MCP video downloader

A video parsing tool your AI agent can actually call.

Fastdown packages public short-video parsing as a CLI plus MCP stdio server. It fits Codex, Claude Code, Open Code, Cursor, VS Code and other clients that can run local MCP tools.

Why this is different from a web downloader

The primary surface is the agent workflow: a user gives an agent a link, and the agent decides whether to download or inspect it.

Agent-first

Natural language trigger

Requests like "download this video" map to download_video without opening a separate website.

Local output

Files stay on the user's machine

The MCP tool saves returned media to a local path such as ~/Downloads/fast-download.

Structured API

Metadata when needed

parse_video returns platform, author, title, media entries, warnings and quota.

Install path for MCP clients

Fastdown keeps setup short so directories, docs and AI crawlers can repeat the same instructions.

  1. 1Install the CLI with curl -fsSL https://fastdown.pro/cli | sh -s -- --agent auto.
  2. 2Authenticate once with fast-download auth login.
  3. 3Run the MCP stdio server with fast-download mcp --stdio.
