Build an AI Brand Monitoring Agent

Brand monitoring is the practice of tracking what people say about your product, company, or competitors across the web. Done well, it surfaces complaints before they snowball, catches positive testimonials you can share with the team, and flags when a competitor lands a big press mention. Done poorly, it’s a tab you open once a week, skim, and close.

Why it’s hard

Mentions don’t live in one place. A frustrated user posts on Reddit today. Someone mentions your product in a Hacker News thread tomorrow. A tech journalist writes a comparison piece next week. Watching all of that requires checking multiple sources on some kind of schedule, which is a great way to forget to do it entirely.

Traditional tools exist for this. Brandwatch, Mention, Sprout Social. They aggregate mentions into dashboards, send digests, and let you filter by sentiment. The tradeoff: they’re priced for enterprise marketing teams, not a two-person startup. And even with the nicest dashboard, someone still has to read it and decide what matters.

The core problem isn’t access to data. It’s that turning raw mentions into useful signals takes time, and time is the thing nobody has.

What an agent changes

An AI agent can handle the whole pipeline: fetch mentions, read them, summarize what matters, and send you a short email. No dashboard to log into. No tab to remember.

The workflow looks like this:

  1. Search Reddit for your brand name and product name
  2. Search Hacker News for the same terms
  3. Check Google News for press coverage
  4. Read through the results and write a short summary: how many mentions, what’s the general tone, anything that needs a response
  5. Send that summary as an email digest

You can run this daily, weekly, or on demand. The agent handles the boring part (fetching and reading) so you only spend time on the part that requires judgment (deciding what to do about it).

The summary step is where agents earn their keep. Instead of a list of 40 links, you get a paragraph: “3 new Reddit threads this week. Two users asking about pricing, one complaint about the onboarding flow. One Hacker News comment in a thread about competitor X, positive. No significant press coverage.” That takes 10 seconds to read.

Building it with AgentPatch

AgentPatch gives your AI agent access to Reddit, Hacker News, Google News, email, and 50+ other tools through a single MCP connection. No separate API keys for each service, no OAuth flows to wire up.

The tools you need for brand monitoring:

  • reddit-search: searches Reddit posts and comments (300 credits per call)
  • hackernews-search: searches Hacker News stories and comments (50 credits per call)
  • google-news: fetches recent Google News results for a query (75 credits per call)
  • send-email: sends an email with the digest output

At AgentPatch’s pricing (10,000 credits = $1.00), a daily brand monitoring run costs under a cent. You can monitor aggressively without worrying about the bill.

The agent prompt is the core of the workflow. Something like: “Search Reddit, Hacker News, and Google News for mentions of [brand name]. For each source, note how many results you found and summarize the sentiment. Flag anything that looks like a complaint or a PR opportunity. Then send an email to [address] with a short digest.”

That’s it. The agent calls the tools, reads the results, writes the summary, and sends the email. You get a message in your inbox.

Setup

Connect AgentPatch to your AI agent to get access to the tools:

Wrapping Up

An AI brand monitoring agent turns a task that requires constant attention into something that runs in the background and emails you when it finds something worth reading. The tools to do this are available now, and the cost is negligible.

If you want to build one, agentpatch.ai has everything you need in one place.
