Current situation
When using integration via the Atlassian Rovo Model Context Protocol (MCP) server to perform Jira JQL searches, the expand=changelog parameter is currently ignored. 

Suggested improvement
Update the Atlassian Rovo MCP Server's JQL search tool to support and pass the expand parameter (specifically expand=changelog) 

Workarounds

• The two-step approach: Use the MCP JQL search to find the issue keys you need, then call the dedicated changelog REST API endpoint for each specific issue.

• Use the REST API directly: If you need to pull changelog data in bulk during a search, it's best to bypass the MCP integration and call the Jira REST API directly with expand=changelog.
