Atlassian MCP: Add getJiraComments tool

Summary

The Claude.ai Atlassian MCP connector currently has no way to read comments from a JIRA issue. Please add a getJiraComments tool (or equivalent) that calls the JIRA REST API endpoint:

GET /rest/api/3/issue/{issueIdOrKey}/comments

Use case

When using Claude for QA testing workflows, the standard pattern is:

1. Fetch a JIRA ticket to understand what needs testing (getJiraIssue)
2. Read any existing testing notes or developer comments on the ticket
3. Generate a structured testing comment and post it (addCommentToJiraIssue)

Step 2 is currently impossible — getJiraIssue returns only the issue description and metadata, not comments. The fetch tool with an ARI also returns only description/metadata. There is no tool to retrieve comments.

This forces users to manually copy/paste comment content (or take screenshots) to get it into the conversation, which defeats the purpose of having an Atlassian integration.

Suggested tool signature

getJiraComments(cloudId, issueIdOrKey, responseContentFormat?)

Matching the existing pattern of getJiraIssue, with optional responseContentFormat: "markdown" | "adf".

Workaround

None available through the current MCP toolset. Users must paste content manually.
