How to Use the LEAP Legal MCP in Mastra AI

Q: How do I handle failed billing runs using LEAP Legal and Mastra AI?

You configure a workflow that calls getleapbill and catches any API errors. Mastra AI uses its built-in retry engine to repeat the request, ensuring temporary network drops don't stall your invoicing pipelines.

Q: Can I automate client onboarding with LEAP Legal and Mastra AI?

Yes, you build a multi-step workflow that triggers createleapcontact followed immediately by createleapmatter. The framework passes the newly generated contact ID to the case opening tool without any human data entry.

Q: How do I sync custom fields across my cases?

Use listleapcustomfields to fetch the schema, then map your incoming payload to the correct custom fields before updating the matter.

Q: Where is my firm's case data stored during workflow execution?

Your active legal matters and documents accessed via listleapdocuments remain entirely within your secure LEAP Legal database. The MCP Server executes in an ephemeral sandbox, processing data in-memory without caching or writing to local disks.

Perplexity

Chain case initiation with automated contact setup

The `create_leap_contact` tool serves as the initial step in your automated client onboarding workflows. Mastra AI chains this tool directly to `create_leap_matter` to ensure no case is ever opened without a validated client ID attached to it. If the contact creation fails due to a network hiccup, the workflow engine automatically triggers an exponential backoff retry. This guarantees that your legal operations run reliably without manual intervention from your IT staff.

Run multi-step billing audits with automatic retries

The `list_leap_time_entries` tool gathers all unbilled hours for a specific matter to initiate the invoicing process. Your Mastra AI agent evaluates these entries against active rates and executes `get_leap_bill` to verify accuracy before finalizing. When billing discrepancies occur, the agent halts the workflow and routes the draft to a human-in-the-loop approval step via MCP. This prevents incorrect invoices from reaching clients while keeping the administrative pipeline moving.

Sync matters with calendar events using Mastra AI

The `list_leap_calendar_events` tool monitors scheduled court dates to trigger automated case preparation steps. Mastra AI uses this event data to run `update_leap_matter`, keeping case statuses updated based on real-world legal deadlines. By connecting this MCP Server, your agents run background checks on upcoming hearings without manual oversight. You write the workflow logic once, deploy it to the cloud, and let the system handle the scheduling updates.

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-mcp-client",
  servers: {
    "leap-legal-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);
