App Service Custom AI Middleware

Python middleware and tools for AI agents hosted behind Azure App Service Authentication and App Service Hooks.

Install

pip install aw-appservice-custom-ai-middleware-extension

The distribution name is aw-appservice-custom-ai-middleware-extension. The stable Python import remains:

import app_service_extensions as ase

For Azure Functions:

pip install "aw-appservice-custom-ai-middleware-extension[functions]"

For Azure Functions hosted skills:

pip install "aw-appservice-custom-ai-middleware-extension[hosted-skills]"

The hosted-skills integration patches runtime seams that are not yet public API. Its dependency range is intentionally narrow and is expanded only after the integration suite passes against a new runtime release.

Azure Functions

Configure the middleware before creating the hosted-skills app, then attach it to the generated Function app:

import app_service_extensions as ase
from azure_functions_agents import create_function_app

ase.configure()
app = create_function_app()
ase.configure(app)

The package preserves App Service caller identity and the opaque X-MS-Hook-Invocation recursion chain for same-site callbacks. It does not send those credentials to third-party MCP servers.
