Quick Start

Desktop Extension (.mcpb) — Easiest

1. Download scrapbox-cosense-mcp.mcpb from GitHub Releases
2. Double-click — Claude Desktop opens an install dialog
3. Enter your project name (and Session ID for private projects)

Claude Code Plugin

1. Add the marketplace:

   /plugin marketplace add worldnine/scrapbox-cosense-mcp
   

2. Install the plugin:

   /plugin install scrapbox-cosense@worldnine-scrapbox-cosense-mcp
   

   Installs globally by default. Use --scope project or --scope local for other scopes.
3. Set environment variables in your settings file:

   {
     "env": {
       "COSENSE_PROJECT_NAME": "your_project_name",
       "COSENSE_SID": "your_sid"
     }
   }
   

   File	Scope
   ~/.claude/settings.json	All projects (global)
   .claude/settings.local.json	This project only (gitignored)

The plugin includes MCP server configuration and a /cosense skill for CLI operations.

Claude Code (Manual MCP Setup)

If you prefer manual configuration over the plugin:

claude mcp add scrapbox-cosense-mcp \
  -e COSENSE_PROJECT_NAME=your_project \
  -e COSENSE_SID=your_sid \
  -- npx -y scrapbox-cosense-mcp
