Automate Offboarding Workflows

The `list_offboarding_tasks` tool checks exactly what needs to happen when an employee departs. Your agent uses this to trigger conditional branches in Mastra AI based on incomplete items. If a task fails or the API times out, the built-in exponential backoff retries the request. You get reliable compliance checks without writing custom error handling logic.

Sync Onboarding Progress

The `list_onboarding_tasks` tool grabs the current state of a new hire's setup process. You can map this data into a Mastra workflow that alerts IT if equipment provisioning falls behind schedule. Add human-in-the-loop approvals before the workflow proceeds. Use `requireToolApproval` so a manager signs off before the system marks the orientation as complete.

Map Company Structure

The `list_locations` and `list_departments` tools return the exact site and business unit configurations from Sapling. Your AI client pulls these lists to route internal tickets to the right regional HR rep. You can deploy this routing logic to any cloud with a single command. The MCP Server handles the API complexity while your workflow focuses on the business logic.

Setup guide

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

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

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

Common questions about Sapling (Kallidus) MCP in Mastra AI

Initialize a new `MCPClient` with your Vinkius URL. Call `mcpClient.listTools()` and spread the HR functions directly into your agent's tool array.

The framework automatically applies exponential backoff to any failed tool calls. If the HR system drops a request, the agent tries again before failing the workflow step.

Set the `requireToolApproval` flag on sensitive operations. The workflow will pause and wait for an admin to confirm before executing the next step.

Mastra automatically detects whether to use Streamable HTTP or SSE based on the MCP endpoint. You just provide the URL and it handles the connection mechanics.

The integration touches internal IDs, job titles, and group assignments. The zero-trust architecture guarantees this personnel data flows directly to your agent without being cached by the server.
