Retrieve clean markdown from URLs when web_fetch fails. Converts pages via Jina AI reader service with automatic retry. Use when web_fetch or curl returns 403, blocked, paywall, timeout, JavaScript-rendering errors, or empty content or user explicitly suggests using jina.
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
# Fetching Blocked URLs
Retrieve readable content from URLs that web_fetch cannot access. Jina AI's reader service renders JavaScript, bypasses soft blocks, and returns clean markdown.
## Activation Triggers
Invoke this skill immediately when web_fetch returns:
- 403 Forbidden or access denied
- Paywall or login wall indicators
- Empty, garbled, or truncated content
- JavaScript-heavy SPA failures
- Timeout errors
## Core Command
```bash
curl -s --max-time 30 "https://r.jina.ai/TARGET_URL"
```
The service returns markdown with page title, body text, and preserved links.
## Retry Pattern
Jina's backend has ~10% intermittent failures. Use retry logic to achieve 99%+ success:
```bash
for attempt in 1 2 3; do
result=$(curl -s --max-time 30 "https://r.jina.ai/TARGET_URL" 2>&1)
echo "$result" | grep -q "upstream connect error" || { echo "$result"; break; }
[ $attempt -lt 3 ] && sleep 1
done
```
## Workflow Integration
1. **Primary**: Use web_fetch (native tool)
2. **Fallback**: This skill with retry when web_fetch fails
3. **Escalate**: Request user assistance only after retry exhaustion
Attempt this fallback before asking users to copy-paste content manually.

How to install
mdr add oaustegard/claude-skills/fetching-blocked-urls@sha256:5ac330ff442bfc61The line at the top of this page pins the label v0.1.1, 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.
