+# @huggingface/tiny-agents
+
+![meme](https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/blog/tiny-agents/legos.png)
+
+A squad of lightweight composable AI applications built on Hugging Face's Inference Client and MCP stack.
+
+## Installation
+
+```bash
+npm install @huggingface/tiny-agents
+# or
+pnpm add @huggingface/tiny-agents
+```
+
+## CLI Usage
+
+```bash
+npx @huggingface/tiny-agents [command] "agent/id"
+
+```
+
+```
+Usage:
+  tiny-agents [flags]
+  tiny-agents run   "agent/id"
+  tiny-agents serve "agent/id"
+
+Available Commands:
+  run         Run the Agent in command-line
+  serve       Run the Agent as an OpenAI-compatible HTTP server
+```
+
+## Define your own agent
+
+The simplest way to create your own agent is to create a folder containing an `agent.json` file:
+
+```bash
+mkdir my-agent
+touch my-agent/agent.json
+```
+
+```json
+{
+	"model": "Qwen/Qwen2.5-72B-Instruct", // model id
+	"provider": "nebius", // or you can also use a local endpoint base url with `endpointUrl`
+	"servers": [
+		{
+			"type": "stdio",
+			"config": {
+				"command": "npx",
+				"args": ["@playwright/mcp@latest"]
+			}
+		}
+	]
+}
+```
+
+Where `servers` is a list of MCP servers (we support Stdio, SSE, and HTTP servers).
+
+Optionally, you can add a `PROMPT.md` file to override the default Agent prompt.
+
+Then just point tiny-agents to your local folder:
+
+```bash
+npx @huggingface/tiny-agents run ./my-agent
+```
+
+Voilà! 🔥
+
+> [!NOTE]
+> Note: you can open a PR in the huggingface.js repo to share your agent with the community, just upload it inside the `src/agents/` directory.
+
+### Advanced: Programmatic Usage
+
+```typescript
+import { Agent } from '@huggingface/tiny-agents';
+
+const HF_TOKEN = "hf_...";
+
+// Create an Agent
+const agent = new Agent({
+  provider: "auto",
+  model: "Qwen/Qwen2.5-72B-Instruct",
+  apiKey: HF_TOKEN,
+  servers: [
+    {
+      // Playwright MCP
+      command: "npx",
+      args: ["@playwright/mcp@latest"],
+    },
+  ],
+});
+
+await agent.loadTools();
+
+// Use the Agent
+for await (const chunk of agent.run("What are the top 5 trending models on Hugging Face?")) {
+    if ("choices" in chunk) {
+        const delta = chunk.choices[0]?.delta;
+        if (delta.content) {
+            console.log(delta.content);
+        }
+    }
+}
+```
