Checksum Validator is a Model Context Protocol (MCP) server: Validates Luhn, IBAN, ISBN, EAN/UPC, SWIFT/BIC, and EU VAT checksums and formats. In practice that means any MCP-compatible AI assistant can call Checksum Validator's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://apished.com/mcp/v1/checksum and you're connected, with nothing to install locally. The current release is v1.0.0.
Checksum Validator is listed under Development on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
