  Status: explained. The issue is closed. The maintainers' recommended fix is to skip the local apify-mcp-server extension and connect Claude Desktop to the remote Apify MCP server, because Claude Desktop can behave inconsistently with the extension.

  The setup confirmed as working by multiple users in the thread:

  1. Go to https://mcp.apify.com/ (opens external site) ↗ and get the link for the tools you want.
  2. In Claude Desktop: Settings → Connectors → Add custom connector, give it a name, and use https://mcp.apify.com as the URL.
  3. Complete the browser-based OAuth flow to verify the connection.

  One user reported success by adding the tool link from mcp.apify.com as a custom connector along with the Apify API token. If you prefer a JSON config, a maintainer proposed using the remote server through mcp-remote:

  {
    "mcpServers": {
      "apify": {
        "command": "npx",
        "args": [
          "-y",
          "mcp-remote",
          "https://mcp.apify.com/",
          "--header",
          "Authorization: Bearer <YOUR_API_TOKEN>"
        ]
      }
    }
  }
  

  One user also got a working connection simply by uninstalling the extension and trying again, after which it connected to Claude Desktop. If the error persists, the maintainer asked for logs via the bug report template and pointed to the troubleshooting section in the apify/apify-mcp-server README and the Apify docs.

  What @YagneshKhamar tried on GitHub (Worked)

  Got the tool link from https://mcp.apify.com/ (opens external site) ↗, added it as a custom connector in Claude Desktop with a name, link, and API token, then completed the browser verification. The maintainer confirmed this approach and another user reported it worked.

  What @jirispilka tried on GitHub (Outcome unclear)

  A maintainer suggested using the remote Apify MCP via npx mcp-remote https://mcp.apify.com/ --header "Authorization: Bearer <YOUR_API_TOKEN>" in the mcpServers config, but the thread doesn't show this being tried or confirmed.
