The video clipping MCP server

Connect Katto to ChatGPT, Claude, Cursor or any MCP-compatible AI agent and clip, caption, reframe, and dub videos through natural conversation. Connect in one click with the hosted OAuth endpoint — sign in with your Katto account, no API key stored on disk — or run it locally with a single npx command.

Two ways to connect

Hosted connector

Best for Claude web/desktop and any OAuth 2.1 client (the endpoint uses OAuth 2.1 + Dynamic Client Registration). Add the server URL and sign in with your Katto account — the key never touches your disk, and you can revoke access anytime.

Server URL:  https://mcp.katto.tech/mcp
Transport:   Streamable HTTP
Auth:        OAuth (sign in with Katto)

Local (npx)

Best for Cursor, CI and scripts. Add Katto to your MCP client config with an API key from your dashboard. The hosted endpoint above also accepts a key directly via Authorization: Bearer sk_live_….

{
  "mcpServers": {
    "katto": {
      "command": "npx",
      "args": ["-y", "katto-mcp"],
      "env": { "KATTO_API_KEY": "sk_live_..." }
    }
  }
}

Then just ask your agent: “Clip the best moments from this podcast and reframe them for TikTok.”
