Windows のローカル ambient context (在席状態、フォアグラウンドアプリ種別、バッテリ、電源イベント、システム負荷、長時間作業の検知など) を、プライバシー分類された MCP ツールとして任意の AI クライアント (Claude Code、Claude Desktop 等)
Most developer tooling work still happens through a UI a human drives. Ambient Context MCP MCP server moves it into the conversation instead. Windows のローカル ambient context (在席状態、フォアグラウンドアプリ種別、バッテリ、電源イベント、システム負荷、長時間作業の検知など) を、プライバシー分類された MCP ツールとして任意の AI クライアント (Claude Code、Claude Desktop 等) に公開するトレイ常駐プロセスです。.
The server ships on npm as @anthropic-ai/mcpb, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
The server publishes 4 tools. What each one is for:
ambient_context_get_states — 現在のコンテキスト状態 (presence, battery, フォアグラウンドアプリ種別 等)ambient_context_poll_events — クライアント別カーソル以降の未読イベント (user_returned, ac_power_connected 等)ambient_context_describe_events — 全イベントの payload スキーマカタログ (sensitivity / 説明 / 例値、実データは含まない)ambient_context_get_policy — 機微度分類と有効送信可否の診断情報 (実データは含まない)This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Ambient Context MCP's toolset — ambient_context_get_states, ambient_context_poll_events, ambient_context_describe_events and 1 more — is a fair guide to whether it matches your workflow. It is maintained by nassie256; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
