Codex video download tool

Install Fastdown from a Codex session.

Fastdown is designed for agent-first setup: paste the install prompt into Codex, authenticate once, then let Codex call MCP tools for public short-video links.

Agent: install Fastdown in this environment and connect its MCP tools.
You can run this from Codex, Claude Code, Open Code, or another terminal-based coding agent.

curl -fsSL https://fastdown.pro/cli | sh -s -- --agent auto

What Codex gets after setup

The installer wires a local CLI and MCP server so the video parsing workflow lives inside the same agent session.

Local file output

Codex can save returned media to a local directory when the user asks for a download.

parse_video

Structured inspection

Codex can return platform, title, author, media URLs, warnings and quota without saving files.

Codex can check the signed-in account's daily parse quota before a batch workflow.
