Overview

AI-generated overview

A remote MCP server that lets an assistant create, check and edit YouTube thumbnails from a chat brief, with the price shown before generation.

What you can do
Turn a short brief into a YouTube thumbnail from the chat, with the price shown before generation begins. Check thumbnails against the brief and refine or edit them afterwards. The manifest lists no individual tools, so the exact commands are not documented here.
When to use it
Useful when you want an assistant to draft and iterate on YouTube thumbnails without leaving the chat, and you want to see the cost before any image is generated.
Requirements
A remote endpoint at the provider's site, reached over streamable HTTP. OAuth sign-in is required. No environment variables or headers are declared.
Before you install
Generation appears to be a paid service, so expect charges; confirm the price shown before generating. Thumbnail briefs and any uploaded material are sent to the provider. OAuth grants the server access to your account, so review the scopes requested.

Installation

In SourceWeft

  1. Open ThumbnailMaker in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/so.thumbnailmaker%2Fthumbnailmaker/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
