Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

A Model Context Protocol (MCP) server that provides web search and page fetching capabilities through Linkup's advanced API. This server enables AI assistants like Claude to perform intelligent web searches with natural language queries and fetch content from any webpage, accessing real-time information from trusted sources across the web.

Features

  • 🔍 Real-time Web Search: Search the web for current information, news, and data
  • 🧠 Deep Research: Start long-running, multi-source research tasks and poll for results
  • 🌐 Page Fetching: Fetch and extract content from any webpage
  • 🎯 Natural Language Queries: Use full questions for best results
  • 📊 Flexible Search Depth:
  • standard - For queries with direct answers
  • deep - For complex research requiring analysis across multiple sources
  • 🎯 Result Filtering: Restrict by domain (includeDomains / excludeDomains), date range (fromDate / toDate), and maxResults
  • 🖼️ Image Results: Optional includeImages for search and extractImages for fetch
  • 🖥️ JavaScript Rendering: Optional JS rendering for dynamic content
  • 📄 Raw HTML: Optional includeRawHtml for fetch when you need the unprocessed page
  • ⚡ Fast: Powered by Linkup's optimized infrastructure

Installation

  • Cursor, VSCode, Claude Code, Codex, or another MCP compatible client
  • Linkup API key

What tools does Linkup expose?

4 in total: 4 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Linkup safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Linkup need?

No credential environment variables were found in its source, so it appears to need none.

How does Linkup run?

It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as linkup-mcp-server at 3.0.0.

How current is this page?
