## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 18 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 73/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 3546 tokens (~168/item across 21 items; 18 tools + 3 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 13/100
  - Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 87/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 60% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 18 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 20 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

Signed-message verification (POST /wallets/{id}/verification then /verify) is optional and never required.

Input parameters:

- `address` (string): Checksummed EVM address, Solana pubkey or Tron address. Required when type=address.
- `address_type` (string)

- `limit` (integer): Page size (default 20).
- `status` (string)

### `create_webhook` (~162 tokens)

Create a webhook endpoint

Register a webhook endpoint. The response contains `secret` (whsec_...) ONCE: store it as COINVELLO_WEBHOOK_SECRET. Live endpoints must be HTTPS; test endpoints may be http://localhost. Use events ["*"] for everything or a list such as ["invoice.paid","invoice.expired"].

Input parameters:

- `description` (string)
- `enabled` (boolean)
- `events` (array, required): Event types or ["*"]. Common: invoice.paid, invoice.confirming, invoice.underpaid, invoice.overpaid, invoice.expired, payment.detected, checkout_session.completed.
- `metadata` (object): Up to 50 string key/value pairs returned on the object and in webhooks.

Implements the spec: HMAC-SHA256 over "<t>.<raw body>", 300 s tolerance, constant-time compare against any v1. Returns valid=true/false with the reason and the parsed event. Set ignore_timestamp=true when checking an old captured delivery.

Input parameters:

### `get_credits_balance` (~98 tokens)

Get processing-credit balance

Return the merchant's prepaid processing-credit balance: balance (= available + reserved, never negative), available (free to spend), reserved (estimated fees of open invoices paid with credits), low_balance_threshold, estimated_payments_remaining, auto_topup. There are no free live credits. 1 credit = $0.01 nominal; a confirmed payment consumes about 30 bps of its fiat value (floor 2, cap 2000).

### `list_credit_bundles` (~53 tokens)

List credit bundles

List purchasable credit bundles with USD price, price_per_credit and indicative crypto_prices per asset. Bigger bundles cost less per credit (effective rate ~0.30% down to <0.10%).

### `create_credit_purchase` (~199 tokens)

Buy credits (creates a crypto invoice)

Create a crypto credit purchase (cpu_...). Returns payment.payment_options with the address/amount to pay (CoinVello's operator wallet) and a hosted checkout_url. Credits are added when the payment confirms. Card purchases and automatic top-up are set up by the merchant in the dashboard, not through this tool. In test mode credits are free, so this is mainly for exercising the flow (pay it with simulate_test_payment).

Input parameters:

- `bundle_id` (string, required): From list_credit_bundles, e.g. bnd_growth_15000.
- `expires_in` (integer)
- `idempotency_key` (string)
- `metadata` (object): Up to 50 string key/value pairs returned on the object and in webhooks.
- `pay_asset` (string): Asset symbol to pay with, lowercase, e.g. usdt. Requires pay_chain. Omit for every option.
- `pay_chain` (string)

### `list_records` (~352 tokens)

List accounting records

List the account's book of record, newest first: one immutable row per movement of value (payment_received, fee_prepaid, credit_purchase, refund_sent, fee_onchain, conversion, offramp_payout...) valued when it happened. Each record has `value` (market value at the block time in the reporting currency, rate and source included), `value_usd`, `contract_value` (what the customer owed at the invoice's locked rate), `tax`, the on-chain proof (tx_hash, block_height, addresses, explorer_url) and an invoice snapshot. `currency` re-values from value_usd at the historical rate. With a test key, rows created by simulate_test_payment appear only with include_simulated=true. Returns { object: 'list', data, has_more, next_cursor }.

Input parameters:

- `asset` (string): Records whose received, sent or fee leg is this asset.
- `chain` (string)
- `currency` (string): Re-value `value` into this currency (default: the account's reporting currency).
- `cursor` (string): next_cursor from the previous page.
- `include_simulated` (boolean): Test mode only: include rows created by simulate_test_payment, which the sandbox hides by default. Ignored with a live key.
- `invoice_id` (string)
- `limit` (integer): Page size (default 20).
- `occurred_gte` (string): RFC 3339 timestamp; block time at or after.
- `occurred_lte` (string): RFC 3339 timestamp; block time at or before.
- `order_id` (string)
- `tx_hash` (string)
- `type` (string)

### `get_records_summary` (~257 tokens)

Get totals for a period

Sales (invoiced at the locked rates), received_market_value (what the coins were worth when they landed), valuation_difference, tax_collected, refunds, fees_prepaid and credits_consumed, fees_onchain, network_fees, credit_purchases and net_received, with payment counts, over occurred_at in the given timezone and currency. period_start is inclusive and period_end exclusive (a date such as 2026-01-01, or a date-time). group_by returns the same totals per month, asset, chain, type or address in `groups`. With a test key, simulated rows count only with include_simulated=true.

Input parameters:

- `currency` (string)
- `group_by` (string)
- `include_simulated` (boolean): Test mode only: include rows created by simulate_test_payment, which the sandbox hides by default. Ignored with a live key.
- `period_end` (string, required): Exclusive.
- `period_start` (string, required): Inclusive, read in `timezone`: a date (2026-01-01) or a date-time.
- `timezone` (string): IANA zone used to bucket occurred_at, e.g. Europe/Berlin. Default: the account's records timezone.

### `create_export` (~341 tokens)

Export records as CSV, Excel or JSON

Create an export of the records (default), another dataset, or `all` (the year-end package) for a period, or for the entire history when period is null or omitted. Returns the export object: small exports are already `ready` with `file` (name, content_type, bytes, sha256) and a signed `download_url` valid until `download_expires_at` (files are kept 7 days); while `queued` or `processing` call get_export. Vendor presets (quickbooks, xero, koinly, cointracker, coinledger) and journal need dataset=records and format=csv (otherwise 422). Verify the downloaded file against file.sha256. With a test key pass include_simulated=true to include simulated payments.

Input parameters:

- `currency` (string): Reporting currency of the value columns.
- `dataset` (string): Default records.
- `format` (string, required)
- `idempotency_key` (string): Stable key so a retry does not start a second export, e.g. records-2026-q3.
- `include_simulated` (boolean): Test mode only: include rows created by simulate_test_payment, which the sandbox hides by default. Ignored with a live key.
- `metadata` (object): Up to 50 string key/value pairs returned on the object and in webhooks.
- `period`: Read in `timezone`. Null or omitted exports the entire history.
- `preset` (string): Column layout for the records dataset (default generic).
- `timezone` (string): IANA zone, e.g. America/New_York. Default: the account's records timezone.

### `get_export` (~74 tokens)

Get an export

Retrieve an export (exp_...): status (queued, processing, ready, failed, expired), rows, file { name, content_type, bytes, sha256 }, download_url and download_expires_at, failure_reason. Poll after create_export until ready.

Input parameters:

- `id` (string, required): exp_... id from create_export

### `get_rates` (~65 tokens)

Get indicative exchange rates

Mid-market rates for supported assets against a fiat base (default USD). Indicative only; invoices lock their own rate at creation.

Input parameters:

- `assets` (array): Restrict to these asset ids.
- `base` (string): ISO 4217 code or asset id, default USD.

### `list_assets` (~145 tokens)

List supported assets

Every asset CoinVello accepts in the API key's mode: id (btc:bitcoin, usdc:polygon, eurc:base...), symbol, chain, kind (native/token), contract_address, decimals, required_confirmations, min_amount, testnet name and the wallet_type (xpub or address) needed to accept it. Tokens without a testnet contract (DAI, usdc:bnb, usdt on base/arbitrum/optimism/avalanche/solana, and the Bitcoin tokens wbtc/cbbtc/btcb) are live-only, so a test key does not list them.

Input parameters:

- `chain` (string): Filter by chain.

### `simulate_test_payment` (~177 tokens)

Simulate a payment (test mode)

Create a synthetic on-chain payment for an invoice (inv_) or credit purchase (cpu_) and run it through the real state machine and webhook pipeline. Test keys only. confirmations=0 -> payment.detected / invoice.pending; confirmations >= required -> invoice.paid. Use a smaller/larger amount to simulate underpaid/overpaid. Reuse tx_hash to advance the same payment.

Input parameters:

- `amount` (string): Amount in the asset; defaults to the exact payment_options[].amount.
- `asset` (string): Which payment option to pay; defaults to the first accepted asset.
- `confirmations` (integer): Default 0 (detected only).
- `delay_seconds` (integer)
- `from_address` (string)
- `invoice_id` (string, required): inv_... or cpu_...
- `tx_hash` (string)

## Common questions

### What is the CoinVello MCP server?

CoinVello is an MCP server listed in the public MCP registry as io.github.CoinVello/coinvello. Non-custodial crypto payments: checkout sessions, invoices, webhooks and test payments. No KYC. This page covers its hosted endpoint (https://mcp.coinvello.com/mcp).

### Is the CoinVello MCP server safe to use?

CoinVello scores 67 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the CoinVello MCP server expose?

CoinVello exposes 18 tools: create_checkout_session, get_invoice, list_invoices, list_payments, create_wallet, and 13 more. Their descriptions and schemas cost roughly 3,241 tokens of context every time the server is loaded.

### Does the CoinVello MCP server require authentication?

No. We connected to CoinVello without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the CoinVello MCP server still maintained?

CoinVello is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the CoinVello MCP server?

VerifyMCP ran 12 checks on CoinVello, covering TLS certificate, HTTPS, HSTS header, DNSSEC and 8 more. One item could not be completed, a gap on our side rather than a finding about CoinVello: Authorization. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
