Inside Drafter for Claude only

Drafter for Claude is a separate program, one file, with these inside it. They are not in the app or the website. The file ends with the full licence of every package it carries, these two and the small JSON Schema helpers the SDK carries in its own files (Ajv, ajv-formats, content-type, fast-deep-equal, fast-uri, and json-schema-traverse, under the MIT and BSD-3-Clause licences).

@modelcontextprotocol/server

Terms: use, copy, change, and share it freely, keeping its copyright, licence, and notices with it, and saying what was changed in a changed copy. Some of its earlier code is still under the MIT License, as its licence explains. @modelcontextprotocol/server’s licence (full text)
