The request names GitHub, so GitHub comes first; its indexed action github_create_pull_request_review_comment and createCommentOnAIssue write comments rather than load them. For loading existing PR comments, the closest matches are Smithery's get_pull_request_comments [2 and 11 not applicable], Crunchtools' list_pull_request_comments_tool [3, 13], and MewCP's pull_request_read with get_comments [4, 14].
