 11 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (13)

### `create_customer` (~243 tokens)

Create an individual or business customer (KYC mother). Business customers require date_of_incorporation; both types use 3-letter ISO country codes (BRA/USA/MEX). Returns { id, status: 'pending', verification: { verification_link } }.

Input parameters:

- `address` (object)
- `business_legal_name` (string): Required when type=business
- `country` (string, required): 3-letter ISO 3166-1 alpha-3 country code (BRA, USA, MEX)
- `date_of_birth` (string): ISO date (YYYY-MM-DD). Required when type=individual
- `date_of_incorporation` (string): ISO date (YYYY-MM-DD). REQUIRED when type=business
- `email` (string)
- `first_name` (string): Required when type=individual
- `last_name` (string): Required when type=individual
- `phone_number` (string): E.164 format, e.g. +5511999999999
- `tax_id` (string): CNPJ for BRA business, EIN for USA, RFC for MEX, etc.
- `type` (string, required): Customer type

### `list_customers` (~53 tokens)

List customers under the operator's API key. `limit` is mandatory per UnblockPay's pagination contract.

Input parameters:

- `limit` (number, required): Required by the API (1-100)
- `offset` (number)

### `verify_customer` (~66 tokens)

Trigger the KYC verification check for a customer. Sandbox auto-progresses business customers through the hosted KYC flow once documents are uploaded. Idempotent — returns 422 'customer_cannot_be_verified' when already approved (safe to ignore).

Input parameters:

- `id` (string, required): Customer ID

### `get_verification_details` (~59 tokens)

Poll the KYC verification state for a customer. Returns { customer_status: 'pending' | 'approved' | 'rejected' | 'partially_rejected', verification_steps: [...] }.

Input parameters:

- `id` (string, required): Customer ID

### `create_wallet` (~103 tokens)

Create a stablecoin wallet under an APPROVED customer. blockchain selects the network (solana → USDC; ethereum/polygon → USDC/USDT; tron → USDT). Customer must be 'approved' before this succeeds (422 customer_not_allowed otherwise).

Input parameters:

- `blockchain` (string, required)
- `customer_id` (string, required)
- `is_external_wallet` (boolean): False for UnblockPay-managed wallets
- `name` (string, required): Human-readable wallet name

### `list_wallets` (~32 tokens)

List wallets under the operator's API key.

Input parameters:

- `limit` (number)
- `offset` (number)

### `create_external_account` (~95 tokens)

Register a fiat receiver account (BRL Pix, USD wire, EUR SEPA, MXN SPEI). Skippable for BRL Pix payouts — pass pix_key + document directly on /payout instead.

Input parameters:

- `currency` (string, required): BRL / USD / MXN / EUR
- `customer_id` (string, required)
- `payment_rail` (string, required): pix / us_wire / spei / sepa

### `list_external_accounts` (~33 tokens)

List external accounts under the operator's API key.

Input parameters:

- `limit` (number)
- `offset` (number)

### `create_quote` (~93 tokens)

Lock an FX + fee quote for a 5-minute TTL. Same endpoint for both on_ramp (fiat → stablecoin) and off_ramp (stablecoin → fiat). Pass amount on EITHER sender or receiver, not both. Response carries { id, expires_at, commercial_quotation, fees }.

Input parameters:

- `receiver` (object, required)
- `sender` (object, required)
- `type` (string, required)

### `create_payin` (~100 tokens)

Create a fiat → stablecoin pay-in referencing a quote_id. Sandbox min: 150 BRL / payout-side equivalents. Response carries { id, status: 'awaiting_deposit', sender_deposit_instructions: { deposit_address: '<Pix Copy & Paste EMV>' }, transaction_link }.

Input parameters:

- `customer_id` (string, required)
- `quote_id` (string, required)
- `receiver` (object, required)
- `sender` (object, required)

### `create_payout` (~151 tokens)

Create a stablecoin → fiat payout referencing a quote_id. customer_id is REQUIRED at the top level (404 'Customer not found' otherwise). Pix-BR shortcut: pass receiver.pix_key + receiver.document directly to skip external_account registration. Sandbox min: 25 USDC. Response carries { id, status: 'awaiting_deposit', transaction_link, sender_deposit_instructions: { deposit_address: '<blockchain address>' } }.

Input parameters:

- `customer_id` (string, required)
- `quote_id` (string, required)
- `receiver` (object, required): EITHER { pix_key, document } for BRL Pix shortcut OR { external_account_id } for other currencies
- `sender` (object, required)

### `get_transaction` (~69 tokens)

Poll transaction status. Lifecycle: awaiting_deposit → processing → completed (or failed / refunded / cancelled / error). Sandbox does NOT auto-progress without a webhook simulation — see UnblockPay's /concepts/transactions docs for the mocked transaction IDs available for status testing.

Input parameters:

- `id` (string, required)

### `cancel_transaction` (~61 tokens)

Cancel a transaction. Only valid while status is 'awaiting_deposit' — UnblockPay's API returns 422 once the deposit has been received.

Input parameters:

- `id` (string, required)
- `status` (string, required): Set to 'cancelled' to abort
