Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

[](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

Install the published server with MCPick:

npx mcpick add \
--name mcp-omnisearch \
--command npx \
--args=-y,mcp-omnisearch

MCPick defaults to Claude Code. Use --client and --scope to target another client or add the server to the current repository:

npx mcpick add \
--name mcp-omnisearch \
--command npx \
--args=-y,mcp-omnisearch \
--client vscode \
--scope project

See Deployment for supported clients and provider credential storage options.

To run from source instead:

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

Providers without keys are skipped and the rest keep working. If your client supports environment-variable expansion, reference keys instead of storing their values in the MCP configuration:

{
"mcpServers": {
"mcp-omnisearch": {
"command": "npx",
"args": ["-y", "mcp-omnisearch"],
"env": {
"TAVILY_API_KEY": "${TAVILY_API_KEY}",
"EXA_API_KEY": "${EXA_API_KEY}"
}
}
}
}

Add only the provider keys you use. Expansion syntax and secret storage are client-specific; see Deployment for secure options and plaintext fallback guidance.

Questions

What is the Omnisearch MCP server?

🔍 A Model Context Protocol (MCP) server providing unified access to multiple search engines (Tavily, Brave, Kagi, Exa), AI tools (Kagi FastGPT, Exa, Linkup), and content extraction services (Firecrawl, Tavily, Kagi). Includes GitHub search. All through a single interface.

What tools does Omnisearch expose?

3 in total: 3 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Omnisearch safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Omnisearch need?

It reads BRAVE_API_KEY, EXA_API_KEY, FIRECRAWL_API_KEY, GITHUB_API_KEY, KAGI_API_KEY, LINKUP_API_KEY and TAVILY_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does Omnisearch run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as mcp-omnisearch at 0.1.0.

How current is this page?

The grade is for one exact copy of the source (ed244f9674a8), read on 2026-10-03. The repository is watched and re-audited when it changes.
