Index Pennylane data in LlamaIndex

Turn your invoice history into a searchable knowledge base. By calling `list_customer_invoices`, your agent pulls data that LlamaIndex stores as vectors for instant semantic retrieval. Stop digging through static files. Your agent finds specific invoice details by querying the index rather than scanning through every record manually.

Ground AI answers with Pennylane MCP Server

Your agent provides answers backed by live data. Use `get_supplier_details` to ground your AI responses in verified procurement records rather than relying on probabilistic guesses. This setup ensures your agent reports accurate vendor information. Every piece of financial data used in your RAG pipeline comes directly from your live account.

Smart retrieval for financial reporting

Combine your accounting documents with live API results. Your agent uses `list_categories` to categorize incoming data before indexing it, ensuring your search results align with your accounting plan. This keeps your RAG application organized. Your agent understands the structure of your financial data because it interacts directly with the schema.

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

Common questions about Pennylane MCP in LlamaIndex

It uses the MCP tool spec to call endpoints like `list_customers` and `list_estimates`. The results are then indexed for your agent to query semantically.

You can refresh your index by re-running the tool calls. Simply trigger `list_supplier_invoices` again to pull the latest entries into your searchable knowledge base.

We treat your ledger entries as private. Data is pulled only when your agent requests it and is stored locally within your vector index, isolated from other users.

It works with all 13 provided tools. You choose which data to index, such as `list_products` for your service catalog or `list_customers` for your client base.

It bridges the gap between raw API data and meaningful insight. You get a searchable version of your business finance that your agent understands.
