Zn Gate Overview

zn-gate runs locally between coding agents and the tools or content they access. It checks prompts, tool calls, and returned content for prompt injection, while redacting or blocking exposed secrets and protecting credential files. It supports Claude Code, Codex CLI, Cursor, OpenCode, and MCP clients through hooks, a Claude Code plugin, or an MCP-only mode. Reach for it when an agent needs access to local files, MCP servers, or development secrets without exposing those values to its model.

Primary Use Cases for Zn Gate:
  • Protect Claude Code sessions from secret exposure
  • Check MCP and tool content for prompt injection
  • Move .env values into a local encrypted vault
  • Add redaction and policy checks to LangChain tools
