Search via MCP server yields no results

[jude]

JQL query produced in Claude Desktop works in Jira's UI, but fails via MCP server.

Details:

• A specific JQL query returns correct and returns results in the Jira web UI

• The same query was tested using Claude Desktop on Sonnet 4, which doesn't return any results

• The JQL syntax is confirmed to be valid and functional outside of MCP.

Expected Behavior:
MCP API should return the same results as the Jira UI, when using identical JQL.

Actual Behavior:
MCP API returns no results for a JQL query that works elsewhere.

Hi @jude ,

Won't be much of a help here, but I'd just like to point out the new MCP forum group where folks are a bit more active when it comes to this specific topic: Atlassian Rovo MCP Server 
That's a discussion group, so you don't have 'questions' types, but you can start a discussion (in the form of a question) so people can chime in.

Cheers,
Tobi
