frame it refers to. +- Share bounded, read-only capture history with an MCP client through a bundled command-line tool that never opens a network port, scoped to one Project you grant and revoke in

incomplete, keep MCP activity names allowlisted, reject undeclared + MCP arguments, and prevent the synthetic Assistant walkthrough from invoking capture-helper setup. +- Keep Assistant transcript

Packet bytes, payload bodies, URLs, file paths and credentials are never included. + +**Read the answer honestly.** Answers stream as they arrive. **Stop** ends one, and whatever text had +arrived is kept and marked incomplete — Tracexy never presents a partial answer as a conclusion, and +the same label appears when a length or time limit is reached. **Retry** re-sends the last prompt, and +**New conversation** starts over. Changing Project, workspace, session, endpoint or model cancels an +answer in flight rather than letting it land under something it does not describe. + +**Follow the evidence.** Citations such as `frame-1024` appear as buttons under an answer; clicking one +opens that exact frame in the evidence inspector, the same route a Findings row uses. A citation the +model invents is not clickable — it resolves to nothing rather than to the wrong frame. + +Conversations are kept per Project workspace, in memory, for the life of the app session. Prompts and +answers are not written to disk. + +## MCP for external clients + +Tracexy bundles a free, read-only MCP command-line tool so an MCP client — an editor, an agent, a +notebook — can read bounded summaries from **one Project you authorize**. It speaks JSON-RPC over +stdin and stdout and **never opens a network port**. + +Open **Settings → MCP & Assistant**. The pane names the current Project, the field families that will +be disclosed, and the maximum rows one request may read, then **Grant Access** issues the grant. The +pane also shows the bundled command path and a ready-to-paste client configuration; **Copy Client +Configuration** puts it on the clipboard. Point your MCP client at that command — it needs no port, +host or token. + +A client sees exactly three read-only tools: `describe_scope`, `list_captures` and `list_sessions`. +There is no tool for packet bytes, capture files, file paths, raw frames, capture control or writes, +and a process or host filter is refused unless you disclosed that field. + +**Recent activity** lists what clients called: the time, the tool, the outcome, the Project, and the +*names* of the filter fields used — never the values, and never anything read back. + +Switching Projects or pressing **Revoke** invalidates the grant, so the next call from any connected +client fails closed. Re-issuing a grant also supersedes the old one; reconnect the client afterwards. ## Software updates From 08f3599653d7926f34dd6470b3575ae2662f2d23 Mon Sep 17 00:00:00 2001 From: Stephen <9362970+LocNguyenHuu@users.noreply.github.com> Date: Tue, 15 Sep 2026 19:57:07 +0700 Subject: [PATCH 02/23] fix(decoder): bound IP payloads, skip later fragments, decode VLAN tags - Clamp the transport payload to the IPv4 total length / IPv6 payload length so Ethernet padding and trailers are never counted as TCP sequence space (false overlap/retransmission findings, padding leaking into Follow Stream). A zero length (segmentation offload) or one beyond the captured bytes keeps the captured payload. - Stop at the IP layer for non-first IPv4/IPv6 fragments and for an IPv4 header shorter than 20 bytes instead of reading ports out of payload. - Walk 802.1Q / 802.1ad tags (up to two) to the encapsulated EtherType so trunk- and mirror-port captures form sessions. - Mask the classic pcap link-type word to its low 16 bits so libpcap's FCS-length hint does not hide the link type. --- Tracexy/Core/Capture/PcapReader.swift | 12 +- Tracexy/Core/Capture/PcapStreamReader.swift | 3 +- .../Protocol/PacketDecoder+LinkLayer.swift | 36 +++- Tracexy/Core/Protocol/PacketDecoder.swift | 73 +++++++- .../Core/Capture/PcapReaderTests.swift | 20 +++ .../Core/Protocol/IPPayloadBoundsTests.swift | 158 ++++++++++++++++++ .../Protocol/LinuxCookedDecodeTests.swift | 17 +- .../Core/Protocol/VLANDecodeTests.swift | 85 ++++++++++ 8 files changed, 393 insertions(+), 11 deletions(-) create mode 100644 TracexyTests/Core/Protocol/IPPayloadBoundsTests.swift create mode 100644 TracexyTests/Core/Protocol/VLANDecodeTests.swift diff --git a/Tracexy/Core/Capture/PcapReader.swift b/Tracexy/Core/Capture/PcapReader.swift index eaa0741..6bbc8ea 100644 --- a/Tracexy/Core/Capture/PcapReader.swift +++ b/Tracexy/Core/Capture/PcapReader.swift @@ -131,7 +131,8 @@ nonisolated enum PcapReader { throw PacketError.malformed(String(format: "pcap: unknown magic 0x%08X", rawMagic)) } - let linkType = format.littleEndian ? try buffer.u32le(20) : try buffer.u32(20) + let rawLinkType = format.littleEndian ? try buffer.u32le(20) : try buffer.u32(20) + let linkType = MagicFormat.linkType(fromHeaderField: rawLinkType) var frames: [CapturedFrame] = [] var offset = globalHeaderSize @@ -225,6 +226,15 @@ nonisolated struct MagicFormat { let littleEndian: Bool let nanosecond: Bool + /// The `DLT_*` value carried in a classic global header's link-type word.

From 322cee2f8cd553379c781ca9dc277d61e967d6f6 Mon Sep 17 00:00:00 2001 From: Stephen <9362970+LocNguyenHuu@users.noreply.github.com> Date: Tue, 15 Sep 2026 19:57:07 +0700 Subject: [PATCH 03/23] fix(session): record late resets, keep-alives, DNS response timing and orientation - A reset arriving after an orderly close (or after the connection was published) is recorded as a reset observation, so a session shown as an error carries the matching finding and evidence. - A one-byte probe one behind the expected sequence is a keep-alive, not a retransmission. - DNS latency is measured from the header's QR bit, so an answerless response (NXDOMAIN, NODATA) still ends the exchange. - A session captured mid-stream is oriented by the SYN sender, or toward the service port when no SYN was seen, so the remote host rather than this Mac's ephemeral socket reads as the destination. --- Tracexy/Core/Session/ConnectionTable.swift | 14 ++- Tracexy/Core/Session/SessionAccumulator.swift | 66

The direct libpcap path reports the same way. The new batch field is optional, so an older helper stays compatible. - Session export streams the capture file record by record and keeps only the selected session's frames, instead of loading the whole capture into memory. - A replaced helper XPC connection is no longer discarded by the previous connection's late invalidation handler. - The coordinator keeps the app-wide settings store for launch-time preferences. --- Shared/CaptureFrameTransport.swift | 14 +++++- Tracexy/Core/Capture/LiveCapture.swift | 25 +++++++++-- Tracexy/Core/Services/HelperClient.swift | 19 +++++++- Tracexy/Models/Session/SessionExport.swift | 35 +++++++++++++++ ...ontentCoordinator+CapturePersistence.swift | 22 +++++++--- ...MainContentCoordinator+SessionExport.swift | 11 ++--- .../ViewModels/MainContentCoordinator.swift | 35 +++++++++++++++ TracexyCaptureHelper/CaptureService.swift | 23 +++++++++- TracexyCaptureHelper/PcapCapture.swift | 22 ++++++++-- .../Core/Session/SessionExporterTests.swift | 27 ++++++++++++ .../Shared/CaptureFrameTransportTests.swift | 15 +++++++ .../CaptureSourceFailureTests.swift | 44 +++++++++++++++++++ 12 files changed, 266 insertions(+), 26 deletions(-) create mode 100644 TracexyTests/ViewModels/CaptureSourceFailureTests.swift diff --git a/Shared/CaptureFrameTransport.swift b/Shared/CaptureFrameTransport.swift index 38f5115..55a7c71 100644 --- a/Shared/CaptureFrameTransport.swift +++ b/Shared/CaptureFrameTransport.swift @@ -104,11 +104,13 @@ nonisolated final class FrameBatchMessage: NSObject, NSSecureCoding, @unchecked frames: [CapturedFrameMessage], bufferDroppedCount: UInt64, captureLinkType: UInt32, - stats: HelperCaptureStats? + stats: HelperCaptureStats?, + readFailure: String? = nil ) { self.frames = frames self.bufferDroppedCount = bufferDroppedCount self.captureLinkType = captureLinkType + self.readFailure = readFailure statsAvailable = stats != nil statsReceived = stats?.received ?? 0 statsDroppedByKernel = stats?.droppedByKernel ?? 0 @@ -126,6 +128,8 @@ nonisolated final class FrameBatchMessage: NSObject, NSSecureCoding, @unchecked statsReceived = UInt32(bitPattern: coder.decodeInt32(forKey: Key.statsReceived)) statsDroppedByKernel = UInt32(bitPattern: coder.decodeInt32(forKey: Key.statsDroppedByKernel)) statsDroppedByInterface = UInt32(bitPattern: coder.decodeInt32(forKey: Key.statsDroppedByInterface)) + // Absent from replies of a helper older than this key: no failure known. + readFailure = coder.decodeObject(of: NSString.self, forKey: Key.readFailure) as?
