Hi builders,
Our plugin BeachFinder was approved and published this week. Sharing what it does plus a few notes from the build, in case they help others shipping MCP-backed plugins.
What it does
Ask ChatGPT things like:
- “Warmest beach near Valencia right now?”
- “Compare three beaches near Miami for warm water, wind, UV and family suitability.”
- “Calm snorkeling spots near Split this week?”
It answers from live data: 184,900 real swim spots worldwide (beaches, lakes, bathing places) with current sea temperature, waves, wind, UV and community reports. Everything is read-only, and the plugin never declares a spot “safe to swim” - it defers to flags, lifeguards and local authorities.

Build notes
- It is backed by a remote MCP server (https://getbeachfinder.com/mcp - no auth, 12 read-only tools). The same server works from Claude, Cursor or any MCP client, so one backend covers every assistant surface.
- Keeping every tool read-only and putting explicit safety framing in the tool descriptions made review straightforward.
- The example prompts on the listing map 1:1 to the strongest tool use cases - worth spending time on them.
Happy to answer questions about the MCP setup or the review process. Feedback on the plugin itself is very welcome - solo developer here, I will take all of it.
