Ground LlamaIndex RAG applications in real bond math

Stop letting your retrieval systems guess bond returns based on outdated documents. This MCP lets you inject precise yield calculations directly into your search index. Your agent can query live math instead of relying on static PDFs. Let's break down the yield. By connecting this tool, your RAG pipeline can pull real-time yields alongside historical text. It gives your users answers that are mathematically accurate and fully grounded in current market reality.

Index calculation results for semantic search

LlamaIndex does more than just run calculations. It lets you index the outputs of `get_bond_yield_metrics` directly into vector stores for future queries. This MCP makes the math searchable alongside your text documents. This creates a searchable knowledge base of your bond evaluations. Instead of recalculating the same bond metrics repeatedly, your agent can retrieve past calculations instantly. It saves time and API calls.

Build unified query engines for fixed income

Combine your unstructured financial reports with structured yield metrics. This tool allows your query engine to pull qualitative risk descriptions from documents and quantitative sensitivity metrics from the calculator. The user gets a complete picture in one response. You can filter which tools are active using the standard tool specification helpers. This ensures your agent only calls the calculator when the query explicitly demands bond math. It keeps your pipeline fast and efficient.

Setup guide

Set up Bond Yield Calculator 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 Bond Yield 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 Bond Yield Calculator tools.",
)
response = await agent.run("List recent Bond Yield Calculator data")

Common questions about Bond Yield Calculator MCP in LlamaIndex

Install the LlamaIndex MCP tool package and initialize the basic client. Convert the client tools into a tool spec and pass them to your function agent. The agent is now ready to compute yields.

Yes, you can. You can capture the structured yield outputs and insert them into your vector store as document nodes. This makes the math searchable alongside your text documents.

Yes, it supports standard data access protocols. You can enable resource loading to let your agent inspect the underlying calculation schemas and parameters directly.

Yes, you can use the allowed tools filter during initialization. This restricts the agent to only the bond calculation tools, preventing unnecessary tool calls.

Absolutely. Your bond prices, coupon values, and face values are encrypted in transit. Vinkius processes these calculations in a secure sandbox, and we never write your financial inputs to any persistent logs or databases.
