MCP server for WebUplink

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

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.

Tools

`browse`

Browse a web page or execute tools on a page.

Parameter	Type	Description
`url`	string	URL to open a new browser session
`session_id`	string	Existing session ID to continue browsing
`tool`	string	Tool name to execute on the page
`params`	object	Parameters for the tool
`include_page_content`	boolean	Include detailed page content

`close_session`

Close a browser session to free resources.

Parameter	Type	Description
`session_id`	string	Session ID to close

Environment Variables

Variable	Required	Default	Description
`WEBUPLINK_API_KEY`	✅	—	Your WebUplink API key
`WEBUPLINK_BASE_URL`	—	`https://api.webuplink.ai`	API base URL
`PORT`	—	`3001`	Local HTTP transport port
`MCP_HTTP_HOST`	—	`127.0.0.1`	Local HTTP transport bind address
`MCP_HTTP_ALLOWED_HOSTS`	non-loopback HTTP only	loopback names	Comma-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.
