Overview

Description from the maker (original English)

Read your Comment Scraper exports of Reddit and Hacker News threads. Local and read-only.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: COMMENT_SCRAPER_DIRS

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

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

Run this in your terminal

claude mcp add comment-scraper --env COMMENT_SCRAPER_DIRS=your-value -- npx -y comment-scraper-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

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

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "comment-scraper": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "comment-scraper-mcp"
      ],
      "env": {
        "COMMENT_SCRAPER_DIRS": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • COMMENT_SCRAPER_DIRS env
    Folders to read exports from, separated by ':' (';' on Windows). Defaults to your Downloads folder and the folders directly inside it.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

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

  1. Install the Comment Scraper extension from the Chrome Web Store.
  2. Export a thread and pick JSON, one row per comment or JSON, replies nested. CSV and Markdown files aren't read.
  3. 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

ToolWhat it does
list_threadsYour exported threads, newest first, with how many comments were fetched and how many the site reports
read_threadA thread as numbered Markdown, 200 comments at a time, optionally only comments above a score
search_commentsComments containing all of your words, across every export or one thread, highest score first
get_commentOne 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.
