webfetch

The license-first image layer for AI agents and humans.

One MCP server, one CLI, and one HTTP server that federate across 24 image providers, rank results license-first, and refuse to return anything you can't safely ship. Any agent that speaks MCP (Claude Code, Cursor, Cline, Continue, Roo Code, Codex) wires up from one config line. Landing page, pricing, and hosted usage live at getwebfetch.com.

Install

Surface	One-liner
npm	npm i -g @webfetch/cli
Homebrew	brew tap ashlrai/webfetch && brew install webfetch
Docker	docker run --rm ghcr.io/ashlrai/webfetch cli --help
curl | bash	curl -fsSL https://raw.githubusercontent.com/ashlrai/webfetch/main/install/install.sh | bash

The curl | bash installer also wires webfetch into Claude Code's ~/.claude/settings.json idempotently. Re-run any time to update.

30-second usage

CLI:

webfetch search "drake portrait" --limit 5
webfetch artist "Taylor Swift" --kind portrait --min-width 1200
webfetch download <url> --out ./portrait.jpg

MCP (from inside any MCP-speaking agent):

search_images({ query: "drake portrait", limit: 5 })
search_artist_images({ name: "Taylor Swift", kind: "portrait" })
download_image({ url: "..." })

TypeScript library:

import { searchArtistImages, pickBest, downloadImage } from "@webfetch/core";

const { candidates } = await searchArtistImages("Drake", "portrait");
const best = pickBest(candidates, { minWidth: 1200 });
if (best) {
  const { cachedPath, sha256 } = await downloadImage(best.url);
  console.log(best.attributionLine, "->", cachedPath);
}

What problem this solves

Manually sourcing an image has four failure modes:

1. You don't know the license, so you can't safely ship the result.
2. You can't script it — every new site means another afternoon.
3. Google's Image Search API is retired; scraping is brittle and ToS-grey.
4. No shared cache — you re-download the same file dozens of times.

webfetch fixes all four by federating across direct-source APIs that have stable terms and structured license metadata, ranking candidates license-first, and exposing the result as a single MCP tool.

Why license-first

The only outcome we refuse is shipping an image we can't justify. A marginally-better photo under an unknown license is worthless to a pipeline that needs to ship without human review. Relevance ties are easy to break; provenance is not.

The ranker sorts by: license tag -> metadata confidence -> resolution -> provider priority. UNKNOWN is rejected by default (Berne Convention: most of the web is all-rights-reserved unless proven otherwise). See docs/LICENSE_POLICY.md.

Every surface shares ~/.webfetch/cache/ keyed by SHA-256, so a download from the CLI is instantly available to the MCP server and vice versa.

Safety defaults

• licensePolicy: "safe-only" — UNKNOWN results rejected.
• safeSearch: "strict".
• Opt-in providers (youtube-thumb, bing, serpapi, browser, europeana-archival) off by default.
• 20 MB per-download cap, content-type guard, host blocklist.
• robots.txt respected on generic page probes.

Roadmap

• webfetch watch — daemon mode for repeated queries / incremental refresh.
• Bring-your-own-provider plugin API.
• Hosted tier at getwebfetch.com — pooled provider keys, managed browser fallback, team usage dashboard.
