Paste a YouTube video link. RouterGrowth scrapes the comments under it and returns rows with text, author, likes, reply count and when each was posted. Point it at a product launch video and the agent gets the feature requests, bug reports and objections viewers left, with no API quota or scraper code.

Ten comments under Figma's code layers launch video: a question about MCP support, a missing toolbar option and a sceptical take with 17 likes.
Step by step
Add the MCP server to Claude, ChatGPT, Claude Code, Codex or Cursor. A new workspace starts with $1 of credit, enough to run this example many times.
Paste the link of a launch, a review or a competitor's demo, and how many comments to read.
social.comments returns each one with text, author, likes, replies and posting time.
Ask the agent to tag each comment as a question, a request, a bug or an objection.
Price
List prices on YouTube, read from the catalog when this page was built. The exact figure is quoted before every run, and a monthly plan lowers it.
In practice
You describe the job; the agent picks the calls, shows the price and runs them.
Scrape 200 comments under Figma's latest launch video and group them into feature requests, bugs and objections.
Read the comments under a competitor's last three uploads and list every complaint about pricing.
Find YouTube reviews of our product and pull the comments under the top two.
Connect
One MCP server for Claude, ChatGPT, Claude Code, Codex and Cursor, or the same call over the CLI and REST with the input above.
claude mcp add --transport http routergrowth https://api.routergrowth.com/mcp
npm install -g routergrowth && routergrowth setup
routergrowth run -c social.comments -i '{"url": "https://www.youtube.com/watch?v=ukY9Dvwm7Gc", "platform": "youtube", "limit": 10}'curl -X POST https://api.routergrowth.com/v1/run \

Comments under a launch video are early product feedback; here a missing toolbar option showed up in the first ten.
Posting time comes back as YouTube shows it, such as "2 days ago"; date the run if you store it.
YouTube's pages and limits are handled behind the call. A video with no comments returns no rows and no charge.
FAQ
No. The call uses your RouterGrowth key, with no Google Cloud project or quota.
Each comment carries its reply count, so you can see which ones started a thread.
Pass the Short's link as the URL the same way as for a video.
Set limit to what you need. The charge covers the comments returned.
