@authorityrail/plugin-langgraph

AuthorityRail governance plugin for LangGraph. One import = ARES-v1 Certified Action Records on every node.

Install

npm install @authorityrail/plugin-langgraph

Quickstart

import { authorityRailNode, authorityRailChannels } from "@authorityrail/plugin-langgraph";
import { StateGraph } from "@langchain/langgraph";

const safeAnalyze = authorityRailNode(analyzeFn, {
  gate_url: process.env.AUTHORITYRAIL_GATE_URL!,
  api_key: process.env.AUTHORITYRAIL_API_KEY!,
  action_type: "ANALYZE_DOCUMENT",
  agent_id: "doc-analyzer",
  resource: "documents/*",
  model_provider: "anthropic",
  model_id: "claude-opus-4-6",
});

const graph = new StateGraph({ channels: authorityRailChannels() });
graph.addNode("analyze", safeAnalyze);

Every invocation of safeAnalyze is gated through AXAP before execution:

• ALLOW → node runs, _ar_car_id attached to state
• DENY → AuthorityRailDenyError thrown
• ESCALATE → AuthorityRailEscalateError thrown (configurable)
