Index Rates via LlamaIndex MCP Server

Avoid relying on static documents for financial advice when rates change daily. This MCP lets your indexing pipelines fetch live yield structures on demand. By calling `calculate_cd_yield` inside your data ingestion, your agent indexes exact future values. The resulting vector store remains grounded in real math instead of outdated financial PDFs.

Query Market Benchmarks Directly

Modern RAG applications need context that goes beyond basic text files. Your agent must compare fixed assets against liquid alternatives during user queries. This integration calls `fetch_market_benchmarks` to pull current high-yield savings rates. It injects these fresh metrics directly into your query engine response.

Build Context-Rich Comparisons

Users do not want generic financial advice. They want specific, numbers-based comparisons that reflect the current economic reality. The system relies on `generate_investment_comparison` to construct detailed investment tables. Your RAG agent can then synthesize this structured data into natural, personalized responses.

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.

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 CD Return Calculator 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 CD Return Calculator tools.",
)
response = await agent.run("List recent CD Return Calculator data")
