Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package @webuplink/mcp
Claude Code 
claude mcp add webuplink -e 'WEBUPLINK_API_KEY=<your webuplink_api_key>' -- npx -y @webuplink/mcp@0.1.1
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "webuplink": {
            "command": "npx",
            "args": [
                "-y",
                "@webuplink/mcp@0.1.1"
            ],
            "env": {
                "WEBUPLINK_API_KEY": "<your webuplink_api_key>"
            }

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "webuplink": {
      "command": "npx",
      "args": ["--yes", "--package", "@webuplink/mcp", "webuplink-mcp"],
      "env": {
        "WEBUPLINK_API_KEY": "wup_your_api_key"
      }
    }
  }
}

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "webuplink": {
      "command": "npx",
      "args": ["--yes", "--package", "@webuplink/mcp", "webuplink-mcp"],
      "env": {
        "WEBUPLINK_API_KEY": "wup_your_api_key"
      }
    }
  }
}

That's it — your AI can now browse and interact with any website.

Environment Variables

VariableRequiredDefaultDescription
WEBUPLINK_API_KEY✅—Your WebUplink API key
WEBUPLINK_BASE_URL—https://api.webuplink.aiAPI base URL
PORT—3001Local HTTP transport port
MCP_HTTP_HOST—127.0.0.1Local HTTP transport bind address
MCP_HTTP_ALLOWED_HOSTSnon-loopback HTTP onlyloopback namesComma-separated Host/Origin names accepted by the HTTP boundary

HTTP Transport

For a local Streamable HTTP endpoint, invoke the HTTP binary explicitly:

WEBUPLINK_API_KEY=wup_... npx --yes --package @webuplink/mcp webuplink-mcp-http

The server accepts stateless MCP POST requests at /mcp and listens on 127.0.0.1:3001 by default. Set PORT to change the port.

Binding to a non-loopback interface is an explicit opt-in:

WEBUPLINK_API_KEY=wup_... MCP_HTTP_HOST=0.0.0.0 \
  MCP_HTTP_ALLOWED_HOSTS=mcp.internal.example \
  npx --yes --package @webuplink/mcp webuplink-mcp-http

The listener rejects missing or unlisted Host headers before allocating MCP resources and applies the same allowlist to browser Origin headers. This protects the loopback default from DNS rebinding; it is not client authentication. Every accepted request still uses the single configured WEBUPLINK_API_KEY, so do not expose the listener directly to an untrusted network. Put an authenticated boundary in front of it for controlled remote use.

Frequently asked questions

What is WebUplink?

Give any MCP client the ability to browse and interact with the web via WebUplink.

How do I install WebUplink?

It runs on your machine. In Claude Code: claude mcp add webuplink -e 'WEBUPLINK_API_KEY=<your webuplink_api_key>' -- npx -y @webuplink/mcp@0.1.1. For other clients, paste the JSON configuration from this page into their MCP settings.

Does WebUplink need an API key?

Yes. It expects WEBUPLINK_API_KEY, which you set in its configuration.

Is WebUplink open source?

Yes. Its code is on GitHub under the MIT license.

Who maintains WebUplink?

It is published by webuplink-dev. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
