About zn-gate
zn-gate is an MCP server published by the GitHub account usezn. The local security layer for coding agents: secret redaction, injection checks and an MCP proxy.
It runs on your own machine: your AI client starts it from the npm package zn-gate at version 1.13.1.
It asks for one secret: ZN_API_KEY. Give it a key with the least access that still works.
Version 1.13.1 was published on 20 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 6 pass, 1 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
ZN_LOCAL_ONLY | No | No | Set to true to force local-only mode, even if ZN_CLOUD=1. |
ZN_CLOUD | No | No | Set to 1 to let prompt analysis also query the optional cloud classifier. Off by default. |
ZN_API_KEY | No | Yes | API key for the optional cloud check. Has no effect without ZN_CLOUD=1. |
