Claude Search MCP Server

MCP server that provides Claude web search functionality. Exposed over MCP by the claude search mcp mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

This MCP (Model Context Protocol) server provides web search capabilities using the Claude API. It allows LLMs to access up-to-date information from the web through a standardized interface.

• Web search tool using Claude's web search API
• Support for domain filtering (allowed and blocked domains)
• Configurable maximum results per search
• Automatic configuration from Claude Desktop config file

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

Configuration

You will need one environment variable: ANTHROPIC_API_KEY. 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.

• Node.js 18 or higher - An Anthropic API key with web search enabled - Claude Desktop app for testing

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the claude search mcp mcp server does with a few real requests.

When to reach for it

Plenty of search and retrieval servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. It is maintained by Doriandarko; worth a glance at recent repository activity before you build anything load-bearing on it.
