What changed
Watcher tags are now fully available over MCP. An agent can set tags at the moment it creates a Watcher, read them back, and re-tag later — so everything it builds arrives labelled.
Why it matters
More people set Prowlo up by telling an agent what to watch than by clicking through the dashboard. Anything the agent couldn't set simply never got done: a dozen Watchers with no labels, and no way to tell competitor tracking from community monitoring at a glance.
Tags also make alerting simpler. An alert on the tag competitor covers every competitor you track, and adding a new one needs no alert edit.
How to use it
Ask your agent to tag as it builds: "watch these five competitors, tag each one competitor plus its name". A convention that works well:
competitor+ the name for rivalsbrand+ your product for your own mentionscommunityfor audience subreddits
One caveat: tags apply from when they're set, so records already collected stay untagged. Tag at creation and it never comes up.
