What APIShed MCP server does

The APIShed MCP server exposes a collection of validation and utility operations for AI clients using MCP. Its listed validation coverage includes Polish identifiers such as PESEL, NIP, and REGON; financial and banking identifiers such as IBAN and SWIFT-BIC; product and document codes such as EAN and ISBN; the Luhn algorithm; and VAT-related checks.

The service also covers operations beyond identifier validation. Its advertised capabilities include reverse Polish notation (RPN) calculation, date math, hashing, and tokens. The available description does not specify individual operation names, argument formats, result schemas, or whether all operations are exposed as separate MCP tools.

Tools and capabilities

Based on the published description, the APIShed MCP server is relevant to agents that need to:

• Validate PESEL values.
• Check NIP and REGON identifiers.
• Validate IBAN and SWIFT-BIC values.
• Check values using Luhn rules.
• Validate ISBN and EAN codes.
• Perform VAT-related validation.
• Evaluate expressions using reverse Polish notation.
• Carry out date calculations.
• Apply hashing operations.
• Work with tokens.

These capabilities group into two practical use cases: checking structured identifiers and delegating small, general-purpose utility operations. The description does not provide language-specific SDK requirements or indicate that the server is limited to a particular programming ecosystem.

Limitations and notes

The available source material is limited to the product name, a short capability description, and the APIShed website address. It does not document installation commands, transport mode, authentication, environment variables, configuration fields, MCP tool names, input and output formats, error behavior, rate limits, or supported client applications.

The APIShed MCP server should therefore be evaluated against the exact validation rules and response formats required by an application before adoption. The listing confirms that the named identifier families and utility categories are supported, but it does not define how edge cases are handled. In particular, the description does not explain whether VAT checks are country-specific, which hash or token formats are available, or what date and RPN expression syntax the service accepts.

No license information is provided in the supplied material. Setup guidance and client compatibility should be confirmed from the project documentation before deployment.
