sunra.ai Client Libraries

English | 简体中文

About the Project

This repository contains the official client libraries for sunra.ai, a platform for deploying and running AI models. The libraries provide robust and user-friendly interfaces for integrating sunra.ai endpoints into your applications across multiple programming languages.

Available Client Libraries# 🐍 Python Client

• Location: clients/python/
• Package: sunra-client (PyPI)
• Features: Synchronous and asynchronous support, streaming responses, file uploads
• Installation: pip install sunra-client

📦 JavaScript/TypeScript Client

• Location: clients/javascript/
• Package: @sunra/client (npm)
• Features: Works in Web, Node.js, and React Native environments
• Installation: npm install @sunra/client

☕ Java Client

• Location: clients/java/
• Package: ai.sunra.client:sunra-client (Maven Central)
• Features: Synchronous, asynchronous, and Kotlin coroutine support
• Installation: implementation "ai.sunra.client:sunra-client:0.1.6"

Quick Start

Before using any client library, you'll need to:

1. Sign up at sunra.ai
2. Get your API key from the dashboard
3. Set your API key as an environment variable: export SUNRA_KEY=your-api-key

Python Example

import sunra_client

# Simple synchronous call
result = sunra_client.subscribe(
    "black-forest-labs/flux-kontext-pro/text-to-image",
    arguments={"prompt": "a cute cat, realistic, orange"}
)
print(result["images"][0]["url"])

# Asynchronous call
async def main():
    result = await sunra_client.subscribe_async(
        "black-forest-labs/flux-kontext-pro/text-to-image",
        arguments={"prompt": "a cute cat, realistic, orange"}
    )
    print(result["images"][0]["url"])

JavaScript Example

import { createSunraClient } from "@sunra/client";

const sunra = createSunraClient({
  credentials: process.env.SUNRA_KEY,
});

const result = await sunra.subscribe(
  "black-forest-labs/flux-kontext-pro/text-to-image",
  {
    input: {
      prompt: "a cute cat, realistic, orange"
    }
  }
);
console.log(result.images[0].url);

Java Example

import ai.sunra.client.*;

var sunra = SunraClient.withEnvCredentials();

var result = sunra.subscribe(
    "black-forest-labs/flux-kontext-pro/text-to-image",
    SubscribeOptions.<JsonObject>builder()
        .input(Map.of("prompt", "a cute cat, realistic, orange"))
        .resultType(JsonObject.class)
        .build()
);
System.out.println(result.getData());

Server Proxy

For client-side applications, we provide a server proxy to securely handle API calls without exposing your credentials. Available for popular frameworks:

• Location: server-proxy/
• Package: @sunra/server-proxy (npm)
• Supports: Next.js, Express, Hono, Remix, SvelteKit

MCP Server (Model Context Protocol)

The MCP server provides a universal interface for AI model tools, enabling seamless integration with modern code assistants and IDEs such as Cursor and Claude Desktop. It acts as a bridge between Sunra.ai and your development environment, exposing Sunra's models and tools via the Model Context Protocol.

Why use the MCP server?

• Enables code assistants (like Cursor, Claude, etc.) to access Sunra models and tools directly from your editor
• Supports listing models, fetching schemas, submitting jobs, streaming results, and more
• Secure: API keys are managed via environment variables or runtime configuration
• No need to write glue code—just run the server and connect your tool

Quick Start## 1. Install & Run (no local build needed)

npx @sunra/mcp-server --transport http --port 3925

2. For Cursor IDE

• Add to your .cursor/mcp.json:

{
  "mcpServers": {
    "sunra-mcp-server": {
      "url": "http://localhost:3925/sse"
    }
  }
}

• Set your API key:

  export SUNRA_KEY="your-api-key-here"
  

• In Cursor, select the sunra-mcp-server and use tools like list-models, model-schema, etc.

3. For Claude Desktop (Anthropic)

• Start the server in stdio mode (default):

  npx @sunra/mcp-server
  

• In Claude Desktop settings, add a new MCP server:
• Type: Local executable
• Command: npx @sunra/mcp-server
• Environment Variables:

  SUNRA_KEY=your-api-key-here
  

• In Claude, select the sunra-mcp-server and use the available tools.

4. Advanced Usage & Documentation

• See mcp-server/README.md for full tool list, development, and troubleshooting.
