Automate test suites in Mastra AI

Use `run_service_tests` to execute your full test suite triggered by agent logic. This lets you build workflows that react to production failures. If a service fails, the agent can trigger a re-run or alert your team. You define the logic, the server handles the execution.

Sync your specifications automatically

Keep your documentation and tests in lockstep with `sync_specification`. Your agent pushes your latest OpenAPI or Swagger files to your monitoring setup. This removes the manual work of updating your test definitions. Just provide your token and the agent handles the rest.

Execute targeted tests with Mastra AI

Call `run_specific_test` to isolate issues when a workflow hits a snag. This is faster than running the entire suite for every minor check. Your agents can drill down into specific failures. It saves time and preserves your API rate limits.

Setup guide

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

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

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