Return reactions on pull request reviews and review comments in pull_request_read #3780
Description
We'd like to read reactions on pull request reviews and review comments through the MCP server.
Today
issue_read(get_comments) already includes areactionssummary.pull_request_readdoes not:get_reviewsreturns no reactions.get_review_commentsreturns no reactions on each comment.
- GraphQL exposes these via
reactionGroupsonPullRequestReviewandPullRequestReviewComment.
Ask
Include a reaction summary (counts per reaction type, like the existing reactions field on issue comments) on:
- each review returned by
get_reviews - each comment returned by
get_review_comments
Opt-in behind a parameter is fine if response size is a concern.

I'd like to work on this. I have a local implementation that adds an optional
include_reactionsflag forget_reviewsandget_review_comments, using the same aggregate reaction fields as issue comments.Review counts are fetched for the current page after lockdown filtering. Comment counts use the existing GraphQL thread query. The normal test suite and lint pass locally, including MCP client-session tests for both methods, empty results, and zero counts. I am finishing the full race check before opening the PR.
