How to Attach Line-Specific Review Comments to Pull Requests

This guide explains how to add line-specific review comments to pull requests using the GitHub CLI (

gh

) API or

mcp__github_inline_comment__create_inline_comment

if it not available, similar to how the GitHub UI allows commenting on specific lines of code.

Preferred Approach: Using MCP GitHub Tools

If available

, use the

mcp__github_inline_comment__create_inline_comment

MCP tool for posting line-specific inline comments on pull requests. This approach provides better integration with GitHub's UI and is the recommended method.

Fallback

If the MCP tool is not available, use the GitHub CLI ( gh ) API methods described below: For single comments: Use the /comments endpoint (see Adding a Single Line-Specific Comment ) For multiple comments: Use the /reviews endpoint (see Adding Multiple Line-Specific Comments Together ) Overview While gh pr review provides basic review functionality (approve, request changes, general comments), it does not support line-specific comments directly . To add comments on specific lines of code, you must use the lower-level gh api command to call GitHub's REST API directly. Prerequisites Show more
