Automated workflow logic for Mastra AI

Chain your agent tasks with `get_holidays` or `get_timezone` to build complex scheduling logic. If a holiday check returns true, the agent triggers a different branch in your workflow. You define the flow, and the agent handles the execution. It makes your backend logic predictable.

Retry logic with Abstract API

Mastra AI handles tool failures automatically if you configure the retry policy. Use `validate_vat` to confirm company records before your agent moves to the next step of an onboarding flow. If the API returns a transient error, the agent waits and tries again. You don't have to write manual loops.

Multi-step validation for agents

Your agent can use `validate_email` to verify contact records before hitting your CRM. It performs the check and decides whether to proceed with the record creation. This keeps your data clean without manual human intervention. The agent makes the call based on the tool output.

Setup guide

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

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

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

Common questions about Abstract API MCP in Mastra AI

Add the server URL to your MCP client config in Mastra. The framework automatically detects the available tools and lists them for your agents.

Yes, you can enable human-in-the-loop approval for any Abstract API call. The agent pauses until you sign off on the action.

Absolutely. You can define steps where the output of one tool feeds into the next. The agent handles the state between calls.

Deploy to any cloud using the standard Mastra CLI. The Vinkius endpoint remains accessible to your production agents.

The server treats VAT numbers as transient request data. It doesn't persist your company data once the validation check completes.
