Size-efficient URL fetch with semantic extraction. Use for ad-hoc web research when you want content without the raw HTML overhead.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# /fetch -- Ad-hoc URL fetch with smart extraction

Pulls a URL's main content (title, description, body paragraphs) without the HTML boilerplate. Delegates to Grainulator’s `memory_smart_fetch` MCP tool, which strips scripts/styles/nav/footer and targets `<main>` or `<article>` regions. Typical reduction: 80-99% vs raw HTML.

## Arguments

$ARGUMENTS

Expected: `/fetch <url> [--mode auto|concise|full|meta-only] [--no-cache] [--privacy]`

- **`--mode auto`** (default): tries concise extraction; retries full only when extraction failed and was truncated
- **`--mode concise`**: caps body at ~2KB
- **`--mode full`**: returns fuller extraction within fetch/body limits; check truncation
- **`--mode meta-only`**: only title + description (smallest)
- **`--no-cache`**: skip local cache read, force network fetch
- **`--privacy`**: don't write to cache (use for sensitive URLs)

## When to use

- **Quick reference**: "what does this page say" — `/fetch <url>` beats opening a browser
- **Before witnessing**: peek at content before committing to `/witness` (which creates a claim)
- **Third-party pages**: docs sites, blog posts, research articles

How to install

The exact contents, by fingerprint

mdr add grainulation/grainulator/fetch@sha256:4d7d18874130fd0c

The line at the top of this page pins the label git:20260922.e702f49, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
