Running Config Checks in Mastra AI

If your multi-step workflow needs to check project settings—say, fetching required API keys from a `pyproject.toml` file—use this tool. You pass the config and ask for the JSON output. This allows Mastra's built-in workflow engine to make decisions based on actual configuration data.

MCP Server for Failure Handling in Mastra AI

The server handles deterministic conversion of config files, which is critical when building reliable workflows. If one step fails, you might need to read an alternate setting from a `Cargo.toml` file. The tool ensures that the data structure remains intact across conversions.

Deterministic Data for Mastra AI Workflows

The `parse_toml` function guarantees consistent parsing of complex elements like arrays and datetime values. This consistency is non-negotiable when your workflow needs to retry steps or branch conditionally. You get predictable data structures, which keeps your failure handling logic solid.

Setup guide

Set up TOML Parser Engine 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 TOML Parser Engine 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: "toml-parser-engine-mcp-client",
  servers: {
    "toml-parser-engine-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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