# Hookdeck CLI v3

Published 25 September 2026 · Platform

Event Gateway write mode and Outpost commands

Hookdeck CLI v3 adds write mode to the Event Gateway MCP server. Pass `--allow-write` when you start `hookdeck gateway mcp` and the agent can create, update, retry, and dismiss. Without the flag the server stays read-only. Pause and unpause stay available either way.

`hookdeck outpost` manages tenants, destinations, and deliveries on a managed Outpost project. `hookdeck outpost mcp` exposes the same commands to an agent, with the same `--allow-write` flag.

```bash
npm install -g hookdeck-cli@latest

```
