This MCP server provides web search capabilities using Linkup's advanced search API. It allows AI assistants and development tools to perform natural language queries and retrieve up-to-date search results with source citations. You can run the server via npx, either by passing your API key directly or by setting the LINKUP_API_KEY environment variable. Once running, clients can query the MCP interface to perform semantic web searches and obtain relevant results from Linkup's search API.

Prerequisites:

• Node.js and npm installed on your system
• Access to the Internet to fetch the MCP server package from npm

Installation steps:

1. Ensure you have Node.js and npm installed. Verify with:

node -v
npm -v

2. Run the MCP server directly using npx (no local install required):

npx -y linkup-mcp-server --api-key=YOUR_LINKUP_API_KEY

3. Alternatively, export your API key as an environment variable and run without the inline flag:

export LINKUP_API_KEY=YOUR_LINKUP_API_KEY
npx -y linkup-mcp-server

4. (Optional) If you are integrating with a client, configure the mcp_config as shown above in your MCP client setup to point to this server.

Notes:

• This JS version is deprecated in favor of the TypeScript/Node.js version. Consider upgrading to the maintained TypeScript version at the linked repository.
• The server requires a Linkup API key. You can supply it via the API key flag or the LINKUP_API_KEY environment variable.
• Default base URL for the API is https://api.linkup.so/v1 unless overridden by --base-url.
• If you encounter rate limits or authentication errors, ensure your API key is valid and has the necessary permissions.
• The MCP client documentation will provide specifics on how to integrate and call MCP endpoints from your app.
