Install Steadyfetch actors on Apify MCP in Devin Desktop

What you need first

Devin Desktop, installed.
Nothing else: the server runs on its publisher's machines and Devin Desktop connects to it.
Your own value for YOUR_AUTHORIZATION.

Steps

Open ~/.config/devin/mcp_config.json, or create it. On Windows it is %APPDATA%\devin\mcp_config.json.
Add this block. If the file already has mcpServers, add only the entry inside it.

{
  "mcpServers": {
    "steadyfetch-actors": {
      "url": "https://mcp.apify.com/?tools=fetch-actor-details,steadyfetch/keyword-search-volume-scraper,steadyfetch/instagram-reel-transcript-scraper,steadyfetch/instagram-post-likers-scraper,steadyfetch/instagram-profile-details-scraper,steadyfetch/facebook-ads-transcript-scraper,steadyfetch/media-transcriber,steadyfetch/reddit-scraper,steadyfetch/linkedin-sales-navigator-scraper,steadyfetch/instagram-profile-posts,steadyfetch/instagram-keyword-reels-scraper,steadyfetch/facebook-reels-scraper,steadyfetch/google-trends-scraper,steadyfetch/instagram-comments-scraper,steadyfetch/youtube-transcript-scraper,steadyfetch/youtube-channel-transcripts,steadyfetch/instagram-followers-scraper,steadyfetch/linkedin-posts-scraper,steadyfetch/instagram-similar-profiles-scraper,steadyfetch/youtube-comments-scraper,steadyfetch/competitor-keywords-scraper,steadyfetch/multi-job-board-scraper,steadyfetch/amazon-search-scraper,steadyfetch/google-keyword-suggest-scraper,steadyfetch/amazon-bestsellers-scraper,steadyfetch/google-trends-now-scraper,steadyfetch/breakout-keywords-scraper,steadyfetch/amazon-seller-scraper,steadyfetch/indeed-jobs-scraper,steadyfetch/amazon-product-scraper,steadyfetch/social-trends-scraper,steadyfetch/google-ads-video-transcript-scraper,steadyfetch/glassdoor-jobs-scraper,steadyfetch/company-jobs-by-domain,steadyfetch/google-ads-creative-text-scraper,steadyfetch/tiktok-ads-transcript-scraper,steadyfetch/google-jobs-scraper,steadyfetch/linkedin-ads-transcript-scraper,steadyfetch/instagram-hashtag-scraper,steadyfetch/instagram-post-details-scraper,steadyfetch/linkedin-jobs-scraper",
      "headers": { "Authorization": "YOUR_AUTHORIZATION" }
    }
  }
}

Replace YOUR_AUTHORIZATION with your own value.
Save the file and restart Devin Desktop.

Check it worked

Ask Devin Desktop: List the tools of steadyfetch-actors.

If it does not start

401 Unauthorized: The endpoint wants a sign-in or a key. Sign in when Devin Desktop asks, or check the value in place of the placeholder.
The server starts, but its tools fail: A YOUR_… placeholder is still in the config, or its value is wrong.
Nothing changes after a restart: The file is not valid JSON any more. Look for a missing comma where the block was added.
