Reva AI SDK

Installable Python SDK for Reva AI authorization, discovery, and proxy helpers. It lets your agents (FastAPI, LangChain, LangGraph, CrewAI, AutoGen) and MCP servers enforce decisions from the Reva Trust Gateway (RTG / PDP) on every hop.

Installation

pip install reva-ai-authz

Requires Python 3.10+.

Quick start

from reva_ai.sdk.ai import reva_ai_authorise

RTG Authentication

Set RTG_AUTH_TOKEN when the Reva platform requires a per-tenant API key in addition to RTG_URL.

export RTG_URL="https://rtg.example.com"
export RTG_AUTH_TOKEN="..."

When RTG_AUTH_TOKEN is set, SDK calls to RTG PDP evaluation, token enrichment, final-turn recording, and discovery logging include the API key on a dedicated header:

X-API-Token: <RTG_AUTH_TOKEN>
Authorization: Bearer <end-user JWT>      # unchanged

The Authorization header is left untouched so it continues to carry the end-user token that PDP needs for policy evaluation. The gateway prefers X-API-Token for perimeter authentication and falls back to Authorization only when X-API-Token is absent. If RTG_AUTH_TOKEN is unset, the SDK adds no X-API-Token header.
