Automated catalog mapping with Mastra AI

Let your agents hunt down datasets on autopilot. Using `search_catalog`, Mastra AI can periodically scan the Catalonian catalog, identify new datasets, and trigger automated sync workflows. If the open data portal is slow or rate-limited, Mastra's built-in retry engine backs off and tries again. You do not have to write custom error-handling loops for your data pipelines.

Conditional branching for SoQL queries

Create smart data flows that react to API responses. When `query_dataset` runs, Mastra can check if the result set is empty and branch to a broader search or notify your team. This lets you build autonomous data monitors. For example, your agent can check for new environmental or transport logs and only trigger downstream actions when specific conditions are met.

Human-in-the-loop approvals for MCP Server tool calls

Do not let your agent run wild with complex SoQL queries. Mastra allows you to require manual approval before executing `query_dataset` with heavy `$limit` or `$where` parameters. You review the generated query in your console, approve it, and let the agent finish the job. It is a safe way to run automated analytical workflows without wasting API credits.

Setup guide

Set up Dades Obertes Catalunya 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 Dades Obertes Catalunya 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: "dades-obertes-catalunya-mcp-client",
  servers: {
    "dades-obertes-catalunya-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about Dades Obertes Catalunya MCP in Mastra AI

Instantiate the client using your Vinkius HTTP URL. Then, spread the tools directly into your Mastra agent configuration to give it immediate access to the public datasets.

Yes, Mastra has built-in exponential backoff. If the Catalonia API throttles your query_dataset call, the framework automatically pauses and retries without breaking your workflow.

Use the requireToolApproval setting on your agent. This pauses execution whenever the agent wants to run query_dataset or search_catalog, waiting for your green light.

Absolutely. Mastra's workflow engine lets you schedule regular checks, querying the catalog for updates and processing the results automatically.

All SoQL parameters and dataset search terms are processed in memory within your own Mastra deployment. The connection to the Catalonia API is direct and ephemeral, meaning your exact query logic remains private.
