SysPlant is a python generation tool of the currently known syscall hooking methods. It currently supports following gates (aka: iterators):

  • Hell's Gate : Lookup syscall by first opcodes
  • Halos's Gate : Lookup syscall by first opcodes and search nearby if first instruction is a JMP
  • Tartarus' Gate : Lookup syscall by first opcodes and search nearby if first or third instruction is a JMP
  • [FreshyCall

Questions

What is the SysPlant MCP server?

Your Windows syscall hooking factory - feat Canterlot's Gate - All accessible over MCP

What tools does SysPlant expose?

9 in total: 9 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is SysPlant safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does SysPlant need?

No credential environment variables were found in its source, so it appears to need none.

How does SysPlant run?

It speaks streamable-http, so it runs as a service you connect to over the network. It is published on npm as sysplant-docs at 1.0.0.

How current is this page?

The grade is for one exact copy of the source (08b2d081a6ad), read on 2026-10-07. The repository is watched and re-audited when it changes.
