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.

Chaque sortie porte une preuve
LeanCTX génère des artefacts de preuve pour chaque session : quels fichiers ont été lus, ce qui a été compressé, quelles vérifications ont réussi et comment les tokens ont été dépensés. Cela rend le travail IA auditable, reproductible et fiable.
