Background Fetching

Nothing in the server crawls on its own. list_entries_tool and friends read a cache; if no one calls --fetch, that cache goes stale and every reader sees an empty feed with no error anywhere. A deployment without a crawl trigger is a broken deployment — this bit the daily briefing, which reported "no news" for days while all 61 feeds sat unfetched.

# Fetch all feeds via CLImcp-feed-reader-crunchtools --fetch

systemd timer (recommended)

deploy/ ships the two units used in production. Copy them to /etc/systemd/system/, adjust the container name in the service if yours differs, then:

sudo systemctl daemon-reloadsudo systemctl enable --now mcp-feeds-refresh.timer

The service runs --fetch inside the running container (podman exec), so the database keeps the SELinux category of the process that owns it. Do not bind-mount the data directory into a second container with :Z to run the crawl — that relabels the volume and locks the live server out.

The timer fires hourly, plus once at 05:45. That second entry is not redundant: consumers window entries on publication time, so an entry published between the last crawl and a 06:00 report is missing from that report and already older than the next day's window start — it is lost for good. Any consumer on a fixed schedule wants a crawl shortly before it.

Feeds are fetched conditionally (ETag / If-Modified-Since). A rate limit, gateway 5xx, or dropped connection is retried with exponential backoff, up to three attempts in all, before the feed is recorded as failed.
