What it does

Give channels, or a search term with a subscriber range. For each channel you get its stats and any address it publishes in plain text on its about page or linked website, with the page that shows it.

All of the work runs on Apify. This package is a thin client that starts the actor run, waits for it, and hands back the dataset rows.

Quick start

You need Node.js 18 or newer and an Apify account with an API token.

Add this to your Claude Desktop config (claude_desktop_config.json), Cursor, or any MCP client:

{
  "mcpServers": {
    "mamba-youtube-channel-email-finder": {
      "command": "npx",
      "args": [
        "-y",
        "@mambalabsdev/mcp-youtube-channel-email-finder"
      ],
      "env": {
        "APIFY_TOKEN": "your-apify-token"
      }
    }
  }
}

Restart the client. The find_youtube_channel_emails tool appears.

Prerequisites

Node.js 18 or newer.
An Apify API token from console.apify.com/account/integrations, set as APIFY_TOKEN. The server lists its tool without a token; a call needs one.

Example prompts

"Find the published business email for @mkbhd."
"Find home espresso channels with 10,000 to 500,000 subscribers and their published emails."
"Which of these YouTube channels publish a contact address?"

Tool

find_youtube_channel_emails. One tool. Example arguments:

{
  "channels": [
    "@mkbhd"
  ]
}

Inputs

Every buyer facing input of the actor. Omitted inputs take the actor's own defaults.

Input	Type	Required	Description
`channels`	array	no	Channel URLs, @handles, or UC channel IDs, up to 500 a run. Clay users: wrap a column in a one item list.
`search_terms`	array	no	Optional. Themes to find channels by, such as home espresso. Search results come from YouTube's channel search, up to the maximum per search below.
`max_channels_per_search`	number	no	Number as text, 1 to 200. Default 20.
`min_subscribers`	number	no	Optional. Number as text. YouTube rounds subscriber counts, so this filter is approximate.
`max_subscribers`	number	no	Optional. Number as text. YouTube rounds subscriber counts, so this filter is approximate.
`check_websites`	boolean	no	no (default) or yes. yes reads the home page and one contact or about page on a site the channel links to, obeying robots.txt. It finds more addresses and costs more pages per run.
`videos_to_check`	number	no	Number as text, 0 to 10. Default 0, which is off. YouTube answered most video page reads with a sign in gate in testing, so this finds little and takes longer. Read only when no address has been found yet.
`check_all_sources`	boolean	no	no (default) stops at the first source with an address. yes reads them all, which takes longer.
`max_charge_usd`	string	no	Optional. The run stops before a charge would pass this amount.
