How to Set Up and Use Sysplant
Sysplant is a Windows syscall hooking factory that generates low-level syscall stubs for security research, implementing multiple retrieval techniques including the novel Canterlot's Gate method. It supports NIM, C, C++, and Rust output languages and can be driven via MCP for AI-assisted shellcode and evasion research workflows. Security researchers use it to study EDR bypass techniques, test detection logic, and prototype offensive tooling in a controlled environment.
Prerequisites
- Python 3.8+ installed
- pip package manager available
- Windows environment (for using generated syscall stubs) or Linux/macOS for code generation
- An MCP-compatible client (Claude Desktop or similar)
- Security research context — this tool is intended for authorized penetration testing and research only
Install sysplant via pip
Install the sysplant package from PyPI. This provides both the CLI tool and the MCP bridge script.
pip install sysplantList available syscall presets and iterators
Verify installation and explore available syscall retrieval methods and preset function groups.
sysplant listStart the MCP server bridge
Launch the MCP bridge to expose sysplant functionality over stdio for Claude Desktop or another MCP client. Use --transport sse and --port for web-based clients.
python bridge_mcp_sysplant.py
# Or for SSE/web clients:
python bridge_mcp_sysplant.py --transport sse --port 9090Configure Claude Desktop
Add sysplant to your claude_desktop_config.json. Point the command to Python and the bridge script path after cloning the repository.
{
"mcpServers": {
"sysplant": {
"command": "python",
"args": ["/path/to/sysplant/bridge_mcp_sysplant.py"]
}
}
}Generate a syscall stub manually to verify
Test sysplant's code generation directly from the CLI before relying on the MCP interface. This generates C code using Canterlot's Gate for the common syscall preset.
sysplant generate -c -o syscalls.c canterlotUse Claude to drive code generation
Once the MCP server is running and configured, ask Claude to generate syscall stubs with specific parameters for your research.
Sysplant Examples
Client configuration
Claude Desktop configuration running the sysplant MCP bridge via Python. Clone the repository first to get the bridge script.

"mcpServers": {
"sysplant": {
"command": "python",
"args": ["/path/to/sysplant/bridge_mcp_sysplant.py"]
}
}
}Prompts to try
Security research prompts for working with Windows syscall generation via sysplant.
- "Generate NIM code using Canterlot's Gate for the NtAllocateVirtualMemory and NtWriteVirtualMemory syscalls with name scrambling enabled."
- "List all available syscall retrieval methods and explain the difference between Hell's Gate and Canterlot's Gate."
- "Generate C++ code using the indirect stub method for the common syscall preset and output it to evasion.cpp."Troubleshooting Sysplant
bridge_mcp_sysplant.py not found after pip install
The bridge script is part of the source repository, not the PyPI package. Clone the repo with 'git clone https://github.com/x42en/sysplant' and run the bridge from the cloned directory.
Generated NIM code fails to compile on Windows
Ensure you have the Nim compiler installed and that you are targeting the correct architecture. Use '-x64' for 64-bit targets (default) or '-x86' for 32-bit. Verify the syscall numbers match your target Windows version.
MCP server connection fails with SSE transport
When using '--transport sse', ensure the port (default 9090) is not blocked by a firewall. Configure your MCP client to connect to 'http://localhost:9090' with the SSE transport type.
