Claude Code thumbnails image_watermark

How to: Claude Code thumbnails image_watermark

client:Claude Code transport:streamable-http tool:image_watermark

Add thumbnails to Claude Code

  1. 01

    Run this in your project directory.

claude mcp add --transport http thumbnails https://mcp.zovo.one/mcp/thumbnails
  1. 02

    Restart your session so the server is picked up.

  2. 03

    Ask for something image_watermark does. Claude Code lists the server's tools on connect and calls image_watermark itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that thumbnails's identifier in your config matches the one above exactly.

Adds it for this project only. Append --scope user to make it available everywhere. Claude Code docs

Set these first

thumbnails will not start until these are set, so image_watermark never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
