What it does

This MCP server provides real-time web search and page fetching through Linkup's API, enabling Claude to access current information, news, and data from across the web. It supports natural language queries with configurable search depth—standard for direct answers like weather or stock prices, deep for multi-source research—and can filter results by domain and date range. Page fetches optionally render JavaScript, extract images, and return raw HTML.

Who it's for

Backend engineers and AI researchers building applications where Claude needs access to real-time information. Developers integrating Claude into chat systems or agents where responses must reference current events, live data, or recent publications rather than relying on training-data-only knowledge.

Common use cases

• Answer questions about current events, stock prices, weather, or today's news via real-time search
• Fetch and summarize recent articles or blog posts for fact-checking and research
• Search domain-specific sources (academic papers, news outlets, competitors) with include/exclude domain filters
• Extract content from dynamic pages that require JavaScript rendering
• Retrieve time-sensitive information (flight prices, product availability) with date-range filtering

Setup pitfalls

• Requires a free Linkup API key from app.linkup.so; all requests fail without valid credentials
• Remote HTTP endpoint requires the API key either as a Bearer token in headers (preferred) or in the query parameter ?apiKey=...—verify your MCP client supports your chosen method
• Local stdio installs via npx pass the API key as a command argument apiKey=LINKUP_API_KEY, not as an environment variable
