arp-standard-server 0.2.6

FastAPI server scaffolding for the ARP Standard (v1).

ARP Standard Python Server (arp-standard-server)

FastAPI server scaffolding for implementing ARP components with spec-aligned request/response types.

Install

python3 -m pip install arp-standard-server

Usage

from arp_standard_server.daemon import BaseDaemonServer
from arp_standard_server import AuthSettings
from arp_standard_model import DaemonCreateInstancesRequest, InstanceCreateRequestBody

class MyDaemon(BaseDaemonServer):
    async def create_instances(self, request: DaemonCreateInstancesRequest):
        body = request.body
        # business logic here
        return ...

app = MyDaemon().create_app(auth_settings=AuthSettings(mode="disabled"))

Service base classes

• BaseRuntimeServer
• BaseToolRegistryServer
• BaseDaemonServer

Request objects

All server methods accept a single request object from arp_standard_model:

• *Params for path/query parameters
• *RequestBody for JSON bodies
• *Request wrappers with params and/or body

Abstract method enforcement

Base server classes use ABC + @abstractmethod. Instantiating a class that does not implement all required endpoints raises a TypeError before the app is created.

Authentication (JWT Bearer)

app = MyDaemon().create_app(
    auth_settings=AuthSettings(
        mode="required",
        issuer="https://issuer.example.com/realms/arp",
        audience="arp-daemon",
    )
)

Streaming (NDJSON)

NDJSON endpoints currently use plain text payloads. Streaming helpers are planned but not implemented yet.
