local-context-mcp
A local Model Context Protocol server designed to share contextual information between an AI and a user. It primarily provides a tool to retrieve the current date and time in ISO 8601 format based on the server's local timezone.
README
local-context-mcp
local-context-mcp は、MCP サーバ実装の習作として作ったミニプロジェクトです。
AIとユーザが同じ環境にいる前提で、現在の文脈を共有するために便利、かもしれない、機能を提供します。
機能説明
- ローカルで動く MCP サーバ
- AIとユーザが同じ場所にある前提で、現在日時を共有するための tool を提供
when-is-now
- 現在日時(ISO 8601形式)を返します
- タイムゾーンはサーバ実行環境のローカルタイムゾーンに従う
- 詳細は
docs/tools/when-is-now.mdを参照
開発者向け
詳細は package.json や AGENTS.md を参照。 以下は一般向け機能ではなく、開発やテストのための tools
dev-helloworld
- メッセージ
hello worldを返すだけ
dev-error-test
- 結合テスト用の tool
- MCP の tool error result を返す挙動を確認
- 詳細は
docs/tools/dev-error-test.mdを参照
LM Studio から Docker で使う
詳細仕様は docs/docker.md を参照。
事前準備
- Docker イメージをビルドする
npm run docker:build
設定例
- LM Studio の MCP サーバ設定に以下を追加する
when-is-nowはサーバ実行環境のローカルタイムゾーンを返すため、TZは明示する

"mcpServers": {
"local-context": {
"command": "docker",
"args": [
"run",
