Automated route planning for Mastra AI

Create agents that calculate journeys by chaining `get_bus_routes` and `get_bus_stops`. Your workflow can identify the right line and locate the nearest stop automatically. This removes the need for manual lookup. The logic handles the discovery phase so your agent can focus on the final itinerary.

Mastra AI agents handling transit disruptions

Set up conditional branches that react to service changes using `get_service_alerts`. If the agent detects a delay, it triggers a retry or suggests an alternative route to the user. This logic keeps your transit workflows resilient. It handles the unexpected shifts in service quality without human intervention.

Synchronizing transit time in Mastra AI

Use `get_system_time` to align your agent's internal clock with the CTA tracker. This ensures your time-sensitive queries for arrivals are perfectly matched with the system's current state. Precision matters when timing connections. This tool keeps your multi-step workflows accurate and reliable.

Setup guide

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

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

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

Common questions about CTA MCP in Mastra AI

Add the server to your Mastra client configuration and spread the tools into your agent definition. This makes the transit functions available for your agent to call whenever a task requires local data.

Use the tool approval feature if you want to verify transit actions before they execute. It is ideal for workflows that involve automated trip scheduling.

You can configure your agents to poll status across the entire system. By iterating through route IDs, the agent builds a complete picture of the network health.

The server provides clear responses that your agent can process. If a specific stop ID is invalid, the tool returns an error that your workflow can catch and handle.

Your agent's interaction with the CTA service is ephemeral. We isolate the request to prevent any persistence of your transit lookup patterns.
