About MCP Server

What is MCP Server: Blazing Fast & Secure Local Web Search?

MCP Server is a specialized tool built on the Model Context Protocol (MCP), designed to enable lightning-fast local web searches directly from your machine. Unlike traditional search engines, it operates securely within your environment, leveraging headless browser technology and advanced content extraction to deliver precise results. Whether you're a developer debugging code or a researcher sifting through data, this server gives you granular control over how web content is fetched, filtered, and processed.

How to Use MCP Server: Blazing Fast & Secure Local Web Search?

Getting started is straightforward. First, ensure you have Bun runtime installed. Run bun install to fetch dependencies, then execute bun run setup.ts to configure the server within your MCP ecosystem. To perform searches, use the local_web_search tool with parameters like query for your search term and excludeDomains to block specific sites. Advanced options like truncate let you control content length, while proxy supports privacy-focused requests.
