Yocoolab MCP Server

MCP (Model Context Protocol) server that exposes Yocoolab feedback threads, design selections, and activity events as tools for Claude Code and other MCP-compatible clients. It runs locally over stdio via the published package.

People who work with code review, developer tools and visual feedback and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

Claude Code

claude mcp add yocoolab-mcp-server -- npx -y @yocoolab/mcp-server

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "yocoolab-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "@yocoolab/mcp-server"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
