Common questions

Is Comment Scraper safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.3) reached the registry 8 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

comment-scraper-mcp

Ask Claude about the Reddit and Hacker News threads you exported with Comment Scraper, without pasting them in.

This is a small MCP server. It reads the JSON files the Comment Scraper browser extension saves to your Downloads folder and gives Claude (or any MCP client) four tools to list, read and search them. Comments keep the same numbers as the extension's Markdown export, like [c12], so when Claude quotes a comment you can find it in the file.

It runs on your computer, only reads files, and makes no network requests.

Before you start

Install the Comment Scraper extension from the Chrome Web Store.
Export a thread and pick JSON, one row per comment or JSON, replies nested. CSV and Markdown files aren't read.
Have Node.js 20 or newer.

Install

Claude Code

claude mcp add comment-scraper -- npx -y comment-scraper-mcp

Claude Desktop: open Settings → Developer → Edit Config and add:

"mcpServers": { "comment-scraper": { "command": "npx", "args": ["-y", "comment-scraper-mcp"] } } }

Restart Claude Desktop afterwards. Other MCP clients (Cursor, Windsurf and so on) take the same command: npx -y comment-scraper-mcp.

As a Claude Code plugin: the plugin folder bundles the server, pinned to a release, with a skill that tells Claude how to cite comments. This repository doubles as a plugin marketplace:

claude plugin install comment-scraper --marketplace supertj/comment-scraper-mcp

Use the plugin or claude mcp add, not both, or Claude sees every tool twice.

As a Hermes Agent plugin: the same folder works in Hermes Agent. The install steps are in the plugin README.

Pi: this package is also a Pi package. Installing it gives Pi the server and the same skill the Claude plugin uses:

pi install npm:comment-scraper-mcp

Start a new Pi session and ask about your exports. Pi starts the server from the installed package, so nothing is downloaded at run time, and /mcp shows whether it connected. You need Pi 0.99 or newer, the first version with MCP support. To read another folder, set COMMENT_SCRAPER_DIRS in the shell you start Pi from. If you already added comment-scraper-mcp to Pi's mcp.json by hand, remove that entry, unless it's named comment-scraper, in which case Pi uses it in place of the package's.

Where it looks

By default it reads your Downloads folder and the folders directly inside it, so moving exports into a project folder there is fine. To read somewhere else, pass one or more folders:

claude mcp add comment-scraper -- npx -y comment-scraper-mcp --dir ~/Research/reddit

or set COMMENT_SCRAPER_DIRS (folders separated by :, or ; on Windows). Files are recognised by their content, so renaming them is fine. If you export the same thread twice, the newest export is used.

Tools

Tool	What it does
`list_threads`	Your exported threads, newest first, with how many comments were fetched and how many the site reports
`read_thread`	A thread as numbered Markdown, 200 comments at a time, optionally only comments above a score
`search_comments`	Comments containing all of your words, across every export or one thread, highest score first
`get_comment`	One comment with the replies it answers and the replies to it

Things to ask

"List my exported threads."
"Read the CRM thread and group the complaints about pricing. Cite comment numbers."
"Search my exports for 'switched from' and summarise what people moved to."
"Show c41 in context."

Privacy

The server reads JSON files in the folders above and nothing else. It doesn't write, move or delete files, and it doesn't connect to the internet. What you ask Claude, and the comments Claude reads through these tools, go to Anthropic or whichever model provider your client uses, under their terms. Exports from the extension don't contain usernames.
