scrapbox-cosense-mcp-editable

日本語ドキュメント / Japanese

Overview

MCP server for Cosense (formerly Scrapbox). Fork of worldnine/scrapbox-cosense-mcp that adds page-deletion and line-editing tools (delete_page, edit_lines).

Tool	Description	Auth Required
get_page	Get page content, metadata, and links	For private projects
list_pages	Browse pages with sorting and pagination (max 1000)	For private projects
search_pages	Full-text search with keyword highlighting (max 100 results)	For private projects
create_page	Create a page via WebSocket API with Markdown/Scrapbox body	Yes
get_page_url	Generate direct URL for a page	No
insert_lines	Insert text after a specified line in a page	Yes
edit_lines	Replace an exact-match line (one or all occurrences) with new content	Yes
delete_page	Delete a page by emptying every line via WebSocket patch	Yes
get_smart_context	Get a page and its linked pages (1-hop/2-hop) in AI-optimized format	Yes

create_page, insert_lines, and edit_lines support a format parameter ("markdown" or "scrapbox") to control content conversion.

Note on delete_page: Cosense automatically removes a page once all of its lines are empty. This tool sends a WebSocket patch that returns an empty line array — there is no "undo".

Quick Start

Desktop Extension (.mcpb) — Easiest

1. Download scrapbox-cosense-mcp-editable.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 qurihara/scrapbox-cosense-mcp-editable
   

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
