How to: Claude.ai thumbnails image_delete_upload

client:Claude.ai transport:streamable-http tool:image_delete_upload

Add thumbnails to Claude.ai

  1. 01

    Open Settings → Connectors → Add custom connector and merge this in. Keep any servers already there.

https://mcp.zovo.one/mcp/thumbnails
  1. 02

    Save the file and restart Claude.ai.

  2. 03

    Ask for something image_delete_upload does. Claude.ai lists the server's tools on connect and calls image_delete_upload 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.

Claude on the web takes a remote URL and completes OAuth in the browser. For a packaged server use Claude Desktop or Claude Code instead. Claude.ai docs

Set these first

thumbnails will not start until these are set, so image_delete_upload 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.
