一个由 Starknet 驱动的代理引擎,用于创建强大且安全的 AI 代理。它既可以作为 NPM 包使用,也可以作为即用型后端使用。
快速入门
先决条件
- Starknet 钱包(推荐: Argent X )
- AI 提供商 API 密钥(Anthropic/OpenAI/Google Gemini/Ollama)
- 已安装 Node.js 和 pnpm
安装
git clone https://github.com/kasarlabs/snak.git
cd snak
pnpm install
配置
- 通过复制
.env.example
创建.env
文件:
然后,在.env
文件中填写必要的值:
# --- Starknet configuration (mandatory) ---
STARKNET_PUBLIC_ADDRESS="YOUR_STARKNET_PUBLIC_ADDRESS"
STARKNET_PRIVATE_KEY="YOUR_STARKNET_PRIVATE_KEY"
STARKNET_RPC_URL="YOUR_STARKNET_RPC_URL"
# --- AI Model API Keys (mandatory) ---
# Add the API keys for the specific AI providers you use in config/models/default.models.json
# The agent will automatically load the correct key based on the provider name.
# Example for OpenAI:
OPENAI_API_KEY="YOUR_OPENAI_API_KEY" # (e.g., sk-...)
# Example for Anthropic:
ANTHROPIC_API_KEY="YOUR_ANTHROPIC_API_KEY" # (e.g., sk-ant-...)
# Example for Google Gemini:
GEMINI_API_KEY="YOUR_GEMINI_API_KEY"
# Example for DeepSeek:
DEEPSEEK_API_KEY="YOUR_DEEPSEEK_API_KEY"
# Note: You do not need an API key if using a local Ollama model.
# --- General Agent Configuration (mandatory) ---
SERVER_API_KEY="YOUR_SERVER_API_KEY" # A secret key for your agent server API
SERVER_PORT="3001"
# --- PostgreSQL Database Configuration (mandatory) ---
POSTGRES_USER="admin"
POSTGRES_PASSWORD="admin"
POSTGRES_ROOT_DB="postgres" # Database used to create/manage the application database
POSTGRES_HOST="localhost"
POSTGRES_PORT="5454"
# --- LangSmith Tracing (Optional) ---
# Set LANGSMITH_TRACING=true to enable tracing
LANGSMITH_TRACING=false
LANGSMITH_ENDPOINT="https://api.smith.langchain.com"
LANGSMITH_API_KEY="YOUR_LANGSMITH_API_KEY" # (Only needed if LANGSMITH_TRACING=true)
LANGSMITH_PROJECT="Snak" # (Optional project name for LangSmith)
# --- Node Environment ---
NODE_ENV="development" # "development" or "production"
- 配置 AI 模型(可选):
config/models/default.models.json
文件定义了用于不同任务( fast
、 smart
、 cheap
)的默认 AI 模型。您可以自定义此文件,或创建新的模型配置(例如my_models.json
),并在运行代理时指定它们。请参阅config/models/example.models.json
了解其结构。代理使用模型配置中的provider
程序字段来确定从.env
文件加载哪个 API 密钥(例如,如果provider
是openai
,它会加载OPENAI_API_KEY
)。 - 在
config/agents/
目录中创建代理配置文件(例如default.agent.json
或my_agent.json
):
{
"name": "Your Agent name",
"group": "Your Agent group",
"description": "Your AI Agent Description",
"lore": ["Some lore of your AI Agent 1", "Some lore of your AI Agent 1"],
"objectives": [
"first objective that your AI Agent need to follow",
"second objective that your AI Agent need to follow"
],
"knowledge": [
"first knowledge of your AI Agent",
"second knowledge of your AI Agent"
],
"interval": "Your agent interval beetween each transaction of the Agent in ms,",
"chatId": "Your Agent Chat-id for isolating memory",
"maxIterations": "The number of iterations your agent will execute before stopping",
"mode": "The mode of your agent, can be interactive, autonomous or hybrid",
"memory": {
"enabled": "true or false to enable or disable memory",
"shortTermMemorySize": "The number of messages your agent will remember"
},
"plugins": ["Your first plugin", "Your second plugin"],
"mcpServers": {
"nxp_server_example": {
"command": "npx",
"args": ["-y", "@npm_package_example/npx_server_example"],
"env": {
"API_KEY": "YOUR_API_KEY"
}
},
"local_server_example": {
"command": "node",
"args": ["node /path/to/local_server/dist/index.js"]
}
}
}
您可以使用snakagent上的工具轻松创建您自己的代理配置
用法
提示模式
运行提示:
# start with the default.agent.json
pnpm run start
# start with your custom configuration
pnpm run start --agent="name_of_your_config.json" --models="name_of_your_config.json"
服务器模式
运行服务器:
# start with the default.agent.json
pnpm run start:server
# start with your custom configuration
pnpm run start:server --agent="name_of_your_config.json" --models="name_of_your_config.json"
可用模式

在你的项目中实现 Snak
- 安装 snak 包
#using npm
npm install @snakagent
# using pnpm
pnpm add @snakagent
- 创建代理实例
import { SnakAgent } from 'starknet-agent-kit';
const agent = new SnakAgent({
provider: new RpcProvider({ nodeUrl: process.env.STARKNET_RPC_URL }),
accountPrivateKey: process.env.STARKNET_PRIVATE_KEY,
accountPublicKey: process.env.STARKNET_PUBLIC_ADDRESS,
aiModel: process.env.AI_MODEL,
aiProvider: process.env.AI_PROVIDER,
aiProviderApiKey: process.env.AI_PROVIDER_API_KEY,
signature: 'key',
agentMode: 'interactive',
agentconfig: y,
});
const response = await agent.execute("What's my ETH balance?");
