Install Lookout in Claude Code, Cursor or VS Code

Runs npx -y @sylphx/lookout on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add lookout -- npx -y @sylphx/lookout
Add to Cursor

Lookout

Web research with source-level proof

Lookout gives agents a small, fast, local web product: search, fetch, extract, cache, crawl, and research with citeable excerpts.

npx -y @sylphx/lookout

For Claude Code:

claude mcp add lookout -- npx -y @sylphx/lookout

The fastest useful workflow

npx -y @sylphx/lookout search "Model Context Protocol"
npx -y @sylphx/lookout fetch https://example.com
npx -y @sylphx/lookout extract https://example.com

The MCP server exposes the same workflow to agents. Results include source URLs, excerpt spans, fetch routes, freshness signals, warnings, and gaps.

Jobs Lookout is built for

Tool surface

Predictable defaults

pages fail honestly.

  • fast uses local HTML search and fetch with no API key.
  • quality explicitly enables richer extraction and local cache expansion.
  • research is an explicit multi-step operation with page and budget limits.
  • Browser rendering and model synthesis are opt-in.
  • Private addresses, unsupported schemes, oversized responses, and blocked

Why agents trust it

Lookout returns excerpts pinned to source spans and labels stale cache, failed engines, redirects, blocked pages, and extraction gaps. It does not turn a challenge page or a thin response into a confident answer.

Companion MCP tools

Each product is independent. Install only the tools your agent needs.
