Perplexity

Automated pipeline validation for Mastra AI

Integrate `test_glob` into your Mastra AI workflows to gate file processing steps. Your agents can verify paths before triggering heavy operations. This keeps your multi-step agents from wasting time on files that should have been ignored. You define the pattern and the tool handles the boolean check.

Reliable logic for Mastra AI agents

Mastra AI agents need precise tools to handle complex tasks. `test_glob` provides that precision by mirroring the logic used by standard developer tools. You won't find unexpected behavior here. It matches paths exactly how you expect git to handle them.

Handle file exclusions in Mastra AI

Define complex ignore rules and let your agents apply them dynamically. The `test_glob` tool makes this logic easy to test and verify. Your workflow gains the ability to filter inputs based on patterns you define. It's a simple way to keep your data processing clean.

Setup guide

Set up Glob Pattern Tester 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 Glob Pattern Tester 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: "glob-pattern-tester-mcp-client",
  servers: {
    "glob-pattern-tester-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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