MCP server for integrating Omnisearch with LLMs
MCP Omnisearch MCP server is a hosted integration for AI assistants that speak the Model Context Protocol. MCP server for integrating Omnisearch with LLMs.
A Model Context Protocol (MCP) server that provides unified access to Tavily, Brave, Kagi, Exa AI, GitHub, Linkup, and Firecrawl through four consolidated tools.
Once MCP Omnisearch is connected, these are the calls the assistant has available:
web_search — Search the web with Tavily, Brave, Kagi, Exa, or Kagi Enrichmentai_search — Get sourced AI answers with Kagi FastGPT, Exa Answer, or Linkupgithub_search — The github_search tool exposed by this serverweb_extract — Extract, crawl, scrape, summarize, or find similar content with Tavily, Kagi, Firecrawl, or ExaYou will need 8 environment variables: TAVILY_API_KEY, KAGI_API_KEY, BRAVE_API_KEY, GITHUB_API_KEY, EXA_API_KEY, LINKUP_API_KEY, FIRECRAWL_API_KEY, FIRECRAWL_BASE_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
Among the search and retrieval options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. MCP Omnisearch's toolset — web_search, ai_search, github_search and 1 more — is a fair guide to whether it matches your workflow. It is maintained by spences10; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

The simplest web tool that matters — fetch any URL and get model-ready markdown back.
Industrial-strength web extraction — render, scrape, crawl and search entire sites into clean markdown.
Puppeteer-powered browser control that drives pages from the accessibility tree instead of pixels.
Search built for AI, not humans — semantic web search that returns model-ready content, plus code context.
Answers, not links — delegate questions to Perplexity's search-grounded models and get cited responses back.
Put 6,000+ pre-built scrapers at your assistant's fingertips through one MCP endpoint.
