Arcade Serve - Serving infrastructure for Arcade tools and workers

Arcade Serve

Serving infrastructure for Arcade tools and workers.

Overview

Arcade Serve provides the infrastructure for serving Arcade tools:

• FastAPI Worker: High-performance FastAPI-based worker implementation
• MCP Server: Model Context Protocol server for tool integration
• Core Abstractions: Base worker classes and components
• Authentication: Auth utilities and routing
• Runtime Management: Tool execution and lifecycle management

Installation

pip install arcade-serve

Usage

To add a toolkit to a hosted worker such as FastAPI, you can register them in the worker itself. This allows you to explicitly define which tools should be included on a particular worker.

Here is an example of adding the math toolkit (pip install arcade-math) to a FastAPI Worker:

import arcade_math
from fastapi import FastAPI
from arcade_tdk import Toolkit
from arcade_serve.fastapi import FastAPIWorker

app = FastAPI()

worker_secret = os.environ.get("ARCADE_WORKER_SECRET")
worker = FastAPIWorker(app, secret=worker_secret)

worker.register_toolkit(Toolkit.from_module(arcade_math))

Here is an example of adding the math toolkit (pip install arcade-math) to a MCP Worker

import arcade_math
from arcade_core.catalog import ToolCatalog
from arcade_serve.mcp.stdio import StdioServer

# 1. Create and populate the tool catalog
catalog = ToolCatalog()
catalog.add_module(arcade_math)


# 2. Main entrypoint
async def main():
    # Create the worker with the tool catalog
    worker = StdioServer(catalog)

    # Run the worker
    await worker.run()


if __name__ == "__main__":
    import asyncio

    asyncio.run(main())
