Noticed while doing live QA of the tray glance section (#930), but this is a core-side classification issue and predates that PR.
What happens
When an upstream MCP server returns a result with
isError: true— a bad timezone, an unknown tool name, a server-side validation failure — the activity record is stored withstatus=success. Only mcpproxy's own pre-dispatch argument validation producesstatus=error.Why it matters
Every consumer of activity status under-reports failures:
Reproduced during QA: calls to
time:get_current_timewith an invalid timezone and to a nonexistent tool both landed asstatus=success, while an argument-shape violation caught before dispatch landed asstatus=error.Suggested fix
Inspect the MCP result's
isErrorflag when recording the activity entry and classify accordingly. Worth deciding explicitly whether an upstream-reported error should be a distinct status from a proxy-side error — they are different things to debug, and the UI could usefully tell them apart.
