Do I need a YouTube API key?
No, for fetching subtitles and channel metadata. A free API key is required only for video search and comment collection (daily quota of 10,000 units).

A server that integrates YouTube subtitles, comments, and channel data as research sources for AI assistants via the Model Context Protocol (MCP). It works with any MCP‑capable AI client (Claude Desktop, Cursor, Windsurf, Cline, etc.) and requires no API key for subtitle and channel analysis; an optional YouTube Data API key unlocks video search and comment analysis.
Install it with uvx youtube-research-mcp (recommended, requires uv) or pip install youtube-research-mcp. Then configure your MCP client (e.g., Claude Desktop’s claude_desktop_config.json) with the command uvx and arguments ["youtube-research-mcp"]. To use all features, set the environment variable YOUTUBE_API_KEY. Restart the client after configuration.
safety_notice field.No, for fetching subtitles and channel metadata. A free API key is required only for video search and comment collection (daily quota of 10,000 units).
Yes. The server only fetches data from YouTube and caches it locally. It never sends collected data to external servers, never calls any LLM or AI API, never accesses files outside its cache directory, and never executes shell commands. Source code is public on GitHub.
Subtitles are cached for 30 days, comments for 6 hours, search results for 2 hours, and video metadata permanently. Caching reduces duplicate API calls.
Default locations: macOS `~/Library/Application Support/youtube-research-mcp/cache.db`, Windows `%APPDATA%\youtube-research-mcp\cache.db`, Linux `~/.local/share/youtube-research-mcp/cache.db`. Override with the `YOUTUBE_RESEARCH_CACHE_DB` environment variable.
Use `uvx youtube-research-mcp` (recommended, requires `uv`) or `pip install youtube-research-mcp`. For pip installations, set the MCP client’s command to `"youtube-research-mcp"` with empty `args`.
