Overview

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

A Node.js MCP server and CLI for English and Chinese web search.

Agent Search MCP starts without an API key. It returns compact multi-source evidence, records provider failures, and bounds work with request and evidence budgets. Paid providers run only when policy and credentials allow.

Install

npx -y agent-search-mcp

Requires Node.js >= 18.17. The default runtime does not require a browser, database, Python, or a search API account.

Connect an MCP client

Use this stdio configuration in MCP clients that accept mcpServers JSON, including Claude Desktop, Cursor, VS Code, and Windsurf:

{
"mcpServers": {
"agent-search": {
"command": "npx",
"args": ["-y", "agent-search-mcp"]
}
}
}

Claude Code and Codex can register the same npx -y agent-search-mcp stdio command through their MCP settings.

Add the optional Agent Skill

After connecting the MCP server, Agent Skills-compatible clients can install the repository-owned routing guide

Questions

What is the Agent Search MCP server?

Free-first Chinese and English web search MCP using zero-key sources and inspectable evidence.

What tools does Agent Search expose?

9 in total: 9 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Agent Search safe to connect to an agent?

No — not without reading the findings first. The audit graded it D (69/100) and found 2 critical or high issues in the source. Each one is listed on this page with the file and line it is on.

What credentials does Agent Search need?

It reads BOCHA_API_KEY, BRAVE_API_KEY, EXA_API_KEY, HTTP_ALLOW_UNAUTHENTICATED, HTTP_AUTH_TOKEN, LLM_JUDGE_API_KEY, OPENAI_API_KEY, OPENCODE_API_KEY, SERPER_API_KEY, TAVILY_API_KEY, TENCENT_WSA_API_KEY and YDC_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 Agent Search run?

It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as agent-search-mcp at 3.2.1.

How current is this page?

The grade is for one exact copy of the source (580c72dbdf01), read on 2026-10-07. The repository is watched and re-audited when it changes.
