Index Sapling (Kallidus) employee records

Turn your employee directory into a queryable knowledge base. Using `list_employees`, you retrieve the full roster and index it so your LlamaIndex agent can answer questions about staff distribution instantly. This makes your HR data searchable by concept rather than just ID. Your agent understands who belongs to which department by querying the indexed results.

Ground AI answers in HR data

Stop guessing and start querying actual records. By using `get_employee` and `list_job_titles`, you provide the context needed for your agent to deliver accurate, fact-based responses. Your agent references these tools to verify title and compensation history. It then uses that information to construct answers based on reality rather than training data.

Monitor status via LlamaIndex

Track the lifecycle of your staff with `list_onboarding_tasks` and `list_offboarding_tasks`. When these are indexed, your agent can summarize pending tasks for any new hire. This keeps your team updated on transition progress. Your agent acts as a search interface for your HR status, providing updates whenever you ask.

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

Common questions about Sapling (Kallidus) MCP in LlamaIndex

Use the MCP tool spec to convert your server tools into a format LlamaIndex understands. Then, run your retrieval process to populate your vector store with the returned data.

Updates occur whenever you re-run your query or indexer. Since the server provides live data, your index stays as fresh as your last request.

Yes. You can use the allowed_tools filter to restrict which parts of the HR data are accessible to your agent during its knowledge search.

The server remains live, but your indexed knowledge base depends on how you configure your local storage. You choose when to update the index with new API results.

Vinkius uses ephemeral isolated environments. Your HR records—names, emails, and IDs—are only accessed when your specific query requires them for indexing.
