@huggingface/tiny-agents

A squad of lightweight composable AI applications built on Hugging Face's Inference Client and MCP stack.

Installation

npm install @huggingface/tiny-agents
# or
pnpm add @huggingface/tiny-agents

CLI Usage

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:

mkdir my-agent
touch my-agent/agent.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:

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

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);
        }
    }
}
