Perplexity

Conditional subscriber management

Define complex agent workflows that react to subscriber changes. Use `upsert_subscriber` within a Mastra agent to update contact records based on external events. If the tool call fails due to a network blip, the framework handles the retry automatically. It ensures your database stays in sync with platform settings.

Audience segmentation and logic

Your agents can query list identity properties using `list_audience_segments` to make smarter routing decisions. It allows the agent to decide which campaign to target based on real subscriber counts. Use `list_contacts` to pull specific segments into the agent's memory. The agent then processes this data to trigger the next step in your workflow.

Automated campaign monitoring

Mastra AI agents watch your marketing performance by calling `list_marketing_campaigns` at set intervals. If a campaign hits a performance threshold, the agent can pivot strategy. It parses complex campaign metadata via `list_supplementary_data` to inform its decisions. This setup keeps your operations running without constant human intervention.

Setup guide

Set up Cordial 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 Cordial 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: "cordial-mcp-client",
  servers: {
    "cordial-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent Cordial transactions"
);
console.log(result.text);

Common questions about Cordial MCP in Mastra AI

You add the server to your agent definition and spread the available tools into the agent's context. The framework then handles the tool execution during your agent's thinking process.

Yes, you can enable requireToolApproval in your agent config. This forces the agent to ask for your sign-off before it modifies any subscriber records.

The server logs every request and response through the standard MCP transport. You can inspect the full exchange in your local console or deployment logs.

The connection lasts for the duration of the agent's task. Once the workflow finishes, the ephemeral session terminates automatically.

Data is encrypted in transit using TLS and kept inside an isolated runtime. We strip all non-essential metadata before the agent processes the subscriber records.
