AIN stability & bias engine — neutrality index for finance, gaming, AI, crypto (63 tools).
If you already use Engine, the engine mcp server is the piece that lets your assistant work with it directly. AIN stability & bias engine — neutrality index for finance, gaming, AI, crypto (63 tools).
Model Context Protocol (MCP) server for the Zero Point Logic Engine — a post-binary stability and neutrality analysis system.
The ZPL Engine computes the AIN (AI Neutrality Index) — a mathematical measure of how stable or biased a system is. It works across:
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Engine's toolset — Format, Category, Core and 11 more — is a fair guide to whether it matches your workflow. It is maintained by cicicalex; worth a glance at recent repository activity before you build anything load-bearing on it.
