This server provides direct access to video captions and subtitles through a simple interface. <a href="https://glama.ai/mcp/servers/z429kk3te7"><img width="380" height="200" src="https://glama.ai/mcp/servers/z429kk3te7/badge" alt="mcp-server-youtube-transcript MCP server" /></a> ### Installing via Smithery To install YouTube Transcript Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@kimtaeyoon83/mcp-server-youtube-transcript): ```bash npx -y @smithery/cli install @kimtaeyoon83/mcp-server-youtube-transcript --client claude ``` ## Components ### Tools - **get_transcript** - Extract transcripts from YouTube videos - Inputs: - `url` (string, required): YouTube video URL, Shorts URL, or video ID - `lang` (string, optional, default: "en"): Language code for transcript (e.g., 'ko', 'en'). Automatically falls back to available languages if requested language is not found. - `include_timestamps` (boolean, optional, default: false): Include timestamps in output (e.g., '[0:05] text') - `strip_ads` (boolean, optional, default: true): Filter out sponsorships, ads, and promotional content from transcript based on chapter markers - **analyze_video** (optional, requires a TwelveLabs API key) - Analyze a video with [TwelveLabs](https://twelvelabs.io) Pegasus, a video-understanding model. Unlike `get_transcript`, this reasons over what is *shown* on screen, so it produces useful summaries and answers even for videos with little or no speech (demos, gameplay, b-roll, music videos). - Inputs: - `url` (string, required): A publicly reachable **direct video URL** (e.g. an `.mp4`/`.mov`/`.webm` link or a pre-signed URL). TwelveLabs fetches the file server-side, so a YouTube watch page URL will not work — it serves HTML, not a raw video stream. - `prompt` (string, optional): Instruction or question for the model (e.g. `"Summarize this video in 3 sentences"` or `"What products are shown?"`). Defaults to a general summary. - `model` (string, optional, default: `"pegasus1.2"`): Pegasus model to use (`"pegasus1.2"` or `"pegasus1.5"`). - `max_tokens` (number, optional, default: 2048): Maximum response length in tokens. - Requires the `TWELVELABS_API_KEY` environment variable. The transcript tool works without it; analysis is fully opt-in. Grab a free key at [twelvelabs.io](https://twelvelabs.io) — there's a generous free tier. ## Key Features - Support for multiple video URL formats (including YouTube Shorts) - Language-specific transcript retrieval with automatic fallback - Optional timestamps for referencing specific moments - Built-in ad/sponsorship filtering (enabled by default) - Zero external dependencies for transcript fetching - Detailed metadata in responses ## Configuration To use with Claude Desktop, add this server configuration: ```json { "mcpServers": { "youtube-transcript": { "command": "npx", "args": ["-y", "@kimtaeyoon83/mcp-server-youtube-transcript"] } } } ``` To enable the optional `analyze_video` tool, add your TwelveLabs API key: ```json { "mcpServers": { "youtube-transcript": { "command": "npx", "args": ["-y", "@kimtaeyoon83/mcp-server-youtube-transcript"], "env": { "TWELVELABS_API_KEY": "your-twelvelabs-api-key" } } } } ``` ## Install via tool [mcp-get](https://github.com/michaellatman/mcp-get) A command-line tool for installing and managing Model Context Protocol (MCP) servers. ```shell npx @michaellatman/mcp-get@latest install @kimtaeyoon83/mcp-server-youtube-transcript ``` ## Awesome-mcp-servers [awesome-mcp-servers](https://github.com/punkpeye/awesome-mcp-servers) A curated list of awesome Model Context Protocol (MCP) servers. ## Development ### Prerequisites - Node.js 18 or higher - npm or yarn ### Setup Install dependencies: ```bash npm install ``` Build the server: ```bash npm run build ``` For development with auto-rebuild: ```bash npm run watch ``` ### Testing ```bash npm test ``` ### Debugging Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector for development: ```bash npm run inspector ``` ## Running evals The evals package loads an mcp client that then runs the index.ts file, so there is no need to rebuild between tests. You can load environment variables by prefixing the npx command. Full documentation can be found [here](https://www.mcpevals.io/docs). ```bash OPENAI_API_KEY=your-key npx mcp-eval src/evals/evals.ts src/index.ts ``` ## Error Handling The server implements robust error handling for common scenarios: - Invalid video URLs or IDs - Unavailable transcripts - Language availability issues - Network errors ## Usage Examples 1. Get transcript by video URL: ```typescript await server.callTool("get_transcript", { url: "https://www.youtube.com/watch?v=VIDEO_ID", lang: "en" }); ``` 2. Get transcript by video ID: ```typescript await server.callTool("get_transcript", { url: "VIDEO_ID", lang: "ko" }); ``` 3. Get transcript from YouTube Shorts: ```typescript await server.callTool("get_transcript", { url: "https://www.youtube.com/shorts/VIDEO_ID" }); ``` 4. Get transcript with timestamps: ```typescript await server.callTool("get_transcript", { url: "VIDEO_ID", include_timestamps: true }); ``` 5. Get raw transcript without ad filtering: ```typescript await server.callTool("get_transcript", { url: "VIDEO_ID", strip_ads: false }); ``` 6. How to Extract YouTube Subtitles in Claude Desktop App ```
