URL Blocking

The fetch_page tool blocks requests to private/internal networks by default (SSRF protection). To allow specific internal hosts:

export SF_FETCH_ALLOWED_URLS="internal-docs.company.com,192.168.1.50"

Or set fetchAllowedUrls in ~/.sf/agent/settings.json.

Blocked by default: private IP ranges, cloud metadata endpoints, localhost, non-HTTP protocols, IPv6 private ranges.
