Fin Codes API

Fin Codes API MCP server

Connect your AI assistant to banking reference data, payee-name verification, and sanctions screening.

Hosted endpoint: https://mcp.fincodesapi.com/mcp

Transport: Streamable HTTP

Homepage and setup: https://fincodesapi.com/mcp-server

Official registry: com.fincodesapi/fincodesapi

This repository contains public connector configuration and documentation for the hosted service. It does not contain the proprietary backend, run a local server, or publish an npm, PyPI, or Docker package.

Connect

Add the endpoint as a remote HTTP MCP server in your client, then sign in to your Fin Codes API account through OAuth. Sign up at https://fincodesapi.com/sign-up if needed. OAuth-aware clients do not need a manually created API key.

Claude Code

claude mcp add --transport http fincodesapi https://mcp.fincodesapi.com/mcp

Run /mcp to sign in. In Claude Desktop or claude.ai, add the endpoint as a custom connector.

VS Code

Add to .vscode/mcp.json, then start the server and sign in:

{"servers":{"fincodesapi":{"type":"http","url":"https://mcp.fincodesapi.com/mcp"}}}

Cursor and other MCP clients

Add the remote endpoint in the client's MCP settings. The included mcp.json defines the connection; plugin.json is a portable Agent Plugins manifest. Client support and OAuth setup vary.

Cline

In Cline, open MCP Servers → Remote Servers, add the endpoint above, and choose Streamable HTTP. Complete OAuth authorization when prompted. If using JSON configuration, use Cline's transport spelling:

{"mcpServers":{"fincodesapi":{"type":"streamableHttp","url":"https://mcp.fincodesapi.com/mcp","disabled":false,"autoApprove":[]}}}

If OAuth is unavailable in your client version, create your own API token at https://fincodesapi.com/api-keys and add an Authorization: Bearer YOUR_API_KEY header locally. Keep the key out of shared files. Confirm that eleven tools appear and try looking up BSB 082-024.

See Cline's MCP documentation. Cline installation of this connector has not yet been independently tested.

Gemini CLI

gemini extensions install https://github.com/swiftcodesapi/fincodesapi-mcp

Run /mcp auth fincodesapi if prompted to sign in. The extension uses HTTP transport and OAuth discovery.

API-key clients

Clients without OAuth can use an API key created at https://fincodesapi.com/api-keys. Send Authorization: Bearer YOUR_API_KEY to the same endpoint. Store your real key in the client's secret store; never commit it to this repository.

Eleven tools

Tool	Purpose
lookup_iban	Validate an IBAN and return bank, country, and BIC/SWIFT details
verify_iban_payee	Compare a supplied payee name with the holder of a supported European IBAN
lookup_bic	Resolve BIC/SWIFT bank and branch details
lookup_us_routing_number	Look up a US ABA routing number
lookup_canada_routing_number	Look up a Canadian routing number
lookup_australia_bsb	Look up an Australian BSB
lookup_new_zealand_bank_code	Look up a New Zealand bank and branch code
lookup_india_ifsc	Look up an Indian IFSC
lookup_mexico_clabe	Validate a Mexican CLABE and identify its bank
lookup_argentina_cbu	Validate an Argentine CBU and identify its bank
screen_sanctions	Screen a name against EU, UK, UN, OFAC, Swiss, Australian and Canadian sanctions lists

Live MCP tool schemas are authoritative.

Examples

• “Validate DE57 1001 0010 0593 9081 19 and tell me its bank and BIC.”
• “Which bank and branch does Australian BSB 082-024 identify?”
• “Run the documented free payee verification fixture: does DE75512108001245126199 match John Doe?”
• “Screen the name Sadam Husein with a minimum match score of 95.”

The John Doe/IBAN pair is a documented test fixture. Its response does not establish real account ownership. Bank-code validity alone does not establish account existence or ownership. Sanctions name similarity requires review and does not establish identity or sanctioned status. The tools do not transfer money, execute trades, reverse-search private accounts by name, or determine creditworthiness.

Account and pricing

A Fin Codes API account is required. Lookups consume the account's plan quota; payee checks consume prepaid Verification of Payee credits. Plans and credits are purchased on https://fincodesapi.com/pricing. The connector does not process purchases or payments. A trial is available; current terms and limits are shown on the website.
