Inline review comments for markdown specs. Built-in MCP server hands feedback directly to your AI agent.
Md Redline MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. Inline review comments for markdown specs. Built-in MCP server hands feedback directly to your AI agent.
Once Md Redline is connected, these are the calls the assistant has available:
Two — way agent review over MCP: agents request your review, review your docs, and ask anchored questionsHand — off prompt copying for one or multiple filesMulti — tab editing with session persistence and tab context menusReal — time reload via SSE when files change externallymacOS — supportedLinux — supported; system file picker requires zenityWindows — supported; system file picker uses PowerShellVariable — DefaultMD_REDLINE_BROWSER — OS default browserMD_REDLINE_VITE_PORT — 5188MD_REDLINE_HOME — your OS home directoryMD_REDLINE_REGISTRY_URL — public npm registryYou will need one environment variable: MD_REDLINE_REGISTRY_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
md-redline on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Among the browser automation options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Md Redline's toolset — Two, Hand, Multi and 11 more — is a fair guide to whether it matches your workflow. It is maintained by dejuknow; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
