// key findings

⚠️

Known vulnerabilities in dependencies: 3 high

Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.

✅

20 tools verified — handlers match their declared behaviour

14 read-only tools verified — handlers contain no write/delete/exec

✅

No credential exfiltration, no sensitive file access, no obfuscation

Static analysis found nothing flowing your secrets to unexpected places.

🔐

You'll be asked for 1 credential: WISE_API_TOKEN

These are read from process.env at runtime. Make sure you trust where they’ll be sent.

// tools this server exposes20 tools

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

list_balances

List all balance accounts for a profile. Returns currency balances with available amounts. Types: STANDARD (one per currency) or SAVINGS (jars, multiple per currency).

get_balance

Get a specific balance account by ID

list_profiles

List all profiles (personal and business) associated with your Wise account

get_profile

Get a specific profile by ID

create_quote

Create a quote for a money transfer. Specify either sourceAmount OR targetAmount (not both). Returns exchange rate, fees, and delivery estimate.

get_quote

Get an existing quote by ID

get_temporary_quote

Get a temporary (non-stored) quote to check rates and fees without creating one

get_exchange_rate

Get the current exchange rate between two currencies

get_exchange_rate_history

Get historical exchange rates between two currencies over a time period

list_recipients

List all recipient accounts for a profile, optionally filtered by currency

get_recipient

Get a specific recipient account by ID

create_recipient

Create a new recipient account. The 'details' object varies by currency/type. Use get_account_requirements first to know which fields are needed.

delete_recipient

Delete (deactivate) a recipient account

get_account_requirements

Get the required fields for creating a recipient in a specific currency route. Returns field definitions with validation rules.

list_transfers

List transfers for a profile with optional filters

get_transfer

Get a specific transfer by ID

create_transfer

Create a new transfer. Requires a quote ID and recipient account ID. The customerTransactionId ensures idempotency — reuse the same value when retrying a failed request to avoid duplicate transfers. NOTE: In EU/UK, funding from balance via personal token is restricted by PSD2.

fund_transfer

Fund a transfer from your Wise balance. NOTE: This may NOT work with personal tokens in EU/UK due to PSD2 regulations.

cancel_transfer

Cancel a transfer (only possible if not yet completed)

get_delivery_estimate

Get the estimated delivery date for a transfer

// quality suggestions

All four hints declared on every tool

14/20 tools missing one or more hints — list_balances (missing: idempotentHint); get_balance (missing: idempotentHint); list_profiles (missing: idempotentHint), +11 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool inputs are validated

19/20 tool handlers declare input schemas (95%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tool handlers catch errors

Only 0/20 tool handlers wrap calls in try/catch (0%)

Wrap each tool handler body in try/catch and return a structured error response.

License file

No license file

Add a LICENSE file (MIT, Apache-2.0, etc.).

Tests exist

No test files found

Add tests that exercise each declared tool.

Production dependencies are patched

0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.1 (high), @modelcontextprotocol/sdk@1.12.1 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// full audit trail

The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.

// improvement guidance — verified publishers only

We have 6 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
