Kagi MCP Server

Kagi Search and Universal Summarizer integration through the Model Context Protocol (MCP). Works with Claude Code, Claude Desktop, Cursor, Zed, and any MCP-compatible client.

This repository provides:

• kagiapi - Standalone Rust client library for Kagi's APIs (crates.io)
• kagi-mcp-server - MCP server binary exposing Kagi tools to AI assistants (crates.io)
• Zed extension - Direct integration with the Zed editor via the extension marketplace

Prerequisites

Get Kagi API access:

1. Request API access by emailing support@kagi.com (currently in closed beta)
2. Get your API key from Kagi Settings

Quick Start

Install via cargo

cargo install kagi-mcp-server

Install via npm (pre-built binaries, no Rust toolchain needed)

npx -y kagi-mcp-server@latest

Zed Editor

1. Install the extension: Extensions > Search "Kagi MCP Server" > Install
2. Add to your Zed settings:

{
  "context_servers": {
    "kagimcp": {
      "settings": {
        "kagi_api_key": "YOUR_KAGI_API_KEY_HERE",
        "kagi_summarizer_engine": "cecil"
      }
    }
  }
}

Claude Code (CLI)

claude mcp add -s user kagi -e KAGI_API_KEY="<YOUR-KEY-HERE>" -- kagi-mcp-server

Claude Desktop / Cursor / Other MCP Clients

See the kagi-mcp-server documentation for detailed configuration examples for all supported clients.

Usage Examples

Ask your AI assistant:

• "Search for the latest AI safety research"
• "Find recent climate change news"
• "Summarize this article: https://example.com/article"
• "Summarize this YouTube video: https://youtube.com/watch?v=..."

Using the Kagi API Library

If you want to use Kagi's APIs in your own Rust project:

[dependencies]
kagiapi = "0.0.30"

use kagiapi::KagiClient;

#[tokio::main]
async fn main() -> Result<(), kagiapi::Error> {
    let client = KagiClient::new("your-api-key");
    let results = client.search("rust programming", Some(10)).await?;
    Ok(())
}

See the kagiapi documentation for full API reference.

Troubleshooting

API errors?

• Ensure you have Kagi Search API access (closed beta)
• Double-check your API key

Server not responding?

• Test manually: KAGI_API_KEY=your-key kagi-mcp-server --help
• Check your client's logs for error messages
