Best For

Contract is available with explicit auth and schema references.

Not Ideal For

@modelcontextprotocol/server-filesystem is not ideal for teams that need stronger public trust telemetry, lower setup complexity, or more explicit contract coverage before production rollout.

Setup snapshot

git clone https://github.com/zubayr-ahmad/YoutubeAgent.git

1
Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

YouTube Agent — MCP Server for YouTube Interaction

An extensible Model Context Protocol (MCP) server‑agent that lets you interact with YouTube videos: fetch transcripts, ask questions, generate summaries, extract key points, create note files, and even manage folders and files — all within a scoped, secure directory.

🚀 Features

🎥 Transcript Fetching: Retrieve closed captions/subtitles for a given YouTube video URL.
❓ Q&A: Answer user questions based on transcript content using keyword matching.
✍️ Summarization: Generate concise summaries of video content via word‑frequency scoring.
📌 Key Point Extraction: Identify potential key points using frequency analysis and trigger phrases.
🗒️ Notes Creation: Produce a structured .txt file (title, summary, key points, transcript excerpts) in a notes/ subdirectory.
💬 Chat Context: Maintain a short conversation history for the chat_with_video tool.
🔒 Security: Restrict all file‑system operations (creating/updating/deleting) to a single “allowed” directory passed at startup.
⚙️ MCP Compliance: Implements an MCP server with @modelcontextprotocol/sdk over stdio, exposing tools for programmatic use.
📂 File & Folder Management: Create, delete, or overwrite folders and files within the allowed directory to organize notes and transcripts.

📁 Directory Structure

When you launch the agent, you specify one allowed directory (e.g. ~/youtube-agent-data). Inside it:

<allowed-dir>/
├─ notes/        ← Generated `.txt` note files
└─ (optional)    ← You may add subdirectories or store raw transcripts here

The agent will auto‑create the notes/ folder if it doesn’t exist.

🛠️ Tools & Capabilities

| Tool | Description | |------------------------|--------------------------------------------------------------------------------------| | fetch_transcript | Download captions/subtitles for a YouTube video. | | ask_question | Answer a user’s question by searching the transcript text. | | summarize_video | Produce a high‑level summary based on transcript word frequencies. | | extract_key_points | Identify salient points using keyword triggers and frequency analysis. | | create_notes | Generate and save a .txt file with title, summary, key points, and excerpts. | | chat_with_video | Maintain conversational context across multiple Q&A calls. | | create_directory | Create a new folder anywhere under the allowed directory (recursive). | | delete_file | Remove a file from within the allowed directory. | | write_file | Create or overwrite a file in the allowed directory (used for note and transcript). |

⚙️ Setup & Running

1. Clone the repository

git [email protected]:zubayr-ahmad/YoutubeAgent.git
cd YoutubeAgent

2. Install dependencies

npm install
pnpm install

3. Build the project

npm run build

4. Run the MCP Agent (TypeScript via ts‑node)

npx -y supergateway --stdio "node ./dist/index.js ." --port 8000 --baseUrl "http://localhost" --ssePath /sse --messagePath /message --cors "*"

5. (Optional) Expose Locally with ngrok

ngrok http 8000

📦 Tech Stack

Node.js & TypeScript
@modelcontextprotocol/sdk for MCP server integration
Zod for request/input validation
youtube‑transcript (or node-fetch) for fetching captions
diff & minimatch for future extensions

🧰 Development Tips

All file‑system operations are gated by validatePath() to enforce your allowed directory.
Conversation context for chat_with_video is kept in memory—consider persisting if you need long‑term history.
Extend the CallToolRequestSchema switch‑case to add new tools (e.g., advanced NLP, embedding-based search).
