Swarmauri Auth IDP Keycloak

Keycloak OAuth 2.0 / OAuth 2.1 / OIDC 1.0 identity providers packaged for Swarmauri deployments.

Features

• PKCE-enabled Authorization Code flows that integrate with Keycloak realm issuers.
• Discovery-driven OAuth 2.1/OIDC login that validates ID tokens against realm JWKS.
• UserInfo enrichment for deployments that require normalized profile payloads.
• Retry-aware HTTP integration tuned for Keycloak endpoints.
• ComponentBase-compatible models registered under swarmauri.auth_idp entry points.

Installation

pip

pip install swarmauri_auth_idp_keycloak

uv (project)

uv add swarmauri_auth_idp_keycloak

uv (environment)

uv pip install swarmauri_auth_idp_keycloak

Usage

import asyncio
from pydantic import SecretBytes, SecretStr
from swarmauri_auth_idp_keycloak import KeycloakOAuth20Login

login = KeycloakOAuth20Login(
    issuer="https://kc.example.com/realms/myrealm",
    client_id="keycloak-client-id",
    client_secret=SecretStr("keycloak-client-secret"),
    redirect_uri="https://app.example.com/callback",
    state_secret=SecretBytes(b"replace-with-random-bytes"),
)

# Optional: preload discovery metadata when running outside your Keycloak instance.
login.discovery_cache = {
    "authorization_endpoint": "https://kc.example.com/realms/myrealm/protocol/openid-connect/auth",
    "token_endpoint": "https://kc.example.com/realms/myrealm/protocol/openid-connect/token",
    "userinfo_endpoint": "https://kc.example.com/realms/myrealm/protocol/openid-connect/userinfo",
}

async def run_flow() -> None:
    auth = await login.auth_url()
    print(auth["url"])
    # Redirect the browser to `auth["url"]`, then capture the callback `code` and `state`.
    # Later, call `login.exchange_and_identity(code, state)` inside your callback handler.

asyncio.run(run_flow())

Workflow Summary

1. Call auth_url() and redirect the browser to the returned URL.
2. Persist the state and verify it during the callback handler.
3. Exchange the authorization code through exchange_and_identity() to obtain tokens and profile metadata.
