Overview

AI-generated overview

Burns caption files into a video, returning a captioned MP4 from an uploaded video plus SRT or VTT subtitles.

What you can do
CaptionPipe is a hosted MCP server that takes a video file together with subtitle files and returns a video with the captions burned into the picture. It accepts MP4 video and SRT or VTT subtitle input, and the output is a captioned MP4. The service is prepaid rather than subscription-based, and it is reached as a remote endpoint rather than run locally.
When to use it
Use it when an assistant needs to produce a hard-coded, always-visible caption track on a video, for example for social clips, presentations, or platforms that do not render separate subtitle files. It is not needed if soft subtitles or a standalone SRT or VTT file are enough.
Requirements
A remote MCP connection to the provider's hosted endpoint over streamable HTTP, with OAuth sign-in required. No local runtime, package, environment variable, or header is declared. A prepaid account with the provider is implied by the prepaid, no-subscription model.
Before you install
Video and subtitle files are uploaded to a third-party hosted service, so consider whether the content is sensitive. The service is prepaid, so usage consumes paid credit. OAuth grants the server access under your account; review the scopes before authorizing.

Installation

In SourceWeft

  1. Open CaptionPipe 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/com.captionpipe%2Fcaptionpipe/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.
