Mastra AI workflow integration

Incorporate `get_country` into your Mastra agent graph. If a lookup fails, the workflow engine automatically retries the operation. Your agents now have reliable access to geographic metadata. It turns raw location strings into actionable objects for your backend.

Automated regional filtering for Mastra AI

Use `list_cities_by_state` within your agent steps to define regional boundaries. You can chain this with other tools to validate addresses. The system handles the serialization between the MCP Server and your TypeScript agent. Logic remains clean and maintainable.

Managed geographic lookups in Mastra AI

Deploy `list_states` as a core step in your data pipeline. The agent fetches the necessary hierarchy without extra boilerplate code. This MCP Server provides the structure your agents need to make informed decisions. It bridges the gap between your code and global data.

Setup guide

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

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

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