Show HN: SharkClean MCP

This is nothing special but it has been very very nice to kick off cleaning jobs remotely via MCP. Working towards a genuinely smart home and this was a useful step in the right direction.

Show HN: Janus – MCP that collects context from browser and terminal

a_c — Fri, 12 Jun 2026 15:51:56 +0000

I'm finding myself more and more often typing what happened in my web app or terminal (or both) to prompt coding agent what to do. A string of interactions, clicked here, type that, some API calls, and console complaints, put that all mentally together and then prompts Claude.

I am making this tool to make interaction gathering easier. It records user interaction in browser, make a prompt that describes what happened, send the events to a local MCP server that Claude can access. A command line tool that streams terminal output, in my case, server log, to the same MCP so claude can access both what happened in browser and terminal as a stream of events.

The idea is to emphasize that ideas often come from product, in contrast to mainstream belief that idea leads to product. The end is the start. Hence the project name janus.

It is still very early in development so would love to hear some feedback.
