How to Use the Zoho Invoice MCP in LlamaIndex

Q: How can LlamaIndex help me query old Zoho Invoice records?

By indexing the results from listinvoices, you create a searchable knowledge base. You then query that index, and the system returns answers grounded in your actual billing data.

Q: Does LlamaIndex support tracking multiple Zoho Invoice accounts?

Yes. Since the MCP Server exposes listcontacts and listinvoices, you can feed results from multiple sources into a single, unified index for comprehensive searching.

Q: If I update items in an invoice using Zoho Invoice and LlamaIndex, how is that tracked?

The output of the updateinvoiceitems tool can be immediately indexed. This ensures your RAG application reflects the most current state of the billing record.

Q: Can LlamaIndex handle deletions for Zoho Invoice records?

While the tool allows deletion via deleteinvoice, indexing generally focuses on reading data. You'd use the live API call to delete, and then the knowledge base would reflect that record is gone.

Search Past Financial Records with LlamaIndex

LlamaIndex indexes the output of `list_invoices`, turning historical billing data into a searchable vector store. You query past sessions or configurations and get answers grounded in actual API invoice details, not guesswork. This means you can ask questions like, 'What was the total for Client X last quarter?' and LlamaIndex pulls the exact answer from your indexed Zoho Invoice records.

Manage Contacts through MCP Server Tools

Need to know if a contact exists? Use `get_contact` to pull details, then index that data. Later, you can query your knowledge base using LlamaIndex and ask follow-up questions about that specific client record. This ability combines live API calls with document retrieval, giving you answers from both the current state and historical context.

Process Billing Changes in LlamaIndex

You can use `update_invoice_items` to change billing records. After running this tool, index the updated record. This way, any future query against your RAG application will reflect the latest changes you made to Zoho Invoice. It’s perfect for building applications where live API data and documents must combine into one unified source of truth.

Setup guide

Set up Zoho Invoice MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Zoho Invoice MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

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

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to Zoho Invoice tools.",
)
response = await agent.run("List recent Zoho Invoice data")
