gemini-mcp-server

直接 API 呼び出しを使用して Google の Gemini モデルと統合する Model Context Protocol (MCP) サーバーの TypeScript 実装。

特徴

  • Gemini API への直接呼び出しを使用します (非推奨の SDK はありません)

  • 最新のGemini 2.0 Flashモデルをサポート

  • Claudeとのシームレスな統合のためにMCPプロトコルを実装

  • 自然なやりとりのために会話の文脈を維持する

MCPツール

テキストを生成する

サーバーから: gemini

設定可能なパラメータを持つ Gemini モデルを使用してテキストを生成します。

前提条件

  • Node.js 18以上

  • Google Gemini APIキー

  • タイプスクリプト

  • クロードデスクトップアプリ

インストール

  1. リポジトリをクローンします。

git clone https://github.com/YOUR-USERNAME/gemini-mcp-server.git
cd gemini-mcp-server
  1. 依存関係をインストールします:

npm install
  1. 建てる:

npm run build

クロードデスクトップ統合

このサーバーをClaude Desktopで使用するには:

  1. クロードデスクトップを開く

  2. 設定 > 開発者

  3. 「設定を編集」をクリック

  4. 次の構成を追加します。

"gemini": {
  "command": "node",
  "args": ["path\\to\\dist\\gemini_mcp_server.js"],
  "env": {
    "GEMINI_API_KEY": "gemini_api_key"
  },
  "cwd": "path\\to\\gemini-mcp-server"
}

交換する:

  • /path/to/gemini-mcp-serverリポジトリへの絶対パスで指定します。

  • your_api_key_hereに実際の Google Gemini API キーを入力します

これで、サーバーは Claude Desktop の MCP サーバー リストで利用できるようになります。

API実装

このサーバーは、Gemini APIエンドポイントへの直接HTTPリクエストを使用します。APIリクエストの形式はGoogleの公式ドキュメントに準拠しています。

curl "https://generativelanguage.googleapis.com/v1beta/models/gemini-2.0-flash:generateContent?key=GEMINI_API_KEY" \
-H 'Content-Type: application/json' \
-X POST \
-d '{
  "contents": [{
    "parts":[{"text": "Explain how AI works"}]
    }]
   }'

テスト

サンプル スクリプトを使用して直接 API 実装をテストできます。

node dist/example_direct_api.js "Your prompt here"

TDQS

D1/5.0
Behavior1/5

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

Tool has no description.

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

Conciseness1/5

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

Tool has no description.

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

Completeness1/5

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

Tool has no description.

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

Parameters1/5

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

Tool has no description.

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

Purpose1/5

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

Tool has no description.

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

Usage Guidelines1/5

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

Tool has no description.

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

D1.7/5.0

Disambiguation5/5

With only one tool, there is no possibility of ambiguity or overlap between tools. The single tool 'generate_text' has a distinct purpose by default.

Naming Consistency5/5

A single tool inherently has perfect naming consistency, as there are no other tools to compare it against. The name 'generate_text' follows a clear verb_noun pattern.

Tool Count2/5

One tool is too few for a server named 'Gemini MCP Server', which suggests a broader scope like interacting with Gemini AI services. A single text generation tool feels thin and incomplete for such a domain.

Completeness1/5

The server is severely incomplete for its implied purpose. With only a text generation tool, it lacks essential operations like chat interactions, model selection, or other AI functionalities expected from a Gemini server, leading to significant gaps.
