Perplexity

Mastra AI Workflow Automation

Create a chain where `list_investors` triggers `get_investor_portfolio`. If a call fails, your Mastra AI agent retries automatically. This approach turns static data into an active research pipeline. You define the logic, and the agent executes the steps sequentially.

Investor Intelligence Loops

Query `get_investor` to pull firm strategy and focus areas. You can branch your Mastra AI agent logic based on the asset class returned. This removes the need for manual data entry. Your agents handle the research phase while you focus on the outcome.

Competitor Monitoring Agents

Deploy agents that use `get_org_competitors` to track market shifts. You can set up alerts that fire when a new competitor enters a specific industry. Mastra AI manages the state of these checks. It keeps track of previous results to identify changes in the market landscape.

Setup guide

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

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

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