ytt-mcp: YouTube Transcript MCP Server

MCP Server to fetch transcripts for YouTube videos.

Installing and Running

The most convenient way to install and run is to use uv and then invoke the package using uvx

Related MCP server: youtube-mcp

Using MCP Inspector (for development/debugging/testing only)

uv run fastmcp dev ytt_mcp.py

This will generate a localhost URL that can be used to examine and test out the server.

Claude Desktop

Go to Settings → Developer, and then click on Edit Config. This will open the claude-desktop-config.json file in your default editor. Make the following addition

{
  "mcpServers": {
    …<rest of the config>…
    "ytt-mcp": {
      "command": "uvx",
      "args": ["ytt-mcp"]
    }
  }
}

Relaunch Claude config and try out the server as shown in the screenshot below

Raycast

If you are using Raycast, you can install the MCP server by invoking the Install Server command from the MCP extension.

After that you can refer to the MCP server as @youtube-transcript and interact with it. You can also use it in a Raycast AI Command with a prompt. For example, here is a prompt I use to extract and summarize a YouTube URL in the clipboard

@youtube-transcript fetch the Youtube transcript of the video: {clipboard | raw}

Comprehensively summarize the transcript with the following format:
"""
### Key Takeaways

- <EXACTLY three bullet points with the key takeaways, keep the bullet points as short as possible>
"""

### Theme Wise Breakdown
<divide the transcript into thematic sections and summarize each section comprehensively. reuse any existing section delimiters the article already has. If not add your own. keep the content of the breakdown in the same order as it appears in the webpage text.>

Some rules to follow precisely:
- ALWAYS capture the perspective and POV of the author
- NEVER come up with additional information

    Disambiguation5/5

    With only one tool, there is no possibility of ambiguity or overlap between tools, as there are no other tools to compare it to. The tool's purpose is clearly distinct by default.

    Naming Consistency5/5

    Since there is only one tool, naming consistency is inherently perfect; there are no other tools to create inconsistency or mixed conventions. The tool name follows a clear verb_noun pattern.

    Tool Count2/5

    A single tool is too few for most practical server purposes, as it severely limits functionality and scope. This feels thin and incomplete for a YouTube-related server, which might typically include operations like search, list, or metadata retrieval.

    Completeness2/5

    The tool surface is severely incomplete for a YouTube domain; it only provides transcript retrieval with no support for other common operations like video search, channel information, or playlist management. This will cause significant agent failures in broader tasks.
