Wise

@mindstone/mcp-server-wise

[npm version] [License: FSL-1.1-MIT]

Wise (formerly TransferWise) MCP server for Model Context Protocol hosts. Check multi-currency balances and exchange rates, review transactions and activity, manage recipients, price transfers with quotes — and, with an explicit opt-in, create, fund, and cancel transfers — all through a standardised MCP interface.

Status

• Version: 0.1.1 · npm
• Auth: API token (env var, or on disk via WISE_CONFIG_PATH)
• Tools: 17 (accounts, balances, recipients, quotes, transfers, discovery)
• Surface: cloud-api
• Machine-readable: STATUS.json

Requirements

• Node.js 20+
• npm
• A Wise API token: wise.com → Settings → API tokens

One-click install

[Add to Cursor] [Add to VS Code] [Add to VS Code Insiders]

After clicking the button, your host will prompt you to fill: WISE_API_TOKEN.

npx (once published)

npx -y @mindstone/mcp-server-wise

Local

node dist/index.js

Configuration

Environment variables

• WISE_API_TOKEN — Wise API token. Optional if you connect via the configure_wise tool instead; when set, it takes precedence over any stored token.
• WISE_ENVIRONMENT — production (default) or sandbox. Sandbox requires a token created in the Wise sandbox.
• WISE_CONFIG_PATH — path to the config directory that stores the token written by configure_wise (defaults to ~/.mcp/wise).
• WISE_REQUEST_TIMEOUT_MS — outbound request timeout in milliseconds (default 30000).
• MCP_HOST_BRIDGE_STATE — optional path to a host bridge state file used for credential management.
• MINDSTONE_REBEL_BRIDGE_STATE — backwards-compatible alias for MCP_HOST_BRIDGE_STATE.

Host configuration examples

{  "mcpServers": {    "Wise": {      "command": "npx",      "args": ["-y", "@mindstone/mcp-server-wise"],      "env": {        "WISE_API_TOKEN": "your-wise-api-token"      }    }  }}

Local development (no npm publish needed)

Tools (17)

Account management

• configure_wise — Connect a Wise account with an API token (verified against the Wise API before storing)
• remove_wise_account — Disconnect the Wise account

Profiles & balances

• list_wise_profiles — List personal and business profiles accessible with the token; use the ids as profile_id
• list_wise_balances — List balances (multi-currency accounts and savings jars) with amounts per currency
• get_wise_balance_statement — Transaction statement for one balance over a time window (max 469 days)
• list_wise_activities — Chronological activity feed (transfers, card payments, deposits) with status

Exchange rates & quotes

• get_wise_exchange_rate — Current or historic mid-market rate between two currencies
• create_wise_quote — Lock a rate and get exact fees per funding method (does not move money)

Recipients

• list_wise_recipients — List saved recipients (bank accounts), filterable by currency or type
• get_wise_recipient — Full details of one recipient, including bank details
• get_wise_recipient_requirements — Discover the bank detail fields Wise requires for a route, given a quote
• create_wise_recipient — Create a saved recipient (does not move money)

Transfers

• list_wise_transfers — List transfers with filters (status, currencies, created-date window)
• get_wise_transfer — Current state of one transfer
• create_wise_transfer — Create a transfer from a quote to a recipient (not funded yet)
• fund_wise_transfer — Fund a created transfer from a Wise balance (moves money)
• cancel_wise_transfer — Cancel a transfer before the funds_converted stage

Typical payout flow

1. list_wise_profiles → pick a profile_id
2. create_wise_quote — price the transfer and lock a rate
3. (New recipient) get_wise_recipient_requirements → create_wise_recipient
4. create_wise_transfer — creates the transfer (not funded yet)
5. fund_wise_transfer — pays from a Wise balance; this is the step that moves money

Security

• Money movement runs by default. create_wise_transfer, fund_wise_transfer, and cancel_wise_transfer are always available and declare destructiveHint: true — gating of individual invocations is the host's tool-approval layer's job, not the connector's. Quote and recipient creation never move money; only fund_wise_transfer debits a balance.
• Untrusted-content envelopes. Strings authored by external parties (recipient names and bank details, transfer references, statement descriptions and merchant names, activity titles, quote notices) are wrapped in <untrusted-content source="…"> envelopes so the host LLM treats them as data, not instructions. Connector-controlled metadata (ids, amounts, currencies, statuses, timestamps) is returned raw.
• Credential storage. Tokens written by configure_wise are stored in credentials.json under WISE_CONFIG_PATH with 0600 permissions (config directory 0700). Only the two fixed Wise hosts (api.wise.com, api.wise-sandbox.com) are ever contacted — there is no arbitrary base-URL override.
• Error hygiene. Vendor error bodies, raw Retry-After header text, and query-bearing URLs are never written to logs or surfaced in tool errors; tokens never appear in error messages.
• Idempotent transfer creation. create_wise_transfer uses customer_transaction_id as the Wise idempotency key, so a retry never creates a duplicate transfer.
• Input validation. Currency codes, numeric ids, UUIDs, and date-time windows are validated before any request is made.
