I use Coding tools daily and got tired of it describing code by line numbers. So I built an MCP server that lets the agent control my Neovim instance instead: opening files, highlighting lines, adding annotations, splitting views.

The tool I actually wanted was "walkthrough mode": I ask the agent to walk me through a PR, it opens each file, highlights what matters, explains briefly, and waits for my questions. Turns code review into pair programming where the agent points at the screen.

It also works passively — while the agent investigates a bug or reads code, my Neovim follows along so I can see what it's looking at.

Built with pynvim, talks to Neovim via --listen socket. Works with any MCP client.
