scrapbox-mcp MCP サーバー

モデルコンテキストプロトコルサーバー

これは、シンプルなメモシステムを実装したTypeScriptベースのMCPサーバーです。以下の機能を提供することで、MCPのコアコンセプトを実証しています。

  • URIとメタデータを含むテキストメモを表すリソース

  • 新しいノートを作成するためのツール

  • メモの要約を生成するためのプロンプト

特徴

リソース

  • note:// URI 経由でメモの一覧表示とアクセスを行う

  • 各ノートにはタイトル、内容、メタデータがあります

  • シンプルなコンテンツアクセスのためのプレーンテキスト MIME タイプ

ツール

  • create_note - 新しいテキストノートを作成する

    • タイトルとコンテンツを必須パラメータとして受け取ります

    • メモをサーバー状態に保存する

プロンプト

  • summarize_notes - 保存されているすべてのメモの要約を生成する

    • すべてのノートの内容を埋め込みリソースとして含めます

    • LLM要約のための構造化されたプロンプトを返す

発達

依存関係をインストールします:

npm install

サーバーを構築します。

npm run build

自動リビルドを使用した開発の場合:

npm run watch

インストール

Claude Desktop で使用するには、サーバー設定を追加します。

MacOS の場合: ~/Library/Application Support/Claude/claude_desktop_config.json Windows の場合: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "scrapbox-mcp": {
      "command": "/path/to/scrapbox-mcp/build/index.js"
    }
  }
}

デバッグ

MCPサーバーはstdio経由で通信するため、デバッグが困難になる場合があります。パッケージスクリプトとして提供されているMCP Inspectorの使用をお勧めします。

npm run inspector

インスペクターは、ブラウザでデバッグ ツールにアクセスするための URL を提供します。

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It states the tool fetches content but lacks details on behavioral traits such as error handling (e.g., invalid URLs, authentication needs), rate limits, or what 'content' entails (e.g., raw HTML, parsed text). This leaves significant gaps for an agent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence with zero waste—it directly states the tool's function without unnecessary words. It is appropriately sized and front-loaded, making it easy to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's low complexity (1 parameter, no output schema, no annotations), the description is minimally complete. It covers the basic purpose but lacks details on behavior and output, which are needed for full contextual understanding. It's adequate but has clear gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with the parameter 'url' fully documented in the schema. The description adds no additional meaning beyond implying it's for Scrapbox pages, which the schema example already suggests. Baseline 3 is appropriate as the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Fetch content') and target resource ('from a Scrapbox page by URL'), making the purpose immediately understandable. It doesn't need to differentiate from siblings since none exist, but it could be more specific about what 'content' includes (e.g., text, metadata, structure).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage when needing page content from a Scrapbox URL, but provides no explicit guidance on when to use this tool versus alternatives (e.g., other fetching methods) or any prerequisites. With no sibling tools, the baseline is adequate but unguided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Disambiguation5/5

With only one tool, there is no possibility of confusion or overlap between tools, making disambiguation perfect. The tool's purpose is clearly defined and distinct by default.

Naming Consistency5/5

The single tool follows a clear verb_noun pattern (get_page_content), and with no other tools to compare, consistency is inherently perfect. There are no deviations or mixed conventions.

Tool Count2/5

One tool is too few for a server named 'Scrapbox MCP Server', which implies broader functionality for interacting with Scrapbox pages. A single fetch tool feels thin and limited in scope, suggesting an incomplete or minimal implementation.

Completeness2/5

The tool surface is severely incomplete for a Scrapbox server, covering only fetching page content. Obvious gaps include creating, updating, deleting, or listing pages, which are essential operations for managing a wiki or note-taking system like Scrapbox.
