latch-agent 0.1.3

Universal gating and audit layer for AI agents — policy-based tool gating with WebAuthn approval flows

latch-agent

Universal gating and audit layer for AI agents. Intercepts tool calls, evaluates them against YAML policies, logs decisions, and supports WebAuthn approval flows.

Quick Start

pip install latch-agent
latch init

OpenClaw Integration

openclaw plugins install openclaw-latch

The plugin automatically installs latch-agent, runs latch init, and registers latch-serve as an MCP server.

Claude Code Integration

Add latch as a hook in your Claude Code settings:

{
  "hooks": {
    "PreToolUse": [{ "command": "latch-hook" }]
  }
}

Codex Integration

Set up latch as a pre-tool-use hook in your Codex configuration, pointing to latch-hook.

Policy Format

  - match: { tool: Bash }
    action: ask
  - match: { tool: 'Edit|Write|NotebookEdit' }
    action: ask
  - match: { tool: 'Read|Glob|Grep' }
    action: allow

Actions: allow, deny, ask, browser (browser-based approval), webauthn (passkey required).
