The hardest part of publishing consistently is not writing — it is deciding what to write about. Link2Threads' MCP server includes a keyword_search tool that searches Threads posts by keyword, so you can look at what is already being posted and read on your topic before you commit to an angle.
What keyword_search does
Give it a keyword and it returns Threads posts matching that keyword. It runs through your connected agent (see the MCP getting-started guide), and it has a daily quota — when the quota is used up, calls return a KEYWORD_QUOTA (429) error until the next day. One honest caveat: keyword search depends on a Threads search permission, and if that scope is not approved for your connection, the search can fail. If it does, the rest of this workflow still works with manual browsing — the search is an accelerator, not the foundation.
A 15-minute research routine
- Start with three seed keywords. One for your product or niche, one for the problem your readers have, one for the format ("how to", a comparison, a mistake). Vague single words return noise; two-to-three-word phrases return topics.
- Read for patterns, not posts to copy. Note which hooks repeat: questions, concrete numbers, before/after, myth-busting. Note which posts ask something — question posts tell you exactly what readers want explained.
- Pick one angle you can source. A search result is inspiration, not material. Your thread still needs a real source URL behind it. Find the article, page, or data that supports the angle, then generate cards from that URL.
- Check it against your own history. Ask the agent for your top posts (
get_top_posts) on nearby topics. A keyword that is busy platform-wide but has never worked on your account is a weaker bet than one your own audience already answered.
Spend the daily quota like it matters
Because searches are capped per day, batch them: write down the week's candidate keywords first, run them in one session, and save the results where you plan content. Five planned searches teach you more than twenty scattered ones, and you will still have quota left when a timely topic appears.
What this is not
Keyword search shows you what exists; it does not predict what will go viral, and copying a winning post's wording rarely survives contact with your own audience. Use it the way our census posts use data — as a way to choose the next experiment on evidence instead of vibes. The routine in How to Keep Publishing on Threads Without Posting Every Day pairs well with this: search decides what, the routine decides when.
