About Ue Trace
Ue Trace is an MCP server in the Gaming category: mCP server for LLM-driven Unreal Engine .utrace profiling. Wraps the headless TraceDigest UE Program and manages a long-lived daemon per trace.
Install
claude mcp add ue-trace -- npx -y @mtuska/ue-trace-mcpnpx -y @mtuska/ue-trace-mcpThis server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.
Tools (6)
trace_channelsEnumerate channels present in the capture with their enabled/read-only flags. Call this first so the LLM knows which other tools have data.
Parameters not published.
trace_frameDrill into one frame: every CPU event that ran during it. Already cross-channel by intent.
Parameters not published.
trace_overviewFirst-look snapshot. Top-level keys: `channels[]`, `cpu`, `memory`, `memalloc`. The `cpu` sub-block keeps the v0.3 shape verbatim (`frame_count`, `frame_stats`, `slowest_frames`, `events`) — only the path prefix changed.
Parameters not published.
trace_queryIntent-dispatched escape hatch. Pick an intent + params for cross-cutting questions the specific tools can't answer (see below).
Parameters not published.
trace_statusPer-daemon PID/RSS/uptime + system memory + `loading[]` for in-flight spawns.
Parameters not published.
trace_unloadEvict the daemon for one trace. Frees memory immediately.
Parameters not published.
