## About

# mcp-omnisearch

[](https://viteplus.dev)
[](https://vitest.dev)

A Model Context Protocol (MCP) server that provides unified access to
Tavily, Brave, Kagi, Exa AI, GitHub, Linkup, and Firecrawl through
four consolidated tools.

  

## Quick start

```bash
pnpm install
pnpm run build
node ./dist/index.js
```

Configure the server in your MCP client with whichever provider keys
you have. Providers without keys are skipped and the rest keep
working.

		"mcp-omnisearch": {
			"command": "node",
