mem-forensics-mcp

Unified Memory Forensics MCP Server - Multi-tier engine combining Rust speed with Vol3 coverage.


Architecture

Three-tier engine automatically routes each tool to the fastest backend:

LLM <-> [mem-forensics-mcp (Python)] <-> memoxide (Rust child, stdio MCP)
                                     <-> Volatility3 (Python library)
Tier Engine Speed Coverage
Tier 1 Rust (memoxide) Fast pslist, psscan, cmdline, dlllist, malfind, netscan, cmdscan, search, readraw, rsds
Tier 2 Python analyzers Medium Process anomalies, C2 detection, credentials, YARA, VT integration
Tier 3 Volatility3 Slower Any vol3 plugin (filescan, handles, svcscan, driverscan, ...)

Installation

Prerequisites

# Install uv (fast Python package manager)
curl -LsSf https://astral.sh/uv/install.sh | sh

# Ensure Python 3.10+
python3 --version

Install from PyPI

uv venv .venv
uv pip install --python .venv/bin/python3 mem-forensics-mcp

Install from source

git clone https://github.com/x746b/mem_forensics-mcp.git
cd mem_forensics-mcp

# Full install (recommended)
uv sync --extra full

# Minimal (Vol3 only, no YARA/VT)
uv sync --extra volatility3

Build Rust Engine (optional)

Prebuilt binaries ship for aarch64-linux and x86_64-linux in engines/memoxide/. The server auto-detects the host architecture. To build from source:

# Requires Rust toolchain (https://rustup.rs)
cd engines/memoxide-src
cargo build --release

# Binary lands at engines/memoxide-src/target/release/memoxide
# The server auto-detects it (prefers local build over prebuilt)

Configure Volatility3 (optional)

If Vol3 is installed at /opt/volatility3 it's auto-detected. Otherwise: export VOLATILITY3_PATH="/path/to/volatility3"

Verify

uv run python -m mem_forensics_mcp.server
# Should show: Rust engine: available, Volatility3: available

Add to an MCP client

Register mem-forensics-mcp as a local stdio server in your MCP client's settings. Configuration format and location depend on the client. For clients that accept mcpServers JSON, use:

{
  "mcpServers": {
    "mem-forensics-mcp": {
      "command": "/absolute/path/to/.venv/bin/python3",
      "args": ["-m", "mem_forensics_mcp.server"]
    }
  }
}

Replace the command with the absolute path to the virtual environment's Python interpreter. For a source checkout, this is /path/to/mem_forensics-mcp/.venv/bin/python3 after uv sync. For a PyPI install, use the .venv created during installation. If your client uses a different configuration format, enter the same command and arguments through its MCP server settings.

If Volatility3 is installed in a custom location, set VOLATILITY3_PATH to its absolute path in the server's environment settings (for example, "env": {"VOLATILITY3_PATH": "/path/to/volatility3"} in the JSON example). Use the client's MCP server list to confirm it connects.


Quick Start

# 1. Initialize
memory_analyze_image(image_path="/evidence/memory.raw")

# 2. Full triage
memory_full_triage(image_path="/evidence/memory.raw")

# 3. Drill down
memory_run_plugin(image_path="/evidence/memory.raw", plugin="malfind", pid=1234)

memory_analyze_image reports readiness at two levels:

  • ready and session_ready: an engine opened the image and the session can be reused.
  • raw_ready: OS-agnostic Rust operations such as search and readraw are available.
  • structured_ready: symbols/profile data is sufficient for structure-aware plugins.

ready remains a compatibility alias for session_ready; it does not imply that Volatility process, network, or command plugins can run. Check os_type, structured_ready, capabilities, and warnings before choosing those tools.

For Linux structure-aware analysis, provide either a symbol directory or an explicit ISF file. Linux ISFs are never downloaded or generated automatically:

memory_analyze_image(
    image_path="/evidence/memory.lime",
    symbols_root="/evidence/symbols",
    # or: isf_path="/evidence/symbols/5.10.0-35-amd64.json.xz",
)

Without a matching ISF, LiME images still expose raw search and readraw. The analysis response includes the exact kernel banner and a suggested ISF filename. With symbols loaded, process tree routes to linux.pslist.PsList, command history routes to linux.bash.Bash, and generic Linux Volatility plugins are available through memory_run_plugin.

Example: Full Triage Output

Running memory_full_triage on a Windows 10 memory dump (Win10 19041, x64, VMware):

{
  "threat_level": "critical",
  "risk_score": 100,
  "summary": "Processes: 115 found. Process Anomalies: 4 info-level. Network: 4 flagged of 79 connections. Commands: 56 memory fragments. Injected Code: 12 RWX regions. Correlations: 2 critical.",
  "engine": "rust+python"
}

Key findings:

Category Detail
Suspicious process mmc.exe launched from explorer.exe, loading a .msc file from browser downloads
Injected code 4 RWX private memory regions in mmc.exe, 2 in EXCEL.EXE
Child process dllhost.exe spawned by mmc.exe with executable RWX region
Network svchost.exe connections to external IPs on ports 443/80
Correlations active_implant + active_c2_session flagged as critical
IOCs Suspicious external IPs extracted automatically

Drill-down with filtered filescan:

memory_run_plugin(image_path="memory.raw", plugin="filescan", filter="notepad")
# Returns: 2 of 7612 results matched (server-side grep before truncation)
