MCPTrace

A Volatility 3 plugin for extracting MCP/JSON-RPC message candidates from Windows x64 and Linux x86-64 memory dumps. Preserves message content, process IDs, virtual addresses, and SHA-256 hashes, with optional JSONL export.

Installation

Requires Python 3.10+. Run in an activated virtual environment:

git clone https://github.com/Kowntaewook/MCPTrace.git
cd MCPTrace
python -m pip install .

Usage

Run from the repository root. Choose the plugin matching the dump's OS and replace the example paths and PIDs.

Windows

vol -f windows.raw windows.pslist.PsList
mkdir output-windows
vol -p plugins -f windows.raw -o output-windows windows.mcptrace.MCPTrace --pid 4242 --dump

Linux

Place ISF symbols matching the dump's kernel build in symbols/linux/ first.

vol -s symbols -f linux.lime linux.pslist.PsList
mkdir output-linux
vol -p plugins -s symbols -f linux.lime -o output-linux linux.mcptrace.MCPTrace --pid 4242 --dump

• Omit --pid to scan all processes, or pass multiple PIDs: --pid 4242 5252.
• --dump exports per-process JSONL files to the directory specified by -o.
• Use vol -p plugins windows.mcptrace.MCPTrace -h (or the Linux equivalent) for all options.
