katto-mcp

MCP server for Katto — turn long videos into scored, captioned 9:16 clips from any MCP client (Claude Desktop, Cursor, Claude Code, ChatGPT, …).

Two ways to connect:

Hosted (zero-install, recommended)

Point any OAuth-capable MCP client (ChatGPT, Claude web/desktop, MCP Inspector) at the hosted endpoint and sign in with your Katto account — the key never touches your disk, and you can revoke access anytime:

https://mcp.katto.tech/mcp   (Streamable HTTP · OAuth)

Local (npx)

For Cursor, CI and scripts. Create an API key at katto.tech/dashboard/api-keys, then add the server to your MCP client config:

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

The hosted endpoint above also accepts Authorization: Bearer sk_live_... directly for key-based clients.

Tools

• katto_create_clip_job(url, config?) — submit a long video (YouTube, Twitch, Vimeo, Rumble, Zoom, Dailymotion). Returns a job id.
• katto_get_job(id) — poll until status is completed; clips holds the finished MP4 + caption (SRT) urls.
• katto_list_jobs(limit?, cursor?, status?) — list your recent jobs, newest first (keyset pagination via cursor).
• katto_get_clips(id) — just the finished clips of a job.
• katto_get_transcript(id) — the job's timestamped transcript segments ([{ start, end, text }]).
• katto_get_usage() — your plan and remaining monthly video quota.
• katto_cancel_job(id) — cancel a running job and refund the monthly video slot.
• katto_get_account() — the connected account, this key's scopes, and quota.

Jobs draw from your Katto plan's monthly video quota (25 on Creator, 2 on Free). Videos up to 90 minutes. The underlying REST API also supports Idempotency-Key safe retries and read-only scoped keys — see the docs.
