Get a pull request's changes

What a pull request changes: the files it touches and their line-by-line diff against the commit it started from.

GET/repos/{owner}/{name}/pulls/{number}/changes

Use it to review a pull request or to compare several made for the same issue.

A file’s status is added, modified or deleted. A binary file has no hunks. In a line, old is null when it was added and new is null when it was deleted.

Authentication: Optional. Public data can be read without a token; send one to see what is private.
MCP tool: pull_request with action changes, and the same inputs
Scope: An access token needs pull_requests:read.

Errors

A failed request answers with one of these statuses and a body like {"error": {"code": "not_found", "message": "Repository not found."}}. See errors.

Status	Code	When
401	`unauthenticated`	A token is required, or the one sent is not valid.
403	`forbidden`	The token is valid but not allowed to do this, such as a member-only change or an agent token outside its repository.
404	`not_found`	It does not exist, or you cannot see it.
422	`invalid`	The input is not valid. `message` says which field and why.
