Overview

AI-generated overview

Clack is a local MCP server for the Clack Mac app that lets an assistant capture, read, mark up and edit screenshots and recordings.

What you can do
Capture screenshots and screen recordings in Clack for Mac, as the description states it supports capture of both screenshots and recordings, though the manifest lists no individual tools. Read and inspect existing screenshots and recordings. Mark up and edit captured images and recordings. All actions run through the Clack app on the user's Mac.
When to use it
Useful when you work on a Mac with the Clack app and want an assistant to grab screenshots or recordings and annotate or edit them as part of a workflow, for example documenting steps or preparing visual material.
Requirements
Runs as a local process over stdio, distributed as an mcpb package, and is desktop only. Requires the Clack app for Mac to be installed. No authentication, environment variables or headers are declared.
Before you install
Screenshots and recordings can capture sensitive on-screen content, so consider what is visible before capturing. Marking up and editing changes the captured material, so review results before relying on them. The manifest lists no tools, so the exact scope of actions is unclear until installed.

Installation

In SourceWeft

  1. Open Clack in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
