Perplexity

Automated financial research workflows

Mastra AI triggers `get_company_profile` to build background reports. It creates a structured flow that gathers data before you even ask. If the initial request fails, the framework retries automatically. This ensures your research tasks complete even when network conditions fluctuate.

Conditional market analysis

Use `get_basic_financials` to trigger branching logic in your agents. If a company meets your margin criteria, the workflow proceeds to the next step. Your agent makes decisions based on the data returned. It handles the logic so you only review the final, filtered results.

Crypto and stock tracking

List available assets with `list_crypto_symbols` to define your monitoring scope. Your agent keeps an eye on the market based on these defined lists. It updates the watch list automatically. You define the rules, and the agent executes the lookups using the provided tools.

Setup guide

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

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

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