Perplexity

Conditional identity orchestration in Mastra AI

Construct complex branching logic that reacts to account status. Use `get_user` to check for existing credentials before deciding whether to invoke `create_user` or `patch_user` within your agent workflows. If an operation fails, you can trigger a retry loop or notify an admin. The workflow engine ensures that your identity lifecycle remains consistent even when external services fluctuate.

Automated tenant and role management

Automate the setup of multi-tenant environments by chaining `create_tenant` and `create_application_role`. Your agents can provision entire environments for new customers without manual intervention. This keeps your infrastructure-as-code consistent with your identity-as-code. Every step is logged, providing a clear audit trail of who created what and when.

Graceful failure handling for identity operations

Wrap your identity tasks in retry blocks using the built-in workflow engine. If `issue_jwt` times out, your agent can wait and try again with exponential backoff. This prevents transient network issues from breaking your onboarding process. Your agents handle the heavy lifting while you define the business rules for success and failure.

Setup guide

Set up FusionAuth (Enterprise Identity & Auth) MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All FusionAuth (Enterprise Identity & Auth) tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "fusionauth-enterprise-identity-auth-mcp-client",
  servers: {
    "fusionauth-enterprise-identity-auth-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "FusionAuth (Enterprise Identity & Auth) Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to FusionAuth (Enterprise Identity & Auth) tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent FusionAuth (Enterprise Identity & Auth) transactions"
);
console.log(result.text);
