Kagi MCP

by yuki-yano

Kagi MCP (Node.js)

A Node.js implementation of the Kagi Model Context Protocol (MCP) server. This provides a more stable alternative to the official Python implementation, especially when running multiple instances.

Features

  • Search web content using Kagi Search API
  • Summarize documents, videos, and audio using Kagi Summarizer API
  • No port conflicts when running multiple instances
  • Full compatibility with Claude Desktop

Prerequisites

  • Node.js 18 or higher
  • Kagi API key (request from support@kagi.com)
  • Note: The Search API is in closed beta. You may need to request access separately.

Installation

No installation needed! Claude Desktop can run the package directly using npx.

Method 2: Install from npm

npm install -g kagi-mcp

Or use it directly with npx:

npx kagi-mcp

Method 3: Install from GitHub directly

npm install -g github:yuki-yano/kagi-mcp

Method 4: Install from source

git clone https://github.com/yuki-yano/kagi-mcp.git cd kagi-mcp npm install npm run build npm link

Configuration

Environment Variables

  • KAGI_API_KEY (required): Your Kagi API key
  • KAGI_SUMMARIZER_ENGINE (optional): Summarization engine - cecil (default), agnes, daphne, or muriel

Claude Desktop Configuration

Add the following to your Claude Desktop config file:

MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{ "mcpServers": { "kagi": { "command": "npx", "args": ["kagi-mcp"], "env": { "KAGI_API_KEY": "your-kagi-api-key" } } } }

This method automatically downloads and runs the latest version from npm without requiring manual installation.

Method 2: Using globally installed package
{ "mcpServers": { "kagi": { "command": "kagi-mcp", "env": { "KAGI_API_KEY": "your-kagi-api-key" } } } }

Claude Code Configuration

To use with Claude Code CLI, run the following command:

claude mcp add kagi -s user -e KAGI_API_KEY="your-kagi-api-key" -- npx kagi-mcp

This will:

  • Add the Kagi MCP server to your Claude Code configuration
  • Set it up at the user level (-s user)
  • Configure your API key as an environment variable
  • Use npx to automatically download and run the latest version from npm

You can also use the MCP inspector for debugging:

# Method 1: Using npx (requires npm package to be published) KAGI_API_KEY="your-kagi-api-key" npx @modelcontextprotocol/inspector npx kagi-mcp # Method 2: Using local installation (more reliable) npm install -g kagi-mcp KAGI_API_KEY="your-kagi-api-key" npx @modelcontextprotocol/inspector kagi-mcp # Method 3: Using source build KAGI_API_KEY="your-kagi-api-key" npx @modelcontextprotocol/inspector node dist/index.js

Usage

The MCP server provides two tools:

kagi_search_fetch

Search the web using Kagi Search API.

{ "queries": ["array of search queries"] }

kagi_summarizer

Summarize content from a URL.

{ "url": "https://example.com/article", "summary_type": "summary" | "takeaway", // optional "target_language": "EN" // optional }

Development

# Install dependencies npm install # Run in development mode npm run dev # Build npm run build # Run built version npm start

Troubleshooting

"Malformed authorization token" error

This error indicates that your API key is invalid or not properly formatted. Make sure:

  • You have a valid Kagi API key from support@kagi.com
  • The key is correctly set in your environment variable
  • You're not adding extra quotes or spaces around the key

"401 Unauthorized" error for Search API

The Search API is in closed beta. You may need to:

  1. Request access to the Search API separately from support@kagi.com
  2. Ensure your API key has the necessary permissions

Testing your API key

You can test your API key using the included test script:

KAGI_API_KEY="your-api-key" node test-api.js
