mcp-omnisearch

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

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.
