SDK & API

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.

typescript
typescript ()
- import { LeanCtx } from "@anthropic/lean-ctx-sdk";
-
- const ctx = new LeanCtx({
- baseUrl: "http://localhost:7700",
- workspace: "my-team",
- });
-
- for await (const ev of ctx.subscribe("feat/auth")) {
- console.log(ev.type, ev.data);
- }

Cada salida lleva prueba

LeanCTX genera artefactos de prueba para cada sesión: qué archivos se leyeron, qué se comprimió, qué verificaciones pasaron y cómo se gastaron los tokens. Esto hace que el trabajo de IA sea auditable, reproducible y confiable.
