Perplexity

Automated case correspondence tracking

Chain `get_matter_correspondence` into your agent workflows to monitor case progress automatically. If a new document appears, the agent triggers the next step in your process without manual oversight. This removes the manual check-in cycle. You define the logic, and the agent handles the polling and data extraction from LEAP Legal.

Conditional matter processing

Use `get_matter_details` to branch your logic based on case type or status. If a matter is marked as closed, the agent can stop further research tasks automatically. It handles the heavy lifting of legal logic. You just define the conditions, and the tool provides the raw data to make the call.

Reliable contact synchronization

Implement retries for `update_existing_card` calls to ensure data consistency. Mastra AI detects failures and attempts the update again, keeping your records accurate. It's about data integrity. By wrapping these calls in a workflow, you ensure that even if the network blips, the contact update eventually completes.

Setup guide

Set up LEAP Legal 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 LEAP Legal 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: "leap-legal-1-mcp-client",
  servers: {
    "leap-legal-1-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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