How to Use the Wave Financial MCP in LlamaIndex

Q: Can LlamaIndex handle multiple Wave Financial business structures?

Absolutely. You can index results pulled from listbusinesses and then structure your RAG application to query specific divisions or subsidiaries, keeping the knowledge base segmented yet connected.

Q: If I want to query a client's product history, how do I use LlamaIndex?

You run listproducts first, and then index that list alongside the resulting invoices from listinvoices. This allows you to ask questions like, 'What were our top-selling items last year?' years later.

Perplexity

Indexing Historical Transactions

LlamaIndex turns raw financial records into searchable knowledge. When your agent queries for past spending, it first calls `list_transactions` and indexes the results. This means you can ask natural language questions like, 'What did we spend on utilities last quarter?' The answer isn't just a list; LlamaIndex grounds the response in the actual API data retrieved from Wave Financial, eliminating any guesswork or hallucinations.

Semantic Search for Business Configurations

Forget keyword searches. If you want to know what sales taxes are configured for a specific location, LlamaIndex indexes the output of `list_sales_taxes`. Your agent can then answer complex questions like, 'Which business has tax rates different from the default?' This ability lets you combine live API data with your internal documents in one unified index. You’re building true knowledge retrieval systems.

Retrieving Vendor and Customer History

Need to understand a vendor's history? LlamaIndex can take the output from `list_vendors` and combine it with information from `list_bills`. You write a query that asks, 'What are all unpaid bills for Acme Corp?' The result is stored in your vector store. Later, you can retrieve this specific financial relationship months later without having to rerun the exact API calls.

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Wave Financial 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 Wave Financial tools.",
)
response = await agent.run("List recent Wave Financial data")
