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.
