Kagi MCP Server

What is Kagi MCP Server?

A Model Context Protocol (MCP) server that integrates with Kagi’s search and summarizer APIs, allowing Large Language Models (LLMs) to search the web and summarize web pages using Kagi’s privacy-focused search and AI capabilities.

How to use Kagi MCP Server?

Install by cloning the repository and building with Go (requires Go 1.18+ and a Kagi API key). Run with -t stdio for subprocess communication or -t sse -port 8080 for an HTTP server. Provide the API key via the KAGI_API_KEY environment variable or the -api-key flag. Integrate with Claude by adding a JSON entry under mcpServers in Claude’s configuration.

FAQ from Kagi MCP Server

What is the Kagi MCP Server and how does it differ from direct API usage?

It provides a standardized MCP interface so LLMs can call Kagi’s search and summarizer APIs as tools, without the LLM needing direct API credentials or custom code.

What dependencies or runtime requirements are needed?

Go 1.18+ for building from source, and a Kagi API key (available to Kagi subscribers). No external services beyond Kagi’s APIs are required.

Where does data live and what are the transport options?

Data is sent to and from Kagi’s servers. The server supports two transports: stdio (subprocess communication) and SSE (HTTP server, default port 8080).

How do I authenticate and configure the API key?

Set the KAGI_API_KEY environment variable or pass it via the -api-key command-line flag. The key is used to authenticate all requests to Kagi’s APIs.

Can I use the Kagi MCP Server with Claude?

Yes. Start the server in stdio mode and add a matching mcpServers configuration in Claude’s JSON settings, providing the command and API key.
