Janus MCP pipes browser and terminal context to Claude automatically
Janus is an early-stage MCP tool that records browser interactions and streams terminal output to a local MCP server, giving Claude direct access to both sources of context without manual copy-pasting.
Score breakdown
Janus removes the manual step of narrating browser and terminal activity to a coding agent by piping that context directly into Claude via a local MCP server.
- 01Records browser user interactions and converts them into a prompt describing what happened
- 02Sends browser events to a local MCP server that Claude can access
- 03A CLI tool streams terminal output (e.g., server logs) to the same MCP server
The author, posting under the handle `a_c`, describes a recurring pain point: manually reconstructing a sequence of browser interactions, API calls, and console errors into a coherent prompt for a coding agent. Janus is their solution — a tool that automates context collection by recording browser interactions, converting them into a descriptive prompt, and forwarding the events to a local MCP server accessible by Claude.
The result is a combined, real-time stream of browser and terminal events that Claude can query directly, removing the need for the developer to mentally aggregate and retype what happened.
A companion command-line tool complements the browser recorder by streaming terminal output (such as server logs) to the same MCP server. The result is a combined, real-time stream of browser and terminal events that Claude can query directly, removing the need for the developer to mentally aggregate and retype what happened.
The project is described as very early in development. The name "Janus" reflects the author's philosophical framing: that ideas often emerge from observing a product in action, rather than preceding it — "the end is the start."
