`validate_isbn`

Pack: isbn · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/validate_isbn for the schema, then POST the same URL with its arguments for the data.

Validate an ISBN-10 or ISBN-13 (keyless, offline): detects the format and checks the check digit (ISBN-10 uses mod-11 with an “X” for 10). Hyphens/spaces ignored. Validates the number, not the book.

Parameters

Name	Type	Required	Description
`isbn`	string	yes	An ISBN-10 or ISBN-13, e.g. “978-0-306-40615-7”.
