ketch-cli

Fast, stateless CLI for web search, OSS code search, library docs, scraping, and crawling — with an MCP server for agents.

This is the npm distribution of ketch. The package is ketch-cli; the command it installs is ketch.

Full documentation: ketch.run

Use it without installing

npx -y ketch-cli search "golang error handling"
npx -y ketch-cli scrape https://go.dev/doc/effective_go

As an MCP server

ketch mcp serve exposes six tools — search, code, docs, scrape, crawl, and tag — over stdio. To register it with Claude Code:

claude mcp add ketch -- npx -y ketch-cli mcp serve

Or in an MCP client's config file:

{
  "mcpServers": {
    "ketch": {
      "command": "npx",
      "args": ["-y", "ketch-cli", "mcp", "serve"]
    }
  }
}

The binary ships in a per-platform package selected through optionalDependencies, so nothing is downloaded during install and no postinstall script runs. That keeps startup fast when a client relaunches the server, and it works in environments that set --ignore-scripts.

Install it properly

npm install -g ketch-cli   # then: ketch search "query"

Other install routes — Homebrew, go install, or a checksum-verified shell installer — are covered at ketch.run.

Supported platforms

macOS, Linux, and Windows on x64 and arm64. On anything else, build from source:

go install github.com/1broseidon/ketch@latest
