Katto turns a long video into short vertical clips: it finds the moments worth posting, cuts them to 9:16, reframes around whoever is on screen, burns in captions and gives every clip a score from 0 to 100 with the reason. You can do all of that from the Katto dashboard, but you can also do it from the AI assistant you already have open.

This guide shows how to connect Katto to Claude, ChatGPT, Claude Code, Gemini CLI and Cursor, what you can ask once it's connected, and what to expect.

Katto is also submitted to Anthropic's Connectors Directory. Until the listing is approved, the custom connector above is the way in, and it gives you the same tools.

Katto is submitted to the ChatGPT plugin directory as well, and is in review there.

claude mcp add --transport http katto https://mcp.katto.tech/mcp Enter fullscreen mode Exit fullscreen mode Then run /mcp in Claude Code and sign in when it asks.

gemini extensions install https://github.com/miracleweasel/katto-mcp Enter fullscreen mode Exit fullscreen mode Then /mcp auth katto to sign in. If you moved to Antigravity CLI, the setup page at katto.tech/mcp/gemini shows the equivalent configuration.

Add the hosted server to your client's MCP configuration (for Cursor, ~/.cursor/mcp.json or.cursor/mcp.json in a project):

{ "mcpServers": { "katto": { "url": "https://mcp.katto.tech/mcp" } } } Enter fullscreen mode Exit fullscreen mode Prefer a local server? npx -y katto-mcp with an API key from your Katto dashboard does the same job.

Once Katto is connected, talk to it the way you would to a colleague. A few prompts that work well:

There are 29 tools in total, from creating a job or uploading a local file to retitling a clip, adding a hook, translating captions and publishing to 7 platforms. The full list, with what each tool does and what it costs in quota, is at katto.tech/mcp/tools.

Katto is billed per source video, not per minute or credit: a 90-minute podcast uses the same allowance as a 10-minute clip, within your plan's length limit. Free: 2 videos a month up to 30 minutes. Solo: 10 videos up to 60 minutes. Creator: 25 videos up to 90 minutes, with AI dubbing in 19 languages and scheduling. Assistant access is included on every plan.
