Burn styled, word-timed karaoke captions into any video - captions API and MCP server for agents.

VerifiedStreamable HTTPWeb executableMedia & Design

Overview

AI-generated overview

A remote MCP server that lets an assistant burn styled, word-timed karaoke captions into videos through the caption.sh captions API.

What you can do
Connect an assistant to the caption.sh captions service so it can add captions to video files. Captions are styled and timed word by word in a karaoke style. The manifest lists no individual tools, so the exact operations are not documented here.
When to use it
Useful when you want an agent to produce captioned or karaoke-style word-timed videos without wiring up the captions API yourself.
Requirements
A remote endpoint at mcp.caption.sh reached over streamable HTTP. OAuth authentication is required. No environment variables or headers are declared.
Before you install
OAuth grants the server access to your caption.sh account, and video processing may consume account quota or credits; check the provider's terms before use. Captions are written into video output, so review results before publishing.

Installation

In SourceWeft

  1. Open caption.sh 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/sh.caption%2Fmcp/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.
