README

@litellm/agent-sdk

TypeScript client for [LiteLLM managed agents](https://github.com/BerriAI/litellm/pull/27427). Two primitives: `Agent`, `Session`. The runtime is a Fargate sandbox in **your** AWS — the SDK doesn't host anything.

import { Agent } from "@litellm/agent-sdk";

const agent = await Agent.create({
  // LAP — control plane
  apiKey: process.env.LITELLM_AGENT_PLATFORM_KEY!,
  baseUrl: process.env.LITELLM_AGENT_PLATFORM_URL!,
  model: "anthropic/claude-haiku-4-5",
  templateId: "tpl_opencode_my_repo",
  prompt: "You are a senior reviewer.",
});

const session = await agent.createSession({
  initialPrompt: "In one sentence, what is this repo about?",
});

const reply = await session.send("Now show me the routes file.");

for await (const ev of session.events()) console.log(ev.type, ev);

Install

npm i @litellm/agent-sdk

Node 20+. ESM only.

Two endpoints, two pairs of creds

The SDK touches two URLs. Keep them straight:

Role	SDK option	Who calls it
LiteLLM Agent Platform (LAP) — control plane	`apiKey` + `baseUrl` on `Agent.create`	the SDK (your process)
LiteLLM Gateway — LLM completions backend	`litellmApiKey` + `litellmApiBase` on `Agent.create` (optional)	the harness inside the spawned sandbox

The gateway pair is **forwarded** to the harness via the agent template. The SDK never calls the gateway directly. Leave the gateway pair unset to use LAP's server-side default.

const agent = await Agent.create({
  // LAP — what this SDK talks to
  apiKey: process.env.LITELLM_AGENT_PLATFORM_KEY!,
  baseUrl: process.env.LITELLM_AGENT_PLATFORM_URL!,
  // Gateway — optional override for the LLM backend the harness uses.
  // Forwarded onto the agent template; leave unset to inherit LAP's
  // server-side default.
  litellmApiKey: process.env.LITELLM_GATEWAY_KEY,
  litellmApiBase: process.env.LITELLM_GATEWAY_URL,
  model: "anthropic/claude-haiku-4-5",
  templateId: "tpl_openco
