## Documentation

## What openfang-rail does

The openfang-rail MCP server exposes deterministic validation and fraud-checking capabilities through the Model Context Protocol. Its stated scope covers five areas: IBAN checks, LEI checks, VAT checks, SWIFT checks, and rental-fraud checks. The available description does not specify the individual input fields, output schemas, or error responses for these checks.

This makes the server relevant to the 💰 Finance & Fintech category, particularly for applications that need repeatable checks around financial identifiers, tax identifiers, payment messaging identifiers, or rental-fraud signals. The word “deterministic” indicates that the service is intended to produce repeatable results for the same supported inputs, but the supplied material does not define the underlying rules or data sources.

## How it works

The openfang-rail MCP server makes its checks available through MCP. An MCP-compatible client can therefore use the server as a tool endpoint, subject to the server’s payment requirements. The repository or service address provided for the listing is https://rail.akrivis.in.

Each call uses x402 with USDC payment, according to the listing description. Calls also produce signed receipts. The available information does not explain the wallet setup, payment headers, receipt format, signing method, network, token contract, or how clients verify receipts. Developers should confirm those details from the service documentation before integrating it into an automated workflow.

## Tools and capabilities

The listed capabilities are:

- Check IBAN data.
- Check LEI data.
- Check VAT data.
- Check SWIFT data.
- Check for rental fraud.
- Pay for calls in USDC through x402.
- Receive signed receipts for calls.

The material does not provide formal MCP tool names, parameter definitions, response examples, rate limits, supported countries, identifier coverage, or a distinction between validation and lookup operations. Those details are important when designing prompts, schemas, retries, and downstream decision logic.

## Limitations and notes

The service is not described as a general-purpose financial data provider. The supplied description only supports the five named check categories and the per-call payment and receipt model. It does not establish that results are sufficient for regulatory decisions, underwriting, onboarding, sanctions screening, or fraud adjudication.

No README is available for this listing. As a result, setup instructions, required credentials, transport details, supported MCP clients, environment variables, licensing, and operational requirements cannot be confirmed here. The openfang-rail MCP server should be evaluated against the service’s own documentation before deployment, especially where payment authorization, signed-receipt verification, or financial decisions are involved.
