Stream Onboarding Tasks to React

The `list_onboarding_tasks` tool pulls the exact status of new hire integrations directly from the API. Your AI client can grab this data while Vercel AI SDK streams the progress live to your dashboard. You don't have to wait for the entire payload to finish. Users see the checklist populate in real-time as the MCP Server fetches task updates.

Build Live Org Charts

The `list_employees` tool grabs names, emails, and internal IDs for everyone in the company. Pass this to `get_employee` to pull employment history and compensation details for specific individuals. Combine these with `list_departments` and `list_teams` to generate interactive organizational maps. The streaming text function renders the hierarchy instantly in your Svelte or Vue frontend.

Render Offboarding Status Instantly

The `list_offboarding_tasks` tool acts as the source of truth for compliance checks when someone leaves the company. You hook this up to your Edge functions to verify access revocations. Your frontend displays the remaining security tasks live. HR managers see exactly what needs doing without refreshing the page or waiting for a slow backend response.

Setup guide

Set up Sapling (Kallidus) MCP in Vercel AI SDK

Prerequisites

Node.js 18+ and a TypeScript project
ai + @modelcontextprotocol/sdk packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies

Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).
2

Create the Streamable HTTP transport

Use StreamableHTTPClientTransport with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and use tools

Call mcpClient.tools() to auto-discover all Sapling (Kallidus) tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.
4

Works with any model provider

Swap openai("gpt-4o") for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.

index.ts

import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: openai("gpt-4o"),
  tools,
  prompt: "List recent Sapling (Kallidus) transactions",
});

console.log(text);
await mcpClient.close();

Common questions about Sapling (Kallidus) MCP in Vercel AI SDK

Install `@ai-sdk/mcp` and use `createMCPClient`. Point the transport URL to your Vinkius endpoint and call `mcpClient.tools()` to pass the HR tools to `streamText`.

Yes. Call the employee tools and the SDK will stream the JSON or text response straight to the client. You avoid loading spinners completely.

It runs perfectly on the Edge. You just need to ensure you close the connection with `mcpClient.close()` after the HR query finishes.

You pass your Vinkius endpoint token in the HTTP transport configuration. The MCP protocol handles the actual API routing securely behind the scenes.

This server reads highly sensitive employment history, compensation details, and personal emails. The V8 Isolate Sandbox ensures this HR data is processed ephemerally and never stored on disk.
