Building on top of AI context infrastructure requires reverse-engineering internal protocols.
The LeanCTX SDK provides a typed TypeScript client for the full Context OS API. Call any tool, subscribe to events, mutate sessions, and query knowledge — all through a clean, documented interface. The same API is available as REST endpoints for any language.
No Public Interface
You want to build a dashboard, a CI integration, or a custom agent orchestrator. But the only interface is an internal MCP protocol designed for IDE consumption, not programmatic access.
Connect to the Context OS and subscribe to workspace events with just a few lines of TypeScript.

REST API
Every tool and endpoint available as REST. JSON request/response with typed errors and rate limiting.
Token Authentication
Team tokens with configurable scopes. SHA-256 hashed, config-driven issuance via lean-ctx team token create.

すべての出力に証拠が付随
LeanCTXはすべてのセッションの証拠アーティファクトを生成します：どのファイルが読み取られたか、何が圧縮されたか、どのチェックが通過したか、トークンがどのように使用されたか。これによりAI作業は監査可能、再現可能、信頼に値するものになります。
