mcs-auth-auth0

One credential. Every service. Auth0 Token Vault integration for the Model Context Standard (MCS).

Configure Gmail, Google Drive, Slack, GitHub, and Microsoft connections once in the Auth0 dashboard. Your agent accesses all of them through a single get_token(scope) call. No separate OAuth clients, no per-service credential management, no token refresh headaches.

Installation

pip install mcs-auth-auth0

Quick start

from mcs.auth.auth0 import Auth0Provider

provider = Auth0Provider(
    domain="my-tenant.auth0.com",
    client_id="...",
    client_secret="...",
    refresh_token="...",  # from auth setup or AuthPort connector
)

# One call -- Auth0 handles the Token Vault exchange (RFC 8693)
google_token = provider.get_token("gmail")
slack_token = provider.get_token("slack")
github_token = provider.get_token("github")

How it works

Your Agent                  Auth0 Token Vault         External Provider
    |                            |                          |
    |-- get_token("gmail") ----->|                          |
    |                            |-- RFC 8693 exchange ---->|
    |                            |<--- Google access token -|
    |<-- "ya29.a0..." ----------|                          |

The Auth0Provider exchanges an Auth0 refresh token for an external provider's access token via Token Vault. It doesn't know how the refresh token was obtained -- that's pluggable via AuthPort:

from mcs.auth.auth0 import Auth0Provider
from mcs.auth.oauth import OAuthConnector        # browser login
from mcs.auth.linkauth import LinkAuthConnector  # device-flow broker

# Browser-based login
provider = Auth0Provider(..., _auth=OAuthConnector(...))

# LinkAuth device-flow (no browser callback needed)
provider = Auth0Provider(..., _auth=LinkAuthConnector(...))

Built-in scope mapping

Custom mappings: Auth0Provider(..., connections={"myservice": "my-connection"})
