概要

What is YouTube Comment Downloader MCP Server?

A Model Context Protocol (MCP) server that provides AI systems with the ability to download and analyze YouTube video comments without requiring API keys. It uses web scraping, so no authentication is needed.

How to use YouTube Comment Downloader MCP Server?

Install dependencies with uv venv && source .venv/bin/activate && uv pip install -e ., test with python test_server.py, and run the server with python src/server.py. For MCP clients (e.g., Claude Desktop), add a configuration block using uv as the command pointing to src/server.py. The server exposes four tools: download_youtube_comments, get_comment_stats, search_comments, and get_top_comments_by_likes.

FAQ from YouTube Comment Downloader MCP Server

What are the key limitations?

The data has a flat structure (no hierarchical reply threading), top-level and reply comments are mixed (~10%/90% split), scraping is rate limited (~30–90 seconds per 500–1,000 comments), and larger requests may time out. There are no API quotas, but YouTube's terms must be respected.

What parameters do the tools accept?

Common parameters: video_id, limit (1–10,000), and sort (0=popular, 1=recent). search_comments adds a search_term parameter. get_top_comments_by_likes accepts top_count (1–100) and sample_size (100–2,000, default 500).

How is context usage optimized?

The get_comment_stats tool returns only statistics and five sample comments, using approximately 200 tokens compared to roughly 25,000 tokens for the full comment data.

Is authentication or an API key required?

No. The server uses web scraping to retrieve comments, so no YouTube API key or authentication is needed.
