MCP server for the ZPL stability engine — AIN bias detection & neutrality scoring for finance, gaming, AI/ML, security, crypto. 69 tools across 11 categories. Plug into Claude Desktop / Cursor / Windsurf in 10 seconds via `npx. Exposed over MCP by the zpl engine mcp mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.
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:
Everything the assistant can do here goes through one of these:

The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
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. Zpl Engine MCP'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.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
