A social-listening agent that stays on the public side
Start with a keyword or community monitor that writes to Slack, Discord or Sheets. Add an MCP source when the agent should search on demand. Keep the platform object ID and the collection time, and do not mix public posts with private profile data.
Social listening is a set of source-specific jobs, not one feed. Reddit threads, Instagram comments, TikTok hashtags and LinkedIn company posts have different objects and access rules. The file set keeps the source explicit.
Method
Pick the platform and the object: a post, comment, hashtag, community or company page.
Choose a destination that fits the team: Slack or Discord for alerts, Sheets for a review queue.
Set a keyword and a time window. Log the platform object ID and the collection date.
Check the source page for access limits before increasing frequency or scope.

Skills for this job
Guardrails
- Public posts are still subject to platform terms, copyright and privacy rules.
- A social post is not a representative survey of a customer base.
- Do not bypass logins, private groups or protected accounts.
Questions
Can one agent monitor every social platform?
It can route across multiple sources, but each source has its own Actor, access route and object model. Keep the source-specific workflows separate so a change on one platform does not break every monitor.
Does the Reddit recipe still work after the API changes?
The Reddit target page and the API pricing page track the dated access changes. Check them before building, and use the route that is still available at the time you run the workflow.
Should I store the full post text?
Store the minimum needed for the task and keep the source URL and collection time. Copyright and platform terms still apply to public posts.
